NOTE: This sprocket is made to bolt up to many 2000+ Harley Sportster & Big Twin rear wheels, however, the final fitment will be dependent upon many factors of your application, so please take measurements prior to making a purchase. If your bike is stock, you still may need to double check the offset against the front sprocket.

NOTE: Remember a larger rear sprocket means more torque (geared down) and a larger front sprocket means more top end (taller gearing).
