Moose Offroad Hard Rear Sprocket - Parts (ref. 1211-822-49-11)
This rear sprocket made from 7075 T651 aluminium is designed for demanding riders seeking lightweight and precise tooth profiles without compromise. The material undergoes additional heat treatment to reduce deformation compared to the common 7075 T6 versions. Machined 100% (without stamping or grinding), it features an optimised tooth thickness for maximum contact between the tooth and the chain, ensuring smooth torque transmission.
Suitable for trail, enduro, motocross, supermoto, trials, roadster, sports bike, and quad practices, it fits many rolling chassis looking for a lightweight and well-machined sprocket. Specifically compatible with GAS-GAS EC 300 RACING (2017), SHERCO SEF-R 450 (2015), and BETA RR 350 (2014) models, subject to verification of pitch and bolt pattern.
Choose a robust sprocket designed for precise contact with the chain and predictable behaviour on the road or off-road. Manufacturer reference: 1211-822-49-11.
