MOOS OFFROAD HARD Rear Sprocket - PARTS (ref. 1211-897-50-10)
Rear crown made of aluminium, specially machined for off-road practices: enduro, motocross, quad and supermoto. Manufactured from 7075 T651 with additional heat treatment, this crown limits deformation and offers an optimised thickness compared to thinner 7075 T6 parts. The machining is done 100%: no stamping, no grinding, for a reliable and consistent tooth geometry.
Designed to withstand the demands of challenging terrains, this crown prioritises engagement precision and wear consistency thanks to fully machined manufacturing. Ideal for riders seeking a lightweight part without compromising dimensional stability.
Compatibility (examples): KTM EXC-F 500 Sixdays (2023), HUSQVARNA FE 450 (2023), GAS-GAS MC 350 F (2023).
