Moose Racing Rear Sprocket, 45-Tooth Aluminum, Blue for Husaberg, Husqvarna and KTM (1211-897-45-12)

Upgrade your motorcycle’s final-drive performance with the Moose Offroad 1211-897-45-12 rear sprocket. Designed for select Husaberg, Husqvarna and KTM applications, this 45-tooth sprocket is manufactured from 7075-T651 aluminum for a strong, lightweight solution suited to demanding off-road riding. Its blue finish adds a clean, race-inspired appearance while maintaining the functional design expected from Moose Offroad drivetrain components.
The 7075-T651 aluminum receives an additional tempering process that helps reduce distortion and supports consistent sprocket performance. Compared with typically thinner 7075-T6 sprockets, the optimized thickness provides a durable balance of strength and weight. This construction helps the sprocket withstand repeated acceleration, impacts and changing trail conditions while supporting reliable chain engagement.
Each Moose Offroad 1211-897-45-12 sprocket is 100% machined rather than stamped or ground. Precision machining produces an accurate tooth profile and helps maintain uniform contact between the sprocket teeth and drive chain. The optimized tooth thickness promotes maximum tooth and chain contact, supporting smooth power transfer and helping reduce uneven wear throughout the drivetrain.
For riders seeking a dependable replacement or performance-focused upgrade, this Moose Offroad rear sprocket delivers application-specific fitment, lightweight aluminum construction and carefully controlled manufacturing. Verify your motorcycle’s year, model and original drivetrain specifications before installation to confirm compatibility with the 45-tooth configuration.
