Moose Offroad Hard Rear Sprocket - Parts designed for enduro and motocross riders looking for a robust component without adding weight to their bike. This bi-material sprocket combines a 7075-T6 aluminium inner ring with a reinforced steel outer ring: the construction limits weight where it matters while providing the durability of the teeth against impacts and terrain abrasion.
Designed to last longer than some standard aluminium rear sprockets and remain significantly lighter than a fully steel component, this sprocket is aimed at rides on muddy, stony, or dusty terrains. Its tooth profile and grooves facilitate mud evacuation for smoother operation and simplified maintenance after sessions.
Ideal for enduro and motocross machines (e.g. YAMAHA YZ 450 F 2026, YZ 125 2026, YZ 450 F Monster Energy Racing Edition 2025). Manufacturer reference: 1210-251-48-12X.
