Moose Racing Dual Sprocket 51-Tooth Silver for Yamaha (1210-251-51-11X)

Upgrade your Yamaha drivetrain with the Moose Offroad Dual Sprocket, Part Number 1210-251-51-11X. Engineered to outlast standard aluminum rear sprockets, this dual-material design combines a lightweight 7075-T6 aluminum inner ring with a durable heavy-duty steel outer ring. The result is a strong, dependable rear sprocket that offers an excellent balance of reduced weight and long-lasting wear resistance for off-road riding.
The silver Moose Offroad Dual Sprocket is built to handle demanding terrain and repeated drivetrain loads. Its steel outer ring provides added durability at the tooth contact area, while the aluminum center helps keep overall sprocket weight lower than comparable steel alternatives. This construction supports responsive handling and reliable power transfer without sacrificing the rugged performance expected from an off-road component.
Self-cleaning mud grooves between each tooth help prevent dirt and debris from building up during rides in muddy or loose conditions. By helping clear contamination from the tooth profile, the grooves promote smoother chain engagement and help maintain consistent drivetrain performance. The 51-tooth configuration is designed for Yamaha applications requiring this specific rear sprocket setup. For proper fitment, verify your motorcycle model, year, chain size, and original equipment specifications before installation.
