Rear Sprocket – Aluminum or Steel


Precision CNC machined rear sprockets in hardened 7075T6 aluminum alloy or C49 High Carbon steel. Offered in stock 43 tooth count (and other sizes under special order*).

The aluminum sprocket has less unsprung weight without sacrificing durability. The steel sprocket exceeds the OEM sprocket life at a fraction of the OEM replacement cost.

(*) NOTE: Non-stock sprocket sizes may require adjustment in chain length and/or other modifications.  Special order only – call or email for availability.
