Renthal 2027 Honda CRF450 5240-520 Twinring Rear Sprocket - Black 48T

Renthal Twinring motocross rear sprocket was developed as the ultimate dirt bike rear sprocket for those looking to ride more and work less. The unique, dual-material design combines a hardened steel outer chain ring that is heated to 200 degree C before being permanently fitted to our Ultralight aluminum inner, creating a permanent bond for the life of the sprocket.
