This Italian Flashbike has real amperage behind its high-voltage glitter.
It's called horsepower, the stuff that sparks 11-second quarter-miles and makes
the kind of speed that has the scenery backing up in a hurry. Now who needs to
be Italian to understand that?
Italian sport bike with a twist. Its handling is slow and stable, its ride
stiff-legged, its seating position the classic road-racing hunker-down-on-it,
its mechanical design both interesting and unusual. So what's the twist? This
1982 Jota squirts through the quarter-mile in 11.93 seconds—and its 115-mph
terminal speed, exceptional for any bike, is especially remarkable for a
machine with such long-legged gearing. Only a few muscle-bound Super-bikes
geared 10 to 15 percent lower can beat it: the Suzuki GS1100 and Ka-tana, and
the Kawasaki GPz1100 and KZ1000.
This speed and quickness originate in a series of 1982 changes. Although a
cursory examination will uncover little, the 1982 Jota contains no fewer than
227 component changes. A new cylinder head that's an adaptation of the head used
by the factory on the 1976 works racers is primarily responsible for the
performance increase. The 70-degree valve angle is the same as that of former
models, but the combustion chambers are shallower and the valve heads 2.0mm
larger. These new standard valves are the same works valves offered as a racing
modification since 1976. New camshafts feature slightly more lift, which helps
power at lower engine speeds. The pistons have a flattened dome yet still retain
a relatively high 9.6:1 compression ratio.
Although our pre-production test machine was supplied with spigot-mounted
carburetors, production units will be rubber mounted. Engineers incorporated
rubber mounts not to isolate the carbs from engine vibration but to stop engine
heat from being transmitted to the carbs in hot weather. The ignition advance
curve of the Nippondenso-made solid-state control unit, added in 1981, peaks
very suddenly at very low engine speed —it's not the slower advance of former
Bosch units. As a result, hot intake mixture causes the idle speed to rise
enough to advance the timing, which further increases the idle speed. Laverda
representatives report that the rubber mounting has cured this self-generated
racing idle, which was present in our machine.
The all-roller-bearing engine received a new oiling system. A high-volume
pump circulates large quantities of oil under very low pressure the way previous
models did, but the Jota has a new full-flow oil filter with a disposable
cartridge. The oil passes through a cooler on the frame's front downtubes.
The 1982 crankshaft is also new. The generator, secured by an Allen bolt
rather than a nut, is on the right, and Laverda lengthened the crank's left end
to mount the ignition triggers. Laverda has added an outrigger needle bearing at
the clutch to ensure that the triple-row chain is held in alignment. The starter
clutch, located on the crankshaft, keeps the starter motor's drive chain
disengaged except when cranking.
The sand-cast engine cases, already impressively massive, now have extra
ribbing. The clutch, altered to reduce a rattle when disengaged, runs under an
outer cover with sound-deadening ribs. These modifications help the Jota comply
with EPA noise regulations.
The clutch is now hydraulically actuated, the first clutch of this type we've
ever tried. The lever operates a master cylinder, and a fluid-coupling hose runs
to the slave cylinder in the engine side-cover. The hydraulics can be
retrofitted to earlier 750 models, Mirages and Jotas.
An important alteration in the electrical system has provided much greater
right-hand cornering clearance. A new, smaller Nippondenso three-phase
alternator with increased output replaces the Bosch unit. In the switch,
ignition triggers were moved to the left-hand side, as noted above. Engine width
has been reduced about two inches on the right without affecting left-side
clearance. Extremely aggressive riders can grind the cases, but only after
passing the safe-riding threshold.
Though big, the Jota has a fairly compact seating position. The high and
narrow pegs are close to the seat; the relatively narrow tank provides tuck-in
room for the knees; and the low bars require a short stretch across the tank.
The seat height is remarkable—nearly three feet above blacktop level.Those with
shorter-than-average legs will haveadifficult time maneuvering tight quarters at
For our staff's preferences, the Jota handlebar was too low and too far
forward for long-term comfort. The wind would help keep the rider's weight off
his hands and arms, but the fairing breaks up this onrushing support. The ride
isn't windless, however; the air-stream coming off the bubble catches the rider
at mid-helmet. The bar, though short, is adjustable for angle. In terms of
controllability, the bar is good since the rider can get weight on it, even
though it provides little leverage.
The Jota's short, narrow, hard seat drew the ire of every staffer who spent
more than an hour on it. It's far too hard for normal American riders. The
seat's upward slope toward the gas tank prevents riders, especially short ones,
from sliding forward enough to take the load off arms and wrists. The semi-solo
does let the rider stretch, but it restricts passengers to little more than a
quasi-comfortable short hop. The 1200 Mirage seat is offered as an option at no
Footpeg and seat positions situate the rider's center of gravity directly
over the pegs. This allows the rider to move around easily. That's a Good Thing
because the bike with its tall profile, heavy steering and short handlebar needs
lots of power-assist from the rider to initiate cornering.
At frisky speeds on twisty roads the Jota's slow and heavy steering response
demands full concentration—the rider must initiate turning early enough to lock
the motorcycle on the desired line. As one staffer insisted, if a rider doesn't
know how to countersteer he'll learn or miss the corner. Once it's on lock, the
Jota has confidence-inspiring stability. Dips and bumps don't upset the Jota's
steadiness; any deviation from an established line in the middle of a corner
requires deliberate, forceful inputs.
Our Jota's front tire—a 4.00H x 18 Pirelli Gordon—added to the bike's
strenuously deliberate steering. The Gordon is an excellent all-around tire,
giving a nice combination of traction and wear qualities at the expense of heavy
steering. Jotas roll out of Laverda's factory with three possible sets of tires:
The mix is about 50 percent Dunlop TT100 and 50 percent Pirelli; half the
Pirellis are Gordons, half Phantoms.
Our sources at Laverda claim the Jota steers considerably lighter with the
100/90V x 18 ribbed Phantom. Our experience with these tires on other
motorcycles would substantiate this. The Phantom, however, doesn't have the
Gordon's large full-lean footprint and doesn't wear as well. Roger Slater, the
U.S. distributor for Laverda Motorcycles, points out that Laverda dealers will
install the standard tires of the rider's choice at no extra charge.
The air-charged, remote-reservoir rear shocks, new for '82, with five spring
preload adjustments, have non-adjustable damping. Although the fork is likewise
non-adjustable, the Marzocchi suspension controls wheel movement very well under
a variety of conditions, providing excellent road-holding and a reasonable ride.
The fork has some stiction, and the ride at the rear is moderately firm for
riders over 140 pounds. In this respect, heavier riders will be the happier
"Jota" (pronounced "Hohta," for the uninitiated) is the name of an old
Spanish gypsy dance in which one romps gaily in rapid triple time. This Italian
motorcycle version, with its triple cylinders, does its own vibro-jitterbug.
Buzzing is present at nearly every engine speed. Most intrusive is the handlebar
vibration. Our test Jota had its crankpins set at 180 degrees two up, one down.
Laverda has built 120-degree triples, with the crank-pins set in even intervals,
and we would imagine the interest in 120-degree cranks relates to the present
motorcycle's propensity for shaking.
The Brembo front brakes on our test machine required heavy lever pressure.
Nonetheless, sheer stopping power was very good enough to squeal the enormous
4.00-section front tire.
New aluminum carriers mate to Brem-bo's premium lightened rotors and replace
the old integral disc carriers. The components reduce unsprung weight,
significantly easing the task of the suspension units.
The hydraulic clutch lever should be a paragon of lightness, at least in
theory. But, strangely, the lever pull was extremely heavy, and the hydraulics
seemed to obscure the exact take-up point for engagement/disengagement. These
high pull-pressures, together with the engine vibrations, make riding the Jota
long distances wearisome.
The engine has a lot of low-end punch and it pulls eagerly right off idle.
Throttle response is good. At 6000 rpm the engine begins to make power with real
authority and carries strongly to redline. Yet the Jota is deceptive. The power
feels incapable of Superbike acceleration, but keep the tachometer needle
elevated and you'll see the scenery around you back up in a hurry.
It's possible that the Jota can make more horsepower than it actually did on
our dyno, where a combination of too-hot spark plugs and too-rich carburetion
hurt upper-rpm power figures. Since we were supplied with an incorrect primary
gear ratio, our dyno-calculated rpm figures proved four percent high—the engine
produced a maximum horsepower reading of 78.16 at 7690 rpm, well below the
engine's 8500-rpm redline. However, we run engines on the dyno until power
begins to fade or, in the case of the Jota, until misfiring begins.
Incidentally, the Jota clocked its 11.9-second quarter under the same conditions
in which it ran at the dyno.
The Jota comes equipped with two very tidy rearview mirrors that mount to the
fairing. You'll not see them in the accompanying photographs. Sadly, the mirrors
fell victim to the Jota's hurried schedule. First it was rushed to Cycle
for road-test photography, then carted off to an endurance race where it
crashed, and finally after much attention returned to the magazine for a road
test. We never saw the tool kit, but we're told it is very complete. Moto
Laverda went to great efforts to produce a new rider's handbook especially for
the American market. The tool kit fits into an under-seat tray and the handbook
can be carried in the storage area in the seat's tail-section, which, like the
tool tray, is accessible by lifting the hinged and lockable seat.
On balance the Laverda Jota is a narrow-spectrum motorcycle, aimed at the
sporting set whose predilections run to things Italian, and who insist Europeans
know best. For example, they won't find and wouldn't want a sidestand to hinder
cornering clearance or a digital-readout dashboard to distract them. The Jota
has real ground clearance, high-effort rider-input requirements, locomotive
cornering stability, a race-type seating and, perhaps most important, enough
muscle to be a genuine Superbike.

HAVE YOU EVER felt like a spare tit in the back row
of the local cinema? That's what it's like having the BMW K100RS in a hot-?hot,
rip-snorting, balls-out..ultimate sportster comparison test. Everyone around you
is dribbling and drooling and twiddling away at the preload doo-dahs, damping
wotsits and air valves, and you're sat there wondering how to get in a quick 200
leagues without arriving back in Douglas after 37 and a bit miles.
Yup, there was a whole lotta gruntin' going on (good grief) but the BMW wasn't
going any of it. Instead, it was more or less whiling away the time until the
long ride home when it could set tie down to its rather different stride and
really down come into its own.
'It's not a sportster,' said Mac, returning the keys after one lap. His tone was
that of a man whose lamb has turned out to be mutton. But I like it.'There spoke
a man who knew that the man who signed his expenses claims liked the RS too.
We'd met up the night before in Heysham. Mac and Dave, on the F) and Ninja,
looked slightly shagged after a day at Cadwell and a hectic ride trying to get
the most from the two multis. I'd come up on the BMW from London, getting a lot
of what was on offer, but felt slightly fitter since the RS's best is
comparatively further south of the redline.
Arriving on the Island the next morning, we'd watched practice at Quarter
Bridge, then gone for the traditional lap before breakfast. Somewhere between
Braddan and Ballacraine I realised that, were it not for the fact that Mac was
toting a nervous pillion, plus occasional hold-ups from the odd meandering
course-learner's tranny, the RS and mo/wouldn't be in the line up come
It wasn't just that the RS, although faster and tauter compared to its twin pot
predecessor, isn't as fast and agile as the three Jap bikes (and neither am I as
fast and agile as Brown or McDiarmid), but its long legged comfort and
easy-going, slow-rewing motor simply didn't kindle any manic desire to stay with
That is, of course, the way BMW planned it. In fact, they planned it so well
that the Bee Em's main reaction to being expected to hustle like a FJ or GPz is
a big Does Not Compute.
Hardly surprising really. Whereas the Laverda, Yamaha and Kawasaki have short,
stiffly-sprung suspension at both ends, the BMW has a comparatively whopping
7.3in up front and more average 4.3in at the rear. The springs up front are
fairly soft — so soft I forgot about several bumps on my way to work until I
borrowed the Ninja.
So if the BMW is braked down hard into a corner in the way the others are
designed to do, it goes in with its nose way too low, rear end way too high and
waggling on its shaft. The result is undignified in the extreme, although not
especially likely to cause anyone to fall off.
The way to do it is to get all your braking over and done with before peeling
off, select either of the two appropriate gears (torquey motor), chose round
about the right line (some leeway here, though not much) and power through. By
this time the Ninja is definitely winning the race, although I calculate that
even if it managed the Mountain 20mph faster than the RS (say the Ninja
maintains an easy 90mph average), its rider would have just two minutes to get
to the bar and buy you a drink.
It wasn't that the BMW wasn't at home on the TT course (it was doing a sight
better than the Kawasaki Z1000RI went up on last year), but that it and the
three Japs were in entirely different ball games. The accent with the FJ, GPz
and VF is on high horses.
explosive powerbands and lightning-quick, taut responses; the BMW is all about a
comparatively understressed motor in an over-engineered chassis with the accent
on long distance comfort even if it means trading off a measure of
Its motor puts out about 90bhp/litre (claimed), while the GPz needs nearly
130/litre to maintain its winning ways, and while none of the other fours could
be accused of gutlessness at low rpm, they can't quite match the feel of the
RS's slightly undersquare motor as it rolls you smoothly forward from less than
1500rpm in top. The BMW's flat torque curve and relatively compact revband
(redlined at 8500rpm) also make early upswaps and all-day 80-110mph riding
pleasurable enough to reserve exploration of the last 2000rpm for the enlivening
blast to 130mph or more.
Oddly unless Bayerischethink is already winning you over — the RS has by
far the best high speed riding position and protection. Funny how the Japanese
went to all that trouble to develop 16in front wheels to reduce steering effort
and frontal area on racers and then stuck, ugly great, high, wide bars on their
roadsters. Only the Kawasaki has a set of reasonably low bars to take advantage
The RS's narrow bars tuck you down nicely behind the fairing without stretching
your body across the tank, while the well-placed foolrests put some weight,
which'd otherwise rest on your bum, on your legs. The fairing is pretty
excellent. Wind and flies still hit your helmet but there's no question of a
stiff neck. Aerodynamically. the increased downthrust induced by the fairing and
slow steering geometry make the RS unbelievably stable at speed.
Naturally there's a trade-off in the form of pretty heavy steering at
progressive rates, especially since the short bars don't offer much leverage. If
you don't like that, sir, may we suggest the K100RT...
The more I rode the RS, the more impressed I became with the purposefulness with
which the whole plot was designed. Few riders would fault the suspension unless
they were chasing one of the other test bikes; many would welcome its compliance
and the need to adjust only a single, three-way preload ring on the rear shock.
Aside from its wonderfully clean lines (parked next to the VF it looks like an
aeroplane next to a Christmas tree), it also shows much evidence of careful
thought; such as the flip switch for quick headlamp adjustment to compensate for
a passenger or luggage.
It's not totally insipid or Teutonically dull, however. A secondary vibration
period around 3000rpm is occasionally annoying since it buzzes the left footrest
at motorway speed in top but hardly rates the added complication of a balancer.
The insistent hiss from the fuel pump in the tank has to be lived with, as does
a lot of cammy whirring which detracts from the motor's relaxed feel by making
it sound as if its turning faster than it is. All the KlOO's I've ridden have
occasionally muffed the first-second upshift, although the clutch is wonderfully
light and smooth and gear-changes become quicker and more positive as revs rise.
But the real joke isn't the silencer (which looks like a case of deliberately
leaving room for improvement) but the pillion arrangements. What, nograbrail?
Words fail me.
With the Jota dying, the only remaining rival to tempt me away from the Bee-Em
was the Ninja — mainly because it, too, displays the same singleminded intent
and unwillingness to compromise. In fact it'sso good it's awesome but since I
don't need to go that fast, I can't be bothered to put up with the harshness
while riding at under l00mph so I'll be very boring and start saving for the
'All the stuff's there to make one outrageous
motorcycle but somewhere in Honda's
design shop there's a wet willy'
JUST AS I WAS contemplating my notes about the Honda VFIOOOF and the wet,
nightmarish ride I'd had back from Heysham, a photo and caption in one of the
weeklies caught my eye. It had pop star Buster Bloodvessel astride some bike at
an obscure motorcycle show. The caption went along the lines of 'I like British
bikes because they're real machines. I don't like bikes which look like the
inside of a fridge.' He meant Jap bikes, of course.
Forgetting all the merits of new technology etc, he had a point. Look at the
Honda's instrument panel and you'll see neat gauges surrounded by anti-glare
matt black, flanked by the brilliant white of the half-fairing. Everything is so
unobtrusive, efficient, clean and functional that, yes, it could be an offshoot
of Zanussi. Open the filler cap and, sorry, no a little light doesn't come on...
Looks are subjective though and I'll leave It's all of the 'functional is best'
school of thought and the Honda is certainly the most comfortable of the three
Jap sports bikes among this collection. It's not as racy as either the Kawasaki
or Yamaha, but not as Mr Solid Upright Citizen as the BMW RS. Look at the Honda
from any angle and it's taller, slimmer, more 'ordinary' than the Kawasaki or
Yamaha. Certainly, when you first sit on it you notice the extra ride height
over those two bikes.
The riding position is reflected in its handling, as you'd expect, but only at
the very extremes of the perforamnce envelope of these'bikes. Back off from
those limits just a fraction and the Honda is one helluva good all-round bike.
When I was first allocated the Honda to test, I was a bi t miffed thinking, as
did most of us, that it was a good third in the excitement stakes behind the
Kawa and Yam (the Jota had by this time expired, Dellorto Rest Its Cams). I'd
ridden the Kawasaki up the IoM via Cadwell Park where I'd watched Mac get left
on the line in his classic bike championship race, thus losing the title, and
covered half of England at a ferocious rate. How's this overblown 750 gonna
compete with that? I thought.
Better that I'd imagined, came the strong reply. Round the Island's bumps the
Honda occasionally shook its head a bit wildly. RB claimed it almost threw him
off along one lane that he took at llOmph when the rest of us equipped with the
power of imagination rode at 80 max. It never got that bad for me.
Then the final piece of evidence came on that ride
back. Problems with Jota meant for odd reasons that I finally set out from
Heysham at 2am into the slooshing rain, more than a little fatigued and
bleary-eyed after three days revelry and bike-biasing. The Honda motored through
the buffeting storm, sending out a scorcher of a main beam to pick out the M6
lanes and roadwork cones. It was a shock to cut down to dip beam with its flat
topped beam. Take a tip from Cibie, Honda and light up the nearside edge...
After a few stops at service areas, none of which seem to be open on the south
bound side at that hour, dawn broke just as I left the motorway and cut across
country to Peterborough, my neck of the woods these days. The fatigue etched
into my eyes and bones lifted a bit with drying roads and some light and 1 wound
up the gas a bit. The Honda's best point came flooding through — its motor.
Hardly a gearchange was required on the 60 milc-stretch across Northamptonshire,
just blast, lean, blast, occasional brake.
The motor is a bored and stroked version of the VF750 rather than a cutdown 1100
V4. It's been achieved with some neat touches: to allow for the wider bores in
basically the same alloy block, the steel liners are now pressed in with the
coolant running directly against the outside of the liner. This is what's called
a 'wet' liner and is similar to the Gl V900K. The bore is now 77mm diameter, the
stroke increased by 5mm to 53.6mm giving an actual capacity of °°8cc. Con-rods,
big and small ends have all been strenthencd.
Bigger. 36mm Keihin carbs breathe through larger valves, bigger airbox and
exhaust pipes. Cams have more lift and duration while the VF750's bugbear — some
would say Honda's perennial nightmare — the cam chain has been changed to a
straighforward roller chain from the Morse type. Tappet adjustment is by
screw-and-locknut. Transmission is much the same as the 750 retaining the odd
one-way clutch to help prevent the back wheel locking up when changing gear
downwards. The clutch has two extra plates to cope with the extra poke, and the
gear ratios altered slightly to take advantage of greater low rev torque. At
lOOmph. the VF1000 is showing 6800rpm.
Oil capacity and the rate at which the coolant is pumped around the mill is
upped too though it's still possible to get the Honda near the read zone in slow
town use. In fact, our bike nigh on boiled over at the end of the test but it
had developed a small leak from the cover of the waterpump. The VF1000 uses the
left lower frame cradle to transfer water to the engine, one of Honda's neat
Chassis is smaller to the 750s, and bears a passing resemblance to the Yamaha's,
not considering the FJ's wrap round steering head. It's an advantage being steel
rather than alloy one prang and an alloy frame is usually bent. The engine
sits a couple of inches lower in the frame than the VF though it's still higher
overall than the others tested here. Nevertheless, it's a fine and easy handling
bike with none of the Yamaha's odd characteristics which split the test team
almost evenly. At least we all agreed about theVF.
It s the motor which sets the Honda on a pedestal t hough: power rushes in
gloriously at all revs above 4000rpm, and it's no slouch below either. While the
Kawasaki requires you to grab a lower cog for sharp overtaking, the Honda will
sing away with its distinctive rumbling. Around the TT circuit that's a real
plus if you're not as familiar with it as Mac. for instance. Fools rush in — but
not in the Isle of Man unless they're Roland Brown. The Honda allowed you to go
through a corner allowing room to manoeuvre and you could always count on the
The power delivery suits the nature of the suspension and relaxed feel of the
riding posit ion. Forks are 41 mm diameter wit h a three-position rebound
damping adjuster sat on top of the right leg. while the left leg has twice as
much compression damping as the right. Linking the two together is an air
assistance system and that rigid fork brace. There's a fair range of adjustment
up front and also on the rear Pro-Link shock. For total balls to the hurricane
riding round a bumpy circuit such as the TT course, the Honda is a shade soft or
at least wallowing but back on normal UK roads these traits are almost
impossible to find.
It's bad points are hard to find apart from the front brake. Jumping off the
Yamaha or Kawasaki onto the Honda was heart-stopping at first. The Honda's front
brake looks trick enough: twin piston calipers with a mechanical anti-dive. But
the feel is spongy and lacks bite until you've got the lever some way back to
the bar. It works well enough then but is way behind the others in the
The bodywork is well, okay if you fridges. It all fits together well, nothing
gets in the way but it lacks the aggressive poise of the Ninja and the
practicality of the BMW RSor the Jota. That half fairing knocks a sufficient
hole in the wind for °0mph cruising in comfort but this is a bike with 145mph
Over l00mph, it's neck stretch and wrist ache time
Summing up, I've got to say this is A Typical Honda. All the stuff's there to
make one outrageous motorcycle, just as Kawasaki have done with the GPz900R.
Corporate responsibility, conscience, no backbone, call it what you like but
somewhere in Honda's design dept they've got a wet willy. Shake him out, willya7
'The Laverda makes a
wonderful change from
the other bikes soulless
REMEMBER — take it easy, okay 7' I shouted to Mac as he put his helmet on and
threw an oversuited leg over the quietly idling Yamaha. He nodded and set off up
the ferry's slippery ramp towards land, tail light glimmering brightly through
the driving midnight rain. I fiddled with the Laverda's bar-mounted choke lever,
thumbed the starter button, gave the motor a few gentle blips and took a deep
breath before nosing the ailing Jota into he blackness of the downpour.
For a worrying moment 1 was left limping at the back of the queue, powerless to
keep up if the others suddenly sped off; then Dave dropped back and I was safe.
I needn't have worried: a few minutes later, on the outskirts of Heysham, the
Laverda suddenly slowed with a death rattle that even Brecon, well ahead on the
BMW. heard all too clearly.
We's been planning to call the RAC out ifrom Blackpool but this was terminal and
we had no choice.
The Jota was eventually trailered back to Three Cross Motorcycles to find out
the full extent of the disaster. A tangled valve had dropped off onto the
piston, damaging the barrels, bending a conrod and wrecking the crankshaft.
Comprehensively Donald Ducked, to borrow their phrase.
Three Cross couldn't understand it, because the bike had taken 15,000 miles of
hard use without complaint before we picked it up. We couldn't understand it
either, because the Laverda had begun running badly on almost the first occasion
I'd opened it up. The Jota had done no more than stumble round for a couple of
painfully slow laps once I'd nursed it to the Island, which was a great shame
because if any European machine could have challenged the new breed of Oriental
bulletbike then this was surely the one.
The latest Jota model represents the performance pinnacle of Laverda's
development of the famous aircooled triples. It takes the later, RGS-style
chassis with its bendable Bayflex bodywork and dresses it up with an all-new
fibreglass twinheadlamp fairing, sensibly cut back now to reveal the beautiful
sand-cast engine (early versions of the bike wore a full fairing; both styles
are available). The lines are sleek, the colour is a traditional orange and the
paint scheme isloud, very loud.
Into that set-up fits one of the later, 120-degree crankshaft engines
incorporating, in the case of our bike, a tuning kit that adds £500 to the
four-grand price tag of the basic machine. This provides a pair of
heavy-breathing 4C cams as fitted to the lovely but short-lived 120 Jota; forged
pistons borrowed from the Corsa to give a 10.5:1 compression ratio; a gas-flowed
and ported cylinder head and a modified airbox with jets to suit. The raucous
black three-into-one racepipe fitted to the testbike is officially not for road
use. Three Cross said, but the pipe costs a shade under £200 if you, er, don't
ride on the road, know wot I mean, John? It too is loud, very loud indeed.
After the soulless mechanical whirrings of the other four bikes the Laverda
makes a wonderful change with its barely-subdued rumble at tickover and its
fruity rasp when you blip the throttle. First impressions were good — the bike
started easily and felt low, light and manoeuvrable as I left the Three Cross
emporium in deepest Dorset and headed along the south coast on the M27.
At a nervous 85-odd mph the Laverda ambled along feeling like a man-eating tiger
on a very weak lead I had to fight hard to resist giving it a handful of
throttle that would probably have been disastrous for my licence, the more so
because, annoyingly, the bike had no mirrors and I couldn't read the speedo.
This was calibrated in kph, with illegibly small mph
figures inside, and was obscured from my view by the fairing's swept-back
screen. At leas that detail is only a problem if you're tall, unlike the awkWard
twin fuel taps and the horrible only-style Suzuki switchgear. On one occasion I
managed the old favourite of blacking all the lights out when trying to use the
dipswitch. . .
On the move the bike has that distinctively taut, Italian feel to it — even
without the noise you'd have no problem picking it out blindfold. The riding
position stretches you out over that big orange tank and the twistgrip has a
long action needing a big grab to get the Dellortos fully open and gulping. The
hydraulic clutch is still fairly heavy and although the gearchange is positive
it has a long travel and needs a forceful foot.
The Brembo brakes are excellent in the dry, almost
as good as the Kawasaki's discs, but they're not quite as immediate in the wet
at low speeds.
If the Lav was losing time on the Island's straights during its brief blast,
then it sure wasn't giving much away in the corners. Not so long ago a front and
rear Marzocchi setup was the only way to go if you wanted to get a big bike
round the 1 1 course at a respectable rate without bouncing off numerous walls
and hedges on the way. And although the Japanese have changed all that and the
Laverda's steering is heavy by comparison, you won't find a much more stable
perch from which to observe lesser bikes' suspension shortcomings than the
narrow black seat (complete with removable tailpiece) of the Jota.
The hefty, non-adjustable Marzocchis up front are just as you'd expect:
decidedly firm for everyday use but strong, well-damped and great for attacking
the mountain at silly speeds. Rear shocks are remote-reservoir units that seem
almost crude by modern standards but which let you know exactly what's going on
at the road surface below. With the five-way preload on its minimum setting the
ride was well-controlled without being uncomfortably harsh and the Laverda had a
reassuringly solid feel in fast bends. Pirelli Phantoms are the normal tyre
fitment but our bike was shod with a pair of the new Avon Super Venoms, which
gave no nasty moments.
If only its engine had held together the Jota would have been so at home on the
Island. The 981cc two-valve triple has to be taken to a heady state of tune to
stay in the performance game these days but the rubber-mounted, 120-degree motor
remains a beaut. As you wind open the throttle the Jota lurches forward with a
bellow, then as the tacho reaches seven grand the exhaust note changes its
pitch, the bike leaps onward again and you're heading for the top speed of a
shade over 140mph.
Although the motor likes to be revved there's a reasonable amount of midrange
The only glitches are fuel consumption that often
drops below 30mpg and a dodgy spot at around 2500rpm (apparently that's where
the ignition advance comes in) which results in some very erratic behaviour if
you try riding along at that speed in town. Apart from that the motor's as
flexible and well-mannered as you could hope for from such a fire-breathing old
warhorse. If only we'd had more chance to let it show its paces.
Kawasaki GPz 900R
'It was the red and grey
Kawasaki that everyone
felt happiest on when the
going got tough'
THE NINJA came out of the open Waterworks right-hander like a rocket, front end
hardly twitching as it recrossed the white line while still cranked over they
screamed off up the hill. As the tight, walled and straw-baled bends outside
Ramsey disappeared in its mirrors to be replaced by the fences, the panoramic
views, the fast, often-blind curves and the sheer drops of the mountain the
Kawasaki seemed to suck in even more of the warm early-evening air and to puff
out its chest with pride. The Ninja was back on home ground: undisputed King of
It was not so much the Kawasaki's sheer speed that got to everyone who rode it.
though that was impressive enough. More important is the way the GPz copes with
that speed and puts the rider in perfect control at alltimes. It'ssingleminded
toa degree normally seen only in Italian bikes: the riding position is long and
low; the suspension is firm and heavily damped; the brakes are phenomenally
powerful and it takes six tightly-spaced gears to keep the high-revving motor on
the boil at all times. It'sa Japanese Jota of abike, as Dave Calderwood hinted
in his test in July's issue, and it makes the FJl 100 and the VFIOOOF look
almost soft by comparison.
Take the riding position, for example. It brings the rider forward to reach the
swept-back two-piece handlebars and for pottering round town it's less
comfortable than the more upright stance given by the Honda and the Yam.
Combined with stiff forks the low, narrow bars give your wrists a tough time and
at slow speeds the steering is relatively heavy.
But when you're following a motoring McDiarmid into the Laurel Bank section,
peering over the fly-spattered screen as the hedges and walls flash past,
frantically trying to remember which way the next bend goes and how tight and
bumpy it's going to be, there's just no better pair of handlebars to be holding
on to. At speed the Ninja's steering and handling are quite superb if what
you thought was lefthander suddenly heads off to the right a slight nudge is all
that is needed to put the Kawasaki on a different line, and once it's there it
sticks to that line like a 119 horsepower Manx tram to its rails.
In every aspect of fast cornering the GPz900 is precise, stable and
confidence-inspiring. Hit a bump at well over a ton on the mountain and the
Ninja shakes its head a little, then at once settles down again without any
fuss. On one incredibly bumpy stretch of road going towards Jurby Airfield the
Honda got into a nasty high-speed tankslapper (the only time 1 got it to
misbehave seriously, I should add); when I went back over the same bit of road
on the Kawasaki its bars got very lively but there was no need to slow down.
It's a shame the Yamaha wasn't on form, it might have run the Ninja close, but
it was the red and grey Kawasaki that everyone felt happiest on when the going
Another reason tor that were the brakes, which are as good as any I can remember
using. The front discs are incredibly powerful, needing only light pressure on
the lever, as well as being very progressive and controllable. The Kawasaki has
little of the FJll's tendency to stand up when braking into bends, and with its
powerful AVDS anti-dive system the Ninja retains a wonderfully stable front end
to encourage you to squeal the front Japlop right into corners.
There's a fair bit of jarring through the bars whichever of its three positions
the anti-dive is set on. and the same goes for the fork air pressure.
Recommended settings vary between 5psi and ail of 8psi; I preferred the higher
limit and was happier with the 21psi maximum in the rear shock and the four-way
damping turned up, which helped when it came to carrying a passenger. Like the
older GPzs' the Ninja's shock adjustment is a screwdriver turn away, behind a
sidepanel, so altering settings is a time-consuming business.
When you're riding the Kawasaki it's hard to believe that its 908cc motor is
giving away a significant number of cubes to all its competitors. The
watercooled four-valver lacks the midrange punch of some, true, but it's a great
engine: silky, narrow and very, very powerful. Keep it above 6000rpm and the
Ninja responds instantly to the throttle, and even below that figure it runs
cleanly and is noticeably less peaky than the most recent two-valveGPzllOO
It's also very smooth, thanks largely to the gear-driven balancer shaft situated
directly beneath the crank. This turns backWards at twice crankshaft speed and
neutralises the engine's tingling secondary vibration, which in turn allows the
power unit to be solidly mounted and to act as a stressed member of the
skinny-looking but obviously immensely strong frame. Very little vibration gets
through to the rider, even when you make use of the real megapower lying between
eight grand and thel0,500rpm redline.
That sort of power band means plenty of hoofing around through the
thoughtfully-provided six-speed gearbox but even when barrelling round the
Island's ribbon of blind bends I rarely found cog-swapping a problem. Like the
rest of the bike the Ninja's gearchange seems to work best when the going is
fast: round town, changes tend to be clonky but at high revs you can flick up
and down instantly and the lever action is so sweet you need hardly give it a
thought. Only dodgy part of the transmission is the
clutch — our original testbike's unit gave up completely at MIRA and the second
bike's clutch was obviously poorly after just a few gentle half-mile runs. One
slow, juddering and shrieking launch produced a best-ever (wind-assisted) 11.13
second quarter so I packed up and went home while the going was good.
There were a few other niggles: a slight oil weep from the camchain tensioner
region (the Hy-Vo camchain runs up the left side of themotor; the alternator
sits behind the engine and is chain-driven from the right of thecrank); a leak
that meant the coolant tank had to be topped up on a few occasions; and the
failure of the temperature gauge on the last day of the test. More general
faults were mostly related to ergonomics. The fairing provides no hand
protection and its mirrors are too close together; the indicator switch is basic
and the dipswitch is small. On the plus side the grabrail is strong and the
retractable bungee hooks make luggage carrying easy unless you're two-up (which
is often when you most need it, of course).
It would hardly be stretching a point to say that on a bike such as this we
should be grateful for any concessions to practicality we're given — after all
the Jota has no mirrors at all. But when the opposition is as hot as the Ninja's
is Kawasaki can't afford to slip up on even the slightest detail. For superquick
roadwork the Yamaha, especially, is so close behind that it's the rider who'll
make either bike the quicker over most twisty roads, and theFJllOO's extra
midrange, greater comfort and better detail work tempt me to pick it as my
favourite. Then I remember my last, fast Island lap on the Ninja — the uncanny
stability as it banked through the Bungalow, the awesome speed as it flew down
the hill towards the Creg. And once again I'm not so sure...
'Mean looking and low. I the Yamaha offers promise
and delivers—in spades'
GET ONE OF THESE and you'd better recalibrate your
diary. It took at least a week's custody of the FJ1100 before I got the hang of
not arriving for appointments half-a-county away at least a pint ahead of
schedule: you just aim in the general direction of your destination and delight
in getting obviously lost, secure in the knowledge that the Yamaha will get you
from anywhere to almost anywhere else in less time than you've got.
And about time, too. Until now Yamaha's range of big four-strokes has brought
them to the verge of financial collapse and the rest of us adrenalin cold
turkey, particularly those allergic to mainlining on two-strokes. Their range
lacked overall pzazz and a flagship in particular: the FJ is both — and right up
there with the best.
Mean-looking and low, the 1100 offers a promise and delivers — in spades. The
compact four-valve, twin-cam motor pulls smoothly in any gear from 1500rpm, then
starts to burn serious rubber from 6000 to the redline at 9500rpm. Although peak
torque arrives as late as 8000rpm, the mill, puts out above a healthy 50
foot-pounds all the way from 3500rpm to the redline; for comparison a Ducati
900SS peaks close to that figure. Coupled with impeccably clean carburation and
instant throttle response, this makes for gusty acceleration at practically any
revs in any gear. Equally crucial, the power band is progressive and predicable.
Just as well — with horses well into three figures on the leash, abrupt delivery
would offer nowt but gravel rash.
Compared with the GPz and VF, the FJ has appreciably more mid-range than the
Kawasaki, less sheer bottom-end but marginally better extreme top-end than the
Honda. In a top gear roll-on from 70mph against that all-time king of grunt, the
Yamaha XS11, the FJ initially lost 20 yards or so before resoundingly clearing
off above 1 lOmph; stir those slick gears a little and the XS might as well be a
pony trap. Without the pony.
Considering the amount of stomp on tap the FJ is commendably frugal, averaging
42.9mpg overall. The low of 37.3 was guzzled two-up with luggage on fast
A-roads, arriving dead on time after a mileage under-estimated by 50 per cent;
the high of 52.9 was at night on unfamiliar B-roads into a blizzard of midges,
but otherwise without especial restraint. Full-tank range is upwards of 180
miles, the reliable fuel warning light coming on about 20 before this. There is
no reserve and the fuel gauge is a waste of space.
The FJ is equally civilised off the forecourt. Mechanical noise is limited to
muted valve-train chatter and transmission whine. That, eerily, is all there is
to be heard on the overrun. The exhaust is all but inaudible. Even after the
most brutal caning the tickover settles to a steady whirr, and the motor fires
on the button cold, hot or very hot. Astonishing, when you consider that this
sort of specific power was close to the limit of technical development only 20
But if the FJ didn't handle on a par with all this magnificent clout, you could
stick it in your ear. Fortunately it does. Despite a temptation to dismiss the
'lateral concept' frame as so much Japspeak, it appears as rigid as any more
conventional cradle; also offering exceptional maintenance access and looking
trick into the bargain. The bike steers with real precision at all speeds, save
with a slight tendency towards understeer on slow corners where really huge
bumps can also make it sit up.
Yamaha has made the most of 16-inch front wheel technology (the similar diameter
rear is neither here nor there, and is anyway so fat-tyred as to have a
'conventional' rolling radius): there are 18-inchers which steer as quickly, but
at the price of highspeed instability. The quick steering characteristics of the
small wheel have allowed Yamaha to employ lazy steering geometry — the yoke
offset, for instance, is distinctly Ducati — without the pentalty of advance
application, in writing, for direction changes. In addition the designers went
to considerable trouble to keep the engine as short as a typical 650cc
transverse four; the resulting short wheelbase also contributes to responsive
steering: the FJ is nearly three inches shorter than other Japanese 1100s.
For its size the FJ changes line rapidly and with a minimum of rider input,
impressively so at very high speeds. It readily chops line on corners where
lesser bikes are committed to one and accepts quite heavy front brake deep into
turns. Overall it's rather less agile than the lighter but equally solid GPz and
slightly slower steering but more stable than the VF. All three, though, bring a
new dimension into the combination of power with handling.
Unfortunately some of the FJ's precision goes out to lunch as the
original-equipment rear boot gets clapped. Grippy these Japlops may be, but they
become increasingly prone to white-lining and high-speed weave. To put this in
perspective it never became remotely alarming or occurred within hailing
distance of UK speed limits; it's just there.
This tendency could be dialled out in part by upping
rear suspension settings and completely vanishes with new rubber. It's probably
worth experimenting with the various alternative tyres available: one reliable
source claims Pirelli Phantoms are the answer.
Suspension both ends is multi-adjustable for damping and preload, although the
correct alien key for the forks would be a welcome addition to the tool kit.
(Not everyone has a GPz on hand for this purpose.) Ride is supple and compliant
even on the hardest settings, although to my mind the monoshock is both slightly
under-damped and under-sprung. The forks are substantially braced and with the
anti-dive set close to minimum I couldn't fault their action.
The brakes are superb, powerful, progressive and full of feedback. Although
they give slight best to the Kawasaki, they're light years ahead of the Honda's,
which faded with surprising ease. Early anti-dive Yams had a sponginess from
pumping up the fork hydraulics, but the FJ has no such problem. Leverage ratios
at the rear are ideal: even the clumsiest boot, of which I have two, is unlikely
to lock the wheel.
Grounding anything but the fold-up footpegs is strictly for nutters and heroes,
who'll probably also want to ditch the centre-stand which scrapes under extreme
duress. Said citizens will also appreciate the TV-size mirrors to admire their
trails of sparks, and incidentally to keep an eye on the Old Bill. All they're
likely to find behind that slippery fairing, if they ever catch you, is a grin.
The rest of your development will already have been arrested.
WITH the notable exception of the Honda, all five bikes lived up to
expectations. The most expensive — the BMW at £4495 —
doesn't of fer the performance and handling brilliance of the cheapest — the
GPz900R at £3199 — but justifies its high price in terms of equipment, finish,
reliability and remarkable longdistance comfort.
The Laverda, at £3999 basic (£500 more with the
tuning bits), comes closer to the Japanese bikes' performance but depends
largely on subjective appeal and its Italian heritage. Apart from the RGS Corsa,
it's the best non-Japanese musclebike around-Making a choice between the three

All offer more poke than anyone seriously needs, excellent handling, and price
tags to make European sales directors weep. In the end it was lack of startling
virtues, rather than any major vices, which relegated the VF1000F to third
place. It was just too. . . nice. The FJ1100 looked at first to be a big threat
to the Ninja, with more povrer and greater potential as an ultra quick
Ultimately, however, everyone voted for the Kawasaki. Over £300 cheaper than the
Honda or Yam, it equals or betters both as a street racer, has superb brakes,
and always feels more exciting. Which is surely what a sports motorcycle is all
about. If it wasn't for the BMW and Laverda, picking the Ninja as overall winner
would be easy. But few could dispute the KlOORS's ability to live up to its
maker's promise. Nor is the Jota the worse off for Laverda's refusal to totally
sanitise their products: quite the opposite. All three are winners, although if
you've always reckoned that cheapest is best, Kawasaki have proved that the
best, for once, is also the cheapest.
