Moose Offroad 1210-BET-48-STL Steel 48T Rear Sprocket — 2013-2025 Beta RR / RS / RR-S

Moose Offroad — High-Carbon C45 Steel, CNC Precision, and Long-Distance Durability

Equip your machine with the ultimate in drivetrain longevity using the Moose Offroad 1210-BET-48-STL Steel Rear Sprocket. Specifically engineered for the Beta RR and RS lineup, this 48-tooth sprocket is designed for riders who prioritize wear resistance and reliability over all else. Whether you are navigating abrasive mud, deep sand, or putting down high-mileage dual-sport miles, this high-carbon steel sprocket outlasts aluminum alternatives by a significant margin, making it the smartest choice for the long haul.

Every Moose Offroad steel sprocket is manufactured from premium-quality C45 high-carbon steel and is 100% CNC precision-machined to ensure incredibly tight tolerances and perfect concentricity. To balance strength with weight management, the sprocket is designed with strategic lightening holes that reduce rotating mass without compromising the structural integrity of the gear. The attractive bright zinc-plated finish not only looks professional but provides a critical layer of corrosion resistance against the elements and chemical cleaners.

• Premium C45 High-Carbon Steel: Delivers maximum wear resistance for extreme off-road and high-mileage conditions.
• CNC Precision Machined: Guarantees a perfect fit and smooth chain tracking to reduce drivetrain friction.
• Lightened Design: Strategic machining removes unnecessary weight while maintaining the superior strength of steel.
• Bright Zinc Plating: Protects against rust and corrosion while providing a clean, factory-style aesthetic.
• Standard 48-Tooth Gearing: The ideal "all-around" tooth count for a perfect balance of low-end torque and top-end speed.

Moto-House MX Pro Tip:

Steel sprockets are the "fit and forget" solution for serious off-road riders. When installing your new Moose Offroad 48T sprocket, always inspect your drive chain and front countershaft sprocket. To maximize the lifespan of your drivetrain, we recommend installing a fresh 520 sealed O-ring or X-ring chain at the same time. During installation, use a set of high-quality sprocket bolts and apply medium-strength thread locker to the threads. A properly maintained steel drivetrain can provide hundreds of hours of reliable service even in the harshest riding environments.

FAQ Questions

Q) Why should I choose steel over aluminum?
A) While aluminum is lighter, steel is significantly more durable. If you ride in muddy conditions or do a lot of dual-sport riding, steel will last 3-4 times longer than a standard aluminum sprocket.

Q) Will this fit the 2025 Beta models?
A) Yes, this sprocket uses the standard Beta 6-bolt pattern and is verified to fit Beta RR and RS models up to 2025.
