-

1986-87 VFR750F (G, H) All-new model: aluminium-alloy beam frame, 748cc (70x48.6mm) liquid-cooled 90º V4 engine with 180-deg crankshaft, centre gear-driven DOHC, 16 valves, 105bhp at 10,500rpm. 16in and 18in wheels with TRAC anti-dive 37mm forks. Dry weight 199kg.

1990 VFR750F-L Complete chassis redesign with shorter wheelbase, revised steering geometry and new aluminium alloy frame incorporat­ing subframe and single-sided ‘Pro-arm’ swingarm replacing convention­al rear fork. Wheels now 3.5x17in and 5.5x17in, and 41mm front fork improved. Revised cylinder heads with bucket-and-shim valve actuation. Dry weight 216kg.

1994-97 VFR750F (R,S, T,V) Complete chassis redesign with new aluminium-alloy beam frame and all-red bodywork with styling similar to the ovalpiston­ed NR750. Lightening of frame, wheels (including narrower 5.0in rear rim), front fork, single-sided swingarm and ancillary items is said to cut weight by seven kg to 209kg. Carbs reduced to 34mm and exhaust retuned for better response.

2002-2013 VFR800 V-TEC Most significan­t change with restyled bodywork and 782cc engine incorporat­ing V-TEC, or system for operating just one of the two inlet valves for each cylinder below 6800rpm to improve low-end torque. Cam drive reverts to chain. Exhaust system revised with fashionabl­e but impractica­l twin silencers under the seat. Fuel tank capacity increased and four bulbs used in headlamps. 1988-89 VFR750F (J, K) Wheels changed to 17in front and rear. Fork leg diameter upped from 37mm to 41mm. Fairing altered from two-part to three-part assembly along with two-position screen and faired-in turn signals. Only change to engine is updated ignition. Instrument panel includes fuel gauge and clock.

1992 VFR750F-M Cosmetic alteration­s to bodywork. Engine retuned with different cam timing and a larger silencer to improve top-end power. Front fork redesign with cartridge internals.

1993 VFR750F-N Cosmetic changes including white wheels matched with white bodywork in some markets.

1998-2001 VFR800FI Complete ground-up redesign with fuelinject­ed engine derived from the RC45 racer featuring 782cc (72 x 48mm) capacity and side-mounted gear cam drive and novel aluminium alloy frame bolted to top of crankcases, the single-sided swingarm pivoting on the rear of the gearbox. Side-mounted radiators. Dual combined braking system and restyled wheels.

2014-on VFR800F Complete redesign again that continues today with more subdued Italian-influenced styling, exhaust system reverted to convention­al four-into-one position. Adjustable seat height. Shift assist clutch. Traction control. Power of the 782cc engine still peaks at 105bhp but dry weight is still 242kg.
