The RVF750R was the successor to the VFR750R RC30. Like its predecessor, the RVF750R featured a DOHC liquid-cooled V4 4-stroke engine with gear driven cams and a single-sided swingarm, but unlike the RC30 it utilized electronic fuel injection, in a setup very similar to the production 1992 NR750. The US spec engine had a 749.2cc capacity and was rated at 101 horsepower; the European version was rated at 118 horsepower. A simple rewire modification to the PGM-FI box increased power in the US engine up to the 118 hp.
