Universal Fitment - This 420 chain sprocket kit replaces used parts on 50cc to 125cc motors.

Accurately Engineered - The front sprocket is 0.235 inches thick with center holes 1.18 inches apart, compatible with 17mm motor countershafts for a secure, dependable installation on mini machines and go karts.
