Manufacturer Ref: 1211-822-42-10 — Brand: MOOSE OFFROAD HARD - PARTS
Aluminium rear sprocket designed to replace the original sprocket on 520 pitch transmissions. Machined 100% (without stamping or grinding), this sprocket features optimised tooth thickness to ensure maximum contact between the tooth and the chain, limiting premature wear due to poor profile. Subtle and durable black finish, suitable for both off-road machines and urban roadsters.
Designed for Trail/Adventure, Enduro, Cross, Supermoto, Trial, Quad, Roadster, and Sport/Racing environments. Particularly suitable for models that demand durability and precise engagement. Common fits include: GAS‑GAS EC 300 RACING (2017), SHERCO SEF‑R 450 (2015), and BETA RR 350 (2014).
Replace your worn sprocket with this machined part to restore clean chain engagement and predictable transmission behaviour. Check compatibility with your model and chain alignment before installation.
