M12 x 1.25 Flanged Lock Nut

A replacement M12x1.25 Flanged lock nut for 150cc and 250cc vehicles.

This lock nut is an exact replacement for the lock nuts holding the variator fan plate and clutch bell in the GY6 CVT system, as well as many, many other locations throughout the vehicle frame on 150cc and 250cc buggies.

This nut also fits the clutch bell shaft on the CN250 and CF250 engines. It will not fit the variator shaft on CF250 buggy motors. The correct nut for the variator shaft on those engines is the M14 nut.

Make sure to check for the correct size before ordering.

This nut is not vehicle specific and can be used in a vast number of other applications.
