ProTaper 033220 Race Spec Rear Sprocket Black 50 Teeth 520 Honda Yamaha

The ProTaper 033220 Race Spec (RS) Rear Sprocket is a 50-tooth, 520-pitch black anodized sprocket engineered for Honda and Yamaha off-road and motocross motorcycles. Crafted from 7075-T6 heat-treated billet aluminum and precision CNC-machined to the strictest tolerances, this sprocket delivers the ideal balance of lightweight performance and long-lasting durability.

At the heart of the Race Spec design is ProTaper's exclusive Angled Mud Groove — machined into both sides of every tooth. This proprietary feature creates a self-cleaning effect during operation, continuously shedding mud and debris that would otherwise cause horsepower loss and accelerated sprocket wear. The unique groove geometry also increases tooth surface area by up to 40% over competing sprockets, resulting in dramatically improved chain contact and extended service life.

Key Features:

• 7075-T6 heat-treated billet aluminum construction
• Precision CNC-machined to the strictest tolerances
• Exclusive angled mud groove on both sides of every tooth for self-cleaning performance
