Honda RS750R

The Honda RS750R was a competition motorcycle that Honda produced in 1984 to race in the Formula TT and Endurance championships. It uses a four-stroke 750 cc V4 engine derived from the road-going VF 750F, while its aluminium perimeter frame was inspired by that of the NS 500 Grand Prix bike. It raced for a single season, 1984, in which it won both the TT-F1 World Championship and the Endurance World Championship, and it also won the Suzuka 8 Hours, where it filled every step of the podium. For 1984 the FIM cut the maximum displacement of four-stroke Formula 1 engines from 1000 cc to 750 cc, and Honda, which had used the RS850R until then, presented a widely revised machine with a closed double-cradle frame of square aluminium tubes. The 90 degree V4 keeps the 748 cc dimensions of the VF 750F, adds gear-driven camshafts, and gives 132 hp in F1 form and 120 hp for endurance racing.
