Moose Offroad Hard - Rear Sprocket (manufacturer's ref: 1211-822-50-12)
Aluminium 520 rear sprocket, designed for demanding off-road transmissions as well as on-road. 100% machined (no stamping or grinding), it uses 7075 T651 aluminium with an additional heat treatment: a finish that reduces deformation and allows for optimal tooth thickness compared to thinner 7075 T6 sprockets. The tooth thickness has been designed to maximize contact between the tooth and chain, ensuring smooth drive and predictable transmission behaviour.
Ideal for riders practicing trail/adventure, enduro, motocross, supermoto, as well as for roadsters and urban use. Compatible with many machines (e.g. GAS-GAS EC 300 Racing 2017, SHERCO SEF-R 450 2015, HUSQVARNA Nuda 900 R 2013). Replace your rear sprocket with a machined and stable component for a reliable chain-sprocket connection and consistent performance, regardless of the terrain.
