Entraînement Pignon 12T NON O.E. ALTERNATIVE

This 12-tooth drive socket sits on the gearbox output shaft and takes the chain drive on many of Honda’s smaller engines. Over the years, the splines often wear or the teeth start to hook, especially on bikes that have done plenty of miles. Swapping it during a rebuild saves later trouble and keeps the final drive running true. The part follows the original layout, so it fits straight on without adjustment.

Used across many 50cc Honda models, including C50, Z50, MT50, MB50, and NSR50 variants.
