Honda VFR750R

The Honda VFR750R, model code 'RC30', is a fully faired, solo-seat-only racing motorcycle created for homologation purposes for the World Superbike Championship by Honda Racing Corporation (HRC). It was first released to the Japanese market in 1987, released in Europe in 1988 then the United States in 1990. There were only 3,000 made and they sold for - a very large amount for a production bike at the time. Engine The 748 cc 16-valve gear driven double overhead camshaft liquid-cooled RC24-derived 90° V4 produced at 9,500 rpm for the restricted Japanese model and @ 11,000 rpm elsewhere. It contained race-inspired components. These included such items as titanium connecting rods that reduced reciprocating weight ( lighter and eight times the cost) and gear driven camshafts. The engine firing configuration was very different from the road-going VFR750F from which it was derived with a 360° 'big bang' crank arrangement instead of the smoother 180°. This feature produced a very broad spread of power and was coupled to the close ratio gearbox which had an extremely high first gear ratio (0 - 82 mph). Slowing down was made easier with a slipper clutch, and impressive braking capability for the era. While being inspired by the Honda RVF endurance racer (not to be confused with the Honda RVF750 RC45) the VFR750R instead had its engine based on the 1986-7 VFR750F (RC24). The engines are almost identical externally, the only visible differences being in the cylinder heads and the engine side covers. Inside the engine no major parts were identical to the RC24. The clutch, gearbox, crankshaft, oil pump, connecting rods, water pump, pistons, starter clutch, and the entire valvetrain and cylinder heads are specific to the RC30. There were race kits available from HRC Honda.
