Aluminium rear sprocket by MOOSE OFFROAD HARD - PARTS, designed for 520 transmissions. This sprocket utilises 7075 T651 aluminium with additional heat treatment to limit deformation and provide an optimised tooth thickness compared to the 7075 T6 versions. Fully machined (no stamping or grinding), it ensures precise tooth finishing for consistent contact with the chain.
Designed for demanding riders on both trails and roads, this sprocket is aimed at Trail/Adventure, Enduro, Cross, Supermoto, Trial, Quad, Urban, Roadster, and Sport/Racing practices. Its optimised tooth profile promotes maximum contact with the chain for uniform load and controlled wear. Suitable for models such as GAS-GAS EC 300 RACING (2017), SHERCO SEF‑R 450 (2015), and BETA RR 350 (2014) — please check compatibility with your setup before installation.
