Honda VFR 800F V-Tec
The VFR800 inherited its position as class leader in the sports-touring sector from its 750cc predecessor. Although its roots go back to the first VF750 of 1982, the latest VFR800 is one of the most accomplished and advanced motorcycles produced. The V-4 engine at the heart of the VFR uses a VTEC variable valve system which alters the valve opening behaviour to give different power characteristics depending on engine speed. Below 7000rpm, only two of the four valves in each cylinder are opened by the camshafts. This two-valve layout gives superior torque and power production at low revs, where intake gas velocity is more important than large valve time-area values. But at higher revs (above 7000rpm) a computer-controlled valve pushes locking pins into place.
These pins engage the remaining two valves in each cylinder, and the engine takes on the characteristics of a four-valve design. The extra valve time-area is perfectly suited to high-speed power production. The VFR also features Honda's PGM-FI fuel-injection system, which boosts power, economy and clean-running, as well as a catalyzing element in the exhaust system to further reduce pollution. The chassis combines sporting ability with touring practicality. A 'sport' version of the CBS linked brakes gives a more suitable blend of stopping power front and rear, while an optional ABS braking system provides extra security on unpredictable
road surfaces. Adjustable 43mm (1.7in) front forks and the single-sided monoshock rear suspension give superbly damped handling, and while the VFR is heavier than many sportsbikes, it disguises the extra mass well once on the move. The broad dual seat is comfortable for many miles, even with a pillion, and the angular bodywork keeps the worst of the weather off. A generous 22-litre (4.8 gal) fuel tank, together with the efficient VTEC engine allows an impressive 322km (200 mile) range between refills. Optional accessories like hard luggage, heated grips and taller screens further enhance the VFR's touring ability.
Review
Those of you of a certain age will remember a
snooker player called Steve Davis. Nice guy, and very successful, but not
exactly what you would call an exciting player to watch. He just did the job,
very efficiently, and collected prizes. There was a photocopier company who used
him in their TV ads - "Boringly reliable copiers" was their tagline. The general
opinion, certainly among my esteemed colleagues in the motorcycle press, seems
to be that the VFR is the Steve Davis of motorbikes. Worthy and capable, yes,
but also rather dull. Not, I have to say, that the public found that to be a
problem. The VFR has always been a good seller here, perhaps because you, the
buying public, are more interested in getting something that will do what you
need rather than the latest fashion tool. Which is a good thing. Perhaps you
also remember Ron Haslam taking a totally standard VFR from a dealer and
acquitting himself extremely well at a very wet 1985 Transatlantic race weekend
at Donnington against full blown factory racers. Oh yes - the VFR may have been
dull and dependable but it has always been fast and been blessed with better
than average handling.
For the record, by the way, Honda cite the following
as the main reason behind fitting linked brakes: "The CBS system, in most
emergency situations, offers greater braking efficiency than a conventional
system. For example,a rider performs an emergency stop only using the front
brake lever. As the system is linked they will get some additional, and
proportional, braking force from the rear, without even thinking about it."
Well, it seems perfectly reasonable and certainly doesn't have any adverse
effects that I could find. If you can think of a downside, would you let me
know, please?
