Good To Know

Q: Does this kit fit all YZ125 models from 1986 to 1990? A: It is listed for the Yamaha YZ 125 across those model years, but running changes can affect fit. Verify your model year and serial number before ordering.

Q: Will new springs fix a slipping clutch? A: Fresh springs restore plate pressure and can cure slipping caused by weak springs. If the plates themselves are worn, replace them along with the springs for best results.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
