Then the more restrictive rules came in and Honda had to start with a production bike rather than a prototype. Hence the RVF750R (RC45) was developed with an all new engine.
First the RVF prototype then production RVF750
Mr.Honda, the consummate engineer, never waived from his dream of
racing a 4 stroke designed by his employees built solely under the
roof of his Japanese factory... he petitioned the ruling bodies to
allow 750cc 4 strokes to compete with the 500cc 2 strokes... so under
his command HRC designed the RVF750 to be 85% Gp machines for its
respective period... the Old Man understood that if his plan to fill
the dwindling Gp grids with his RVF works 4 stroke machines fell short
he would undoubtable produce one soundly competitive WSBK machine...
From 1990 on Mick Doohan and Wayne Gardner had a direct input in the
development of the RVF750 works machines... If you want know what a
Honda 750 4 stroke Gp racer feels like then the RC45 is for you...
Shame that Honda called the RC45 an RVF though rather than keep it as a VFR,
Mercy not a shame because according to HRC the RC30 engine is a modified street design hence VFR750R whereas the RC45 is a totally fresh designed hence RVF750...
