1992 Honda NSR250-SP MC21-1068897. SP version = top specification with dry-clutch and other uprated components. This example has 4925 km (3053 mi) showing on the odometer.

Starts right up and runs and rides well. Looks good with light corrosion on aluminum as well as fairing stays / shift linkage / chain.

Very rare bike that’s suitable for collector or rider but owner should understand & service to their own standards (inspection / tires / fluids / crank seals).

From NSR World – History

Unveiled in late 1989 as a new 1990 model, the MC21 took the 2-stroke world bu storm, and completely re-wrote the rule book on how.a 250 2-stroke should be built. The craftsmanship was superb, and the new features were groundbreaking! The mC21 now utilized PGM-III ECU (also being utilized in GP250 by official HRC Factory nSR’s). Coupled to throttle position & gear position sensors, the PGM-Iii controls controls the timing of the RC Valves, air correctors and ignition advance to give outstanding low end tractability. The PGM-III features a true 3D ignition and a different map for each cylinder.

In keeping with their racer for the road image, the famous Gull-Arm rear swinger was copied from the factory NSR250 of Luca Cadalora, as well as the frame design.
