Moose Offroad Hard Rear Sprocket - Parts — manufacturer reference: 1211-822-50-10
7075 T651 aluminium rear sprocket specially machined for fitting on a 520 pitch transmission. This black 50-tooth part is made 100% by machining, without stamping or grinding, to achieve precise geometry and optimised tooth thickness. The additional heat treatment applied to the 7075 T651 limits deformation and ensures a consistent thickness compared to the usually thinner 7075 T6 sprockets.
Designed for off-road and road use — enduro, trail/adventure, motocross, supermoto, roadster, sports, urban, and quad — this sprocket will fit machines such as GAS‑GAS EC 300 RACING, SHERCO SEF‑R 450, or HUSQVARNA NUDA 900 R. Its precise machining optimises the tooth/chain contact for consistent transmission behaviour while providing a robust solution for replacements and setups. Ideal for demanding riders looking for a reliable aftermarket part sized for the 520 pitch.
