MOOS OFFROAD HARD - PARTS Rear Sprocket — an aluminium crown designed for the demanding enduro and motocross rider. Made from 7075 T651 with additional heat treatment, this crown limits deformation and offers an optimised tooth thickness compared to thinner 7075 T6 parts. Machined 100% (without stamping or grinding), it provides a consistent tooth profile for maximum contact between the tooth and chain, ensuring controlled wear in off-road conditions.
Designed to withstand the demands of off-road riding, this crown is ideal for muddy outings and track sessions. Its full machining ensures precise tooth geometry, facilitating engagement and transmission efficiency. Check the 520 pitch and the number of teeth for compatibility with your model before installation.
Common compatibilities: Yamaha YZ 450 F Monster Energy Racing Edition (2021), Honda XR 250 R (ME06) (1989), Yamaha YZ 450 F (2021).
