Moose Offroad 1211-822-45-13 Red 45T Aluminum Rear Sprocket — Beta Gas Gas Sherco

Moose Offroad — Aerospace-Grade 7075 T651 Aluminum, CNC Machined Precision, and Factory Red Styling

Reduce rotating mass and sharpen your bike's power delivery with the Moose Offroad 1211-822-45-13 Rear Aluminum Sprocket. Specifically engineered for Beta, Gas Gas, and Sherco off-road machines, this 45-tooth sprocket is the choice for riders looking for a lightweight drivetrain solution without compromising structural integrity. By utilizing premium 7075 T651 aluminum, Moose Offroad provides a sprocket that is significantly lighter than steel, enhancing suspension action and acceleration response.

Every Moose Offroad sprocket is 100% CNC-machined, ensuring a perfectly concentric part that eliminates the tight spots and vibration often found in stamped sprockets. The T651 tempering process provides an extra level of stability, resulting in an optimal thickness that resists distortion better than standard T6 aluminum. This precision tooth profile maximizes chain-to-sprocket contact, distributing the load evenly across the 520-size chain to extend the life of your drivetrain. Finished in a vibrant UV-resistant Red anodization, it adds a "Works" aesthetic to your rear wheel.

• 7075 T651 Aluminum Construction: High-strength aerospace aluminum with extra tempering for maximum durability and reduced distortion.
• 100% CNC Machined: Precision-cut teeth and mounting holes ensure a perfect fit and smooth rotation.
• 45-Tooth Gear Ratio: A versatile tooth count ideal for increasing top-end speed or stretching out gears on faster courses.
• Maximum Surface Contact: Engineered for optimal tooth thickness to provide the highest level of chain engagement.
• Factory Red Finish: High-quality anodization provides a striking look while resisting corrosion and fading.

Moto-House MX Pro Tip:

Aluminum rear sprockets are an excellent performance upgrade, but they require a fresh 520 chain for the best results. Running an old, worn chain on a new aluminum sprocket will cause "hooking" and premature tooth wear. When installing the Moose Offroad 1211-822-45-13, we recommend using new sprocket bolts and a drop of medium-strength thread locker to ensure everything stays tight under high-torque conditions. Regularly check your chain slack; a properly adjusted chain is essential to maximizing the service life of your high-performance aluminum sprocket.
