context_page_description: The Honda VFR750R, model code 'RC30', was a fully faired solo seat only racing motorcycle created for homologation purposes for the World Superbike Championship by Honda Racing Corporation. It was first released to the Japanese market in 1987, 1988 released in Europe then the United States in 1990. There were only 3,000 ever made and sold for $15,000 US - a very large amount for a production bike at the time.
context_section_description: The  748 cc 16-valve gear driven double overhead camshaft liquid-cooled RC24-derived 90° V4 produced 75.94 hp (56.63 kW) at 9,500 rpm for the restricted Japanese model and 118 hp (88 kW) @ 11,000 rpm elsewhere. It contained race-inspired components. These included such items as titanium connecting rods a first on a production bike that reduced reciprocating weight (50 g or 1.8 oz 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, when coupled to the close ratio gearbox which had an extremely high first gear ratio (0 - 82 mph), made the RC30 untouchable in terms of driveability when on the move. 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.
  It redlined at 12,500 rpm  (in comparison to the VFR750F which redlines at 11,000 rpm) and had a tested 1/4 mile time of 11.8 seconds.
