Moose Offroad Hard-Parts Rear Sprocket / Crown made from 7075 T651 aluminium, designed for enduro and motocross enthusiasts looking for a lightweight and precise component for their transmission. The 7075 T651 alloy benefits from an additional heat treatment that reduces deformation and allows for an optimal tooth thickness compared to the generally thinner 7075 T6 crowns. Machined 100%, this crown is produced without stamping or grinding, ensuring a clean finish and a uniform tooth profile that guarantees consistent contact with the chain.
Designed for rear mounting, this crown optimises chain/tooth contact thanks to a carefully studied tooth thickness, ideal for sustained attacks on trails or circuits. It naturally fits into gear configurations intended for enduro and motocross. Suitable for machines such as the HONDA CRF 450 R (2021), the RED MOTO CRF 250 RX Enduro Special (2020), and the BETA RR 480 EFI Racing (2018), as well as other models compatible with a 520 pitch of 53 teeth.
