Moose Racing Rear Sprocket, 49 Tooth for Yamaha (1211-853-49-12)

Upgrade your Yamaha drivetrain with the Moose Offroad 1211-853-49-12 rear sprocket, engineered for dependable performance and long-lasting service. Manufactured from 7075-T651 aluminum, this sprocket receives an additional tempering process that helps reduce distortion while maintaining an optimized balance of strength and weight. Its carefully controlled material properties provide a durable alternative to thinner 7075-T6 sprockets.
The Moose Offroad rear sprocket is 100% machined for accurate tooth geometry and consistent fitment. Unlike stamped or ground sprockets, its fully machined construction supports precise chain engagement and reliable power transfer. The optimized tooth thickness increases contact between the sprocket teeth and chain, helping promote smooth operation and durable drivetrain performance during demanding riding conditions.
Designed for Yamaha applications, the 49-tooth configuration provides a practical replacement or gearing option for riders seeking a quality component from a trusted off-road brand. The Moose Offroad 1211-853-49-12 combines precision manufacturing, heat-treated 7075-T651 aluminum, and optimized tooth design in a lightweight rear sprocket built for recreational, trail, and performance-focused use.
