Honda NSR500

The Honda NSR500 is a race motorcycle from the Honda NSR series. It was 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 present, six in a row 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.

Honda NSR125

The Honda NSR125 is a 2 stroke, 125 cc (lightweight) sport bike produced between 1988 and 2001. The high revving (red zone of the tachometer begins at 11,000 rpm), 2 stroke, RC-Valve equipped, single-cylinder engine produced around 30 bhp (22 kW) at the crank. The name is taken from the NSR 500 GP bike which proved great success on the track.

History and Development

There were 2 models of the NSR125; A JC20 produced between 1988 and 1994 and the JC22 "Foxeye" produced between 1994 and 2001. They are easily distinguished by the headlights. JC20 has double round headlight. The JC22 has a "foxeye" headlight hence the nickname.

Following the success of the NS125(an earlier model to the NSR), the NSR125-JC20 was designed and assembled by Honda Italia Industriale S.P.A. in Rome, Italy. Grimeca was contracted to produce the Alcast frame (2-piece, die-cast, bolt together construction), wheels and brake assemblies. The engine was manufactured by Girardoni with Dellorto equipping the carburetor. Marzochi supplied forks and suspension while Pagani provided instrumentation and lighting. The Grimeca rear wheel was 18", front 17" and shod in Pirelli MT-45 tires.
