Moose Offroad Hard-Parts Rear Sprocket – Manufacturer Ref: 1210-822-48-13X. 520 rear sprocket designed for motorcycle transmissions, intended for demanding trail, enduro, motocross, supermoto, and roadster/urban use.
This sprocket features a "dual" design: a 7075-T6 aluminium ring to reduce weight and a steel crown for wear resistance. The self-cleaning groove between each tooth limits the accumulation of mud and dirt, making it practical for off-road use. Compared to fully aluminium crowns, this solution offers a longer lifespan while remaining lighter than solid steel.
Ideal for riders who ride both on trails and in the city, it fits 520 transmissions and is suitable for Trail/Adventure, Enduro, Motocross, Supermoto, and urban applications. Examples of applications: GAS‑GAS EC 300 RACING (2017), SHERCO SEF‑R 450 (2015), HUSQVARNA NUDA 900 R ABS (2013). Please check the exact compatibility with your model and chain configuration before installation.
