Rear crown made of aluminium by MOOSE OFFROAD HARD - PARTS, designed for Enduro and Cross practices. Manufactured from 7075 T651 alloy with additional heat treatment, this crown limits deformation and has a suitable thickness compared to the thinner 7075 T6 parts. Machined 100% (without stamping or grinding), it features a tooth profile whose thickness is optimised for maximum contact between the tooth and the chain.
Machined part for precise fitting and consistent tooth geometry, tailored to the needs of riders on demanding terrains. Compatible with many enduro/cross models — for example, YAMAHA YZ 450 F Monster Energy Racing Edition (2021), HONDA XR 250 R (ME06) (1989), or YAMAHA YZ 450 F (2021) — it is aimed at riders looking for a lightweight rear crown, correctly sized and ready to be mounted on a 520 pitch drivetrain.
