Moose Offroad 1211-822-47-12 Blue 47T Aluminum Rear Sprocket — Beta Gas Gas Sherco

Moose Offroad — Aerospace-Grade 7075 T651 Aluminum, CNC Machined Precision, and Performance Blue Anodization

Sharpen your machine's handling and acceleration by reducing rotating mass with the Moose Offroad 1211-822-47-12 Rear Aluminum Sprocket. Engineered for the demanding hub patterns of Beta, Gas Gas, and Sherco off-road motorcycles, this 47-tooth sprocket is the choice for riders who want to fine-tune their gearing while shedding unsprung weight. By utilizing premium 7075 T651 aluminum, Moose Offroad provides a sprocket that allows your rear suspension to react faster to technical trail obstacles, providing a more "flickable" feel in the woods or on the track.

Every Moose Offroad sprocket is 100% CNC-machined, ensuring a perfectly concentric part that eliminates the vibration and tight spots common in stamped alternatives. The T651 tempering process provides an extra level of structural stability and thickness, resisting distortion better than standard T6 aluminum sprockets. This precision-cut tooth profile maximizes contact with your 520 chain, spreading torque loads evenly to prevent premature wear. Finished in a high-quality, UV-resistant Blue anodization, it adds a striking "Works" aesthetic to your bike that resists fading and corrosion.

• 7075 T651 Aluminum: Aerospace-grade alloy with extra tempering for superior thickness, strength, and resistance to distortion.
• 100% CNC Machined: Precision-cut for perfect concentricity and smooth power transfer without the imperfections of stamping.
• 47-Tooth Profile: A versatile gear count ideal for riders looking for a balance between punchy acceleration and high-speed efficiency.
• Optimal Surface Contact: Engineered tooth thickness results in maximum chain-to-tooth contact for increased drivetrain longevity.
• Anodized Blue Finish: High-quality coating protects against the elements while delivering a professional racing appearance.

Moto-House MX Pro Tip:

Reducing unsprung weight is one of the most effective ways to improve suspension performance. When installing your new 47T aluminum sprocket, always pair it with a fresh, high-quality 520 chain. Using a stretched or worn chain on a new aluminum sprocket will cause the teeth to "hook" prematurely. We recommend using new sprocket bolts and applying a small amount of medium-strength thread locker to ensure they stay secure under heavy torque. For riders frequenting technical enduro terrain, the 47T count offers excellent versatility across 250cc and 300cc platforms.

FAQ Questions

Q) Will this fit the newer Beta RR models?
A) Yes, the 1211-822 hub pattern is the standard configuration for Beta RR and RS models, along with several Gas Gas and Sherco applications.

Q) Why choose T651 aluminum over standard T6?
A) T651 receives an extra tempering process that makes the material more stable, meaning the sprocket is less likely to warp or distort under the high heat and tension of racing.
