Rear sprocket made of aluminium specifically designed for 520 transmissions, by MOOSE OFFROAD HARD - PARTS. Fully machined from 7075 T651 aluminium and subjected to additional heat treatment, this sprocket limits deformation and features an optimised tooth thickness compared to standard 7075 T6 parts. The result: a tooth profile designed for maximum contact between the tooth and the chain, useful for off-road, enduro, motocross, trail, or supermoto use.
Designed for demanding riders who want precise and reliable equipment for their transmission, this sprocket easily integrates into 520 setups. It is particularly suited for modern motocross and enduro machines — notably the SUZUKI RM-Z 450 (2026), RM-Z 250 (2026), and RMX 450 Z (2019) — while remaining relevant for trails and supermoto conversions.
