Moose Offroad Hard Rear Sprocket - Parts (ref. 1211-BET-51-13)
Rear sprocket made of aluminium designed for the enduro rider seeking precision and reliability on all terrains. Manufactured from 7075 T651 aluminium with additional heat treatment, this sprocket reduces the risk of deformation while maintaining a tooth thickness superior to common 7075 T6 parts. Machined 100% (no stamping or grinding), it offers a consistent tooth profile and controlled geometry for clean chain engagement.
The machined design ensures an optimised tooth thickness for maximum contact between the tooth and the chain, useful in muddy or rocky conditions where every link counts. Compatible mounting on enduro setups and machines suited for the 520 pitch and the specified number of teeth. Product photo provided for reference.
Common compatibilities: BETA RR 480 EFI Racing (2018), BETA RR 430 EFI (2018), BETA RR 390 EFI (2018).
