Moose Racing Beta Rear Sprocket 51-Tooth Black Aluminum (1211-BET-51-10)

Upgrade your Beta motorcycle’s final-drive performance with the Moose Offroad 1211-BET-51-10 rear sprocket. Manufactured from 7075 T651 aluminum, this black sprocket is designed to provide a strong, lightweight solution for demanding off-road riding. Its specialized tempering process helps reduce distortion while maintaining a more substantial tooth profile than many thinner 7075 T6 sprockets.
The Moose Offroad rear sprocket is 100% machined for precise, consistent construction. Unlike stamped or ground sprockets, its fully machined design supports accurate tooth geometry and dependable chain engagement. The optimized tooth thickness promotes maximum contact between the sprocket teeth and chain, helping deliver smooth power transfer and reliable performance across varied terrain.
Built specifically for Beta applications, this 51-tooth sprocket can help tailor gearing for improved low-speed control and stronger acceleration. The black finish adds a clean appearance while complementing a wide range of motorcycle builds. With its combination of 7075 T651 aluminum, precision machining, and optimized tooth design, the Moose Offroad 1211-BET-51-10 is a practical choice for riders seeking durable, responsive drivetrain performance.
