The Honda NSR500 is a road racing motorcycle created by HRC (Honda Racing Corporation) and debuted in 1984 for the Grand Prix motorcycle racing's 500 cc class. Honda won ten 500cc World Championships with the NSR500 from 1984 to 2002, with six in a row from 1994 to 1999. With more than 100 wins to its credit, the NSR500 is the most dominant force in modern Grand Prix motorcycle racing. The 1989 NSR500 that won Honda's third 500 World Championship with Eddie Lawson exemplifies the overwhelming power, acceleration and raw speed that has always been synonymous with Honda's 500 cc two-stroke V4. 1984–1987 Designed to succeed Honda's first two-stroke Grand Prix racer, the NS500 triple, NSR500 debuted in 1984 for the Grand Prix motorcycle racing's 500 cc class. Building on lessons learned from its three-cylinder predecessor, the new V4 used a single crankshaft, making it lighter and more compact than its dual-crankshaft adversaries. Though tormented by unorthodox chassis technology in its first season, the NSR500 evolved to clinch Honda's second 500 cc GP title in 1985. Opening the V-angle to 112 degrees in 1987 made room for a quartet of 36 mm Keihin carburetors between the cylinders where they could be fed more cool air. The new arrangement also let the engine exhale more efficiently through its four artfully intertwined expansion chambers. By year's end, Honda won a third 500 World Championship with Australian rider Wayne Gardner. 1988–1989 Entirely redesigned for 1988, the NSR500 got a stiffer, twin-spar aluminium chassis and various engine changes. The changes made to the 1988 bike made it somewhat problematic for the riders, especially in the first half of the season. Wayne Gardner had a hard time in defence of his 1987 World Championship and although he eventually got on top of the bike's problems and won three races in a row in mid-season (Dutch TT, Belgium and Yugoslavia), he could only finish second in the championship behind the Yamaha of Eddie Lawson. The main complaints about the 1988 NSR500 was that the engine, while undoubtedly the most powerful in 500cc racing, was very 'peaky' and had to run up high in the rev range to get the best out of it. Also the suspension geometry of the bike wasn't as good as in 1987 and the bike was noticeably harder to handle through the turns than the rival Yamaha YZR500 and Suzuki's new RGV500.
