Rear sprocket / crown in MOOSE OFFROAD HARD - PARTS aluminium, designed for enduro and motocross practices. Made from 7075 T651 with additional heat treatment, this sprocket limits deformation and maintains an optimised tooth thickness compared to thinner 7075 T6 parts. Machined 100% (no stamping or grinding), it offers precise tooth geometry for maximum contact between the sprocket and the chain, ensuring consistent wear and performance on trails or tracks.
Ideal for riders looking for a robust and precise crown, it is particularly suited for motocross and enduro machines. Compatibility examples: HONDA CRF 450 R (2021), RED MOTO CRF 250 RX Enduro Special (2020), BETA RR 480 EFI Racing (2018). Standard 520 mounting — check the number of teeth and the spacing before installation.
