Moose Offroad Hard-Parts — Rear Sprocket 51 Teeth (Pitch 520)
Designed for enduro and motocross riders, this rear sprocket combines lightness and strength. The inner ring made of 7075-T6 aluminium reduces weight compared to a fully steel sprocket, while the outer ring made of reinforced steel ensures the necessary resistance against wear and shocks from the terrain. The self-cleaning grooves between each tooth limit mud accumulation for smoother transmission on muddy terrains.
Ideal for off-road applications, this sprocket is designed to last while reducing unsprung mass. It is suitable for motorcycles equipped with a 520 pitch transmission and a compatible rear sprocket — common examples include: YZ 450 F (2021), YZ 450 F Monster Energy Racing Edition (2021), or XR 250 R (ME06). Standard installation and maintenance: check chain slack and alignment during replacement to ensure optimal longevity.
