Renthal Twinring benefit from over 50 years of motocross rear sprocket manufacturing expertise and the help of our top Off-Road and Enduro factory race teams, Renthal has developed 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°C before being permanently fitted to our Ultralight aluminum inner, creating a permanent bond for the life of the sprocket. The result is a lightweight, long-wearing rear sprocket fit to tackle any condition you can find, without adding unnecessary unsprung weight and compromising power delivery.
