Designed to succeed Honda first 2-stroke GrandPrix racer the NS500 triple that earned Honda first 500cc World Championship with Freddie Spencer in 1983 the Honda NSR500 debuted in 1985. Building on lessons learned from its 3-cylinder predecessor, the new V-4 used a single crankshaft, making it lighter and more compact than its dual-crankshaft adversaries. Though tormented by unorthodox chassis technology in its freshman season, the NSRevolved to clinch Honda second 500GP title in 1986. The new arrangement also let the engines exhale more efficiently through its four artfully intertwined expansion chambers.



More improvements gave Eddie Lawsons Honda NSR500 upwards of 166hp @12000rpm essentially doubling the output of Mike Hailwood`s 1967 Honda RC181 Grand Prix 4-stroke. Honda unveiled a revolutionary idea with a 1992 V4 that was timed to fire all 4-cylinders within 65-70 degrees of crankshaft rotation.



Along with a balance shaft that neutralized the single crankshaft engines gyroscopic effects, the 1992 Honda NSR 500 motorcycles was a breakthrough. Emphasizing acceleration over sheer speed, Doohan used the "big-bang" engine to win five of the first seven 500 GrandPrix races of 1992. Although a badly broken leg denied Doohan`s bid for the 1992 World-Championship, he would not be denied for long. Beginning in 1994, Doohan and the NSR won five consecutive 500cc World Championships.
