Rear sprocket made of MOOSE OFFROAD HARD - PARTS aluminium, designed to replace the original part on 520 transmissions. Manufactured from aluminium 7075 T651 with additional heat treatment, it limits deformation while maintaining an optimal tooth thickness compared to the thinner 7075 T6 versions. 100% machined (without stamping or grinding), this sprocket offers a worked tooth profile for maximum contact between tooth and chain.
Ideal for trail, enduro, motocross, supermoto, roadster, or quad riders, this sprocket is aimed at motorcyclists looking for a lightweight and precise part for their transmission. Full machining and optimised tooth profile ensure consistent geometry for regular chain engagement in all conditions.
Examples of commonly compatible models: GAS‑GAS EC 300 RACING (2017), SHERCO SEF‑R 450 (2015), HUSQVARNA NUDA 900 R ABS (2013). Always check the pitch and number of teeth before installation.
