ProTaper 033222 Race Spec RS Aluminum Rear Sprocket Black 51T Honda/Yamaha

The ProTaper 033222 Race Spec (RS) Aluminum Rear Sprocket delivers professional-grade performance for Honda and Yamaha dirt bikes and off-road motorcycles. Built from 7075-T6 heat-treated billet aluminum and precision CNC-machined to the strictest tolerances, this 51-tooth rear sprocket is engineered for riders who demand reliability and longevity in demanding conditions.

Key Features:

• Exclusive Angled Mud Groove Design – ProTaper's revolutionary mud groove creates a self-cleaning effect during operation, expelling mud and debris that would otherwise cause power loss and accelerated sprocket wear
• 7075-T6 Heat-Treated Billet Aluminum Construction – Premium aerospace-grade alloy provides an exceptional strength-to-weight ratio for off-road use
• Up to 40% More Tooth Surface Area – The precision CNC-machined mud groove layout increases tooth surface area significantly over competing sprockets, improving chain contact and extending sprocket life
• Self-Centering Countersink Design – Integrated countersinks automatically center the sprocket to the hub during installation, eliminating the need for a separate hub center guide
• Mud Groove on Both Sides of Every Tooth – Full dual-sided groove coverage ensures consistent self-cleaning performance in all conditions
• 51 Teeth – Black Anodized Finish – Durable anodized black finish resists corrosion and wear

The ProTaper Race Spec RS rear sprocket is a direct upgrade over stock units, offering superior chain engagement, reduced drivetrain wear, and a longer service life. Designed for motocross, trail riding, and enduro applications.
