Ducati 996R
Derived from racing bikes that have been consistently winning WSB championships since WSB began, the first Ducati Superbike, the 851, was launched in 1987, this bike was followed with the 888, 916, 748 and the 996. The 916 won several worldwide awards including 4 “Motorcycle of the Year” awards from MCN magazine. The 996 replaced the 916 in 1998. An entry into the legend of Italian motorcycling racing, an aggressive, high performance and beautifully designed machines, closely derived from Ducati’s currently competing in the WSB. Aimed at purists who want everything from a bike with its compact design and slim silhouette to provide superior handling at speeds up to 170 mph. Combines advanced thermodynamics of 4-valve per cylinder with unsurpassed efficiency of Desmodromic valve system. Smaller, lighter, sealed-for-life battery
It's the most expensive bike currently
available in Oz - and one of the fastest. But is Ducati's 996R really worth
$52,000? SHEEPISH ADMISSION But the 996R is one such bike. In fact when I returned the testbike to Moto
One's dealer principal Tony Barton he sheepishly admitted the same thing had
happened to him. Except in Tony's case he found himself still riding around
at two in the morning! The 996R's peak output in homologated
guise is a claimed 135ps at 10,200rpm at the crankshaft - 13ps more at
200rpm less than the 996SPS. AMCN got around 130ps at the R's rear wheel on
the PTR dyno, which may not seem much compared to some of the 1000cc Jap
fours which have 10ps more and are also some $30K cheaper! Yes, that much.
LESS TEETH Short-shifting at around 7500rpm
underlines how excellent the spread of power is. For street use though I'd
be inclined to swap the 15-tooth countershaft sprocket for a 14T item.
Standard gearing sees an indicated 3200rpm at 100km/h, meaning the R is
geared for well over 320km/h out of the box. The smaller sprocket would make
the bike smoother around town (the R is already substantially smoother than
the longer-stroke SPS) as well as boost acceleration. To create the 996R, Ducati focused most
attention on the new engine, and slotted it into the same tubular-steel
spaceframe as the SPS - itself derived from Foggy's racebike.
Fully-adjustable 43mm Öhlins race forks as used on the Ducati Superbikes are
fitted, with gold titanium-nitride coated stanchions to reduce stiction, and
a race-quality, multi-adjustable Öhlins shock. But the 996R is one of those bikes which
is much more than just the sum of its parts. Yeah, I can hear the cries now:
"Not another bloody Ducati test"; or "No bike is worth that much"; and so
on... What can't be denied though is that a model that was introduced back
in 1994, eight years ago, still sets the standard for sportsbike design.
Testa Tech Inside Ducati's hottest desmoquattro DUCATI'S FORMER CHIEF ENGINEER, Massimo Bordi, was at pains to stress that the Testastretta is a case of EVOlution over rEVOlution. Says Bordi,"While it's in every way a completely new engine which shares scarcely a single part with any of its predecessors, the Testastretta has its roots firmly set in our established desmoquattro heritage. Same thing with a nondesmo, valve-spring engine," continues Bordi."Every time Porsche tries to change its Boxer engine layout, nobody buys it.. .well, it's the same for Ducati—and that's why we opted for EVOlution, not rEVOlution, in developing the Testastretta." That explains why various alternative formats for the new-generation Ducati superbike engine were all discarded— such as any nondesmo variations, narrower-angle vees and revised layouts for a 90-degree format with the cylinders rotated backWard on the crankcase in order to reduce the overall length of the engine as on the Honda Rtbl . Ditto lot gear-driven cams or even pneumatically (and especially electro magnetically) operated valve gear that many see as the future of high-performance, four-stroke motorcycles. So the major change for the Testastretta
engine is to the cylinder heads, the design of which (in a departure from
established Ducati tradition) was subcontracted to an outside consultant:
retired Ferrari design engineer Angiolino Marchetti, who died soon after
completing The Marchetti designed heads have a freer-breathing 25-degree valve angle (it was 40 degrees before) and service 2mm bigger cylinder bores; the measurements are 100.0mm bore and 63.5mm stroke compared with 98.0 x 66.0mm from the 996SPS. Flatter combustion chambers permit the use of oversized valves (inlets are now 40mm, up from 36mm, and exhausts are 33mm, instead of 30mm), and though compression is unchanged at 11.5:1 in street With a shallower combustion chamber and straighter, freer-breathing ports, the Testastretta would appear to have horsepower potential in droves. The smaller cambox (left) displays new cam plain bearings (in lieu of roller elements) and makes the engine more compact but required a complete rethink of its desmoquattro dynamics. guise, there's now extra space for that to be increased in pursuit of more power. The bigger pistons are actually lighter
than their narrower predecessors. This meant . Marchetti had to completely : revamp Bordi's previous design, which featured the opening, finger-type rockers positioned directly above the closing, forked rockers inboard of the camshafts. The new layout positions the opening cam followers outward to the front and rear edges of each cambox; all rockers and followers are substantially smaller and lighter than before. Car-type valve covers open to reveal camshafts belt driven as before but now rotating directly in plain metal bearings instead of the previous (heavy, bulky) roller bearings. The Testastretta features a single,
centrally positioned, external spray injector per cylinder for its Marelli
EFI, upstream of (4mm-larger) 54mm throttle bodies with elliptical chokes.
They are controlled by an ultracompact, new-generation Marelli ECU.
Marchetti's straighter, steeper downdraft porting sees the mixture get a
much cleaner hit at the valves, improving both power and efficiency.
