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.

Could this be the most advanced motorcycle on the planet? VTEC variable valve timing broadens the VFR800's power band, the high-tech PGM-FI electronic fuel injection ensures crisp throttle response while the catalytic convertor reduces emissions. The all-new 2002 VFR800 may be a sport tourer but it features technology that the competitors' superbikes will envy. And the 2002 model is the first VFR800 to offer available anti-lock brakes (VFR800FA).

Engine/Drivetrain
· Compact, 781cc DOHC 90 degree V-4 with an oversquare bore and stroke of 72mm x 48mm.
· Combustion chambers feature an 11.6:1 compression ratio and are fed by programmed fuel injection through short, straight intake ports.
· VTEC features hydraulically actuated lifter sleeves inside the inverted buckets of the valve train's direct-actuation lifters. Below 7,000 rpm only one intake and one exhaust valve are actuated. Above 7000 rpm, an oil spool valve, actuated by an electric solenoid, sends oil pressure to the lifter actuators and positions their spring-loaded engagement pins above the valve stems to initiate actuation of the remaining two valves of each cylinder. Precise, shim-under-bucket valve actuation for the two continuously operating valves contributes to quiet low-speed engine operation and allows 25,600-km valve maintenance intervals. The diagonally opposed VTEC-actuated valves utilize shimless buckets, reducing valve train weight and service complexity.
· The VFR's engine serves as a stressed member of the pivotless frame, which features specially designed engine mounting bolts tuned to work in harmony with the damping characteristics of the frame.
