Rear sprocket (crown) by MOOSE OFFROAD HARD - PARTS, manufacturer reference 1211-897-51-12. Designed for Offroad and Supermoto practices, this aluminium crown is intended for Enduro, Cross, Quad, and Supermoto machines where engagement precision and geometric stability are essential.
The disc is fully machined from aluminium 7075 T651 with an additional heat treatment, which reduces deformation and ensures an optimal tooth thickness compared to the usually thinner 7075 T6 parts. Machined 100%, without stamping or grinding, the tooth profile aims for maximum contact between the tooth and chain for a clean and consistent engagement.
This crown is suitable for users looking for a precisely machined rear drive component for their off-road or on-road supermoto sessions. Compatible motorcycle examples: KTM EXC-F 500 Sixdays (2023), HUSQVARNA FE 450 (2023), GAS-GAS MC 350 F (2023).
