Moose Offroad Hard Rear Sprocket / Crown - Parts: an aluminium crown designed for the final drive of off-road and road motorcycles. Fully machined, it combines 7075 T651 aluminium with an additional heat treatment to limit deformation and maintain stable geometry over time. The design prioritises an optimal tooth thickness to ensure precise contact between the tooth and the chain, a key element for a clean and play-free transmission.
Designed for Trail/Adventure, Enduro, Cross, Supermoto, Trial, Roadster, Quad, and urban use, this crown is suitable for configurations where transmission reliability is paramount. Examples of frequently fitted motorcycles: GAS-GAS EC 300 RACING (2017), SHERCO SEF-R 450 (2015), BETA RR 350 (2014). Ideal for riders looking for a lightweight, durable part with an 'off-road' look accentuated by its red finish.
