Rear Sprocket / Crown MOOSE OFFROAD HARD - PARTS (ref. 1211-897-50-11)
Designed for the transmission of demanding riders, this rear crown made of 7075 T651 aluminium offers a robust and precise construction for enduro, motocross, quad, and supermoto. The specific heat treatment of 7075 T651 reduces the tendency to deform and allows for a tooth thickness greater than that of thinner 7075 T6 parts. Full machining: made 100% by machining, without stamping or grinding, to ensure consistent geometry and precise contact with the chain.
Optimised tooth thickness for maximum contact between the tooth and the chain, ensuring even wear and reliability mile after mile. Ideal for replacing the original crown on recent machines such as the KTM EXC-F 500 Sixdays, Husqvarna FE 450, or GASGAS MC 350 F, as well as for any use on tracks and technical roads where robustness and transmission precision are essential.
