Race Spec (RS) Rear Sprockets feature our revolutionary Angled Mud Groove. This exclusive design creates a self-cleaning effect during operation, shedding away mud that would otherwise lead to horsepower loss and sprocket wear. With their precise CNC machining and unique layout, these grooves also allow an increase in tooth surface area of up to 40% over competing sprockets. As a result, contact with the chain is significantly improved, leading to a marked increase in sprocket life over other brands. That's the ProTaper difference.
- Countersinks automatically center sprocket to hub during installation, no hub center guide needed
- Deep penetrating anodized finish protects from corrosion and improves wear resistance
- Exclusive mud-groove design on both sides of every tooth
- Precision CNC-machined to the strictest tolerances
- 7075-T6 heat-treated billet aluminum
- Made in USA
The ProTaper Honda/Yamaha Rear Blue Sprocket, part number 033225, is engineered for high-performance motocross and off-road riding. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket offers exceptional strength and durability for demanding riding conditions. Its precise CNC machining ensures strict tolerances, providing a reliable fit and optimal performance. The sprocket's deep penetrating anodized finish offers superior corrosion resistance and enhances wear longevity, making it a dependable choice for riders seeking durability and consistent performance.
The unique feature of the Race Spec (RS) rear sprocket is the revolutionary Angled Mud Groove. This exclusive design creates a self-cleaning effect during operation, shedding mud and debris that could otherwise cause horsepower loss and sprocket wear. The mud grooves are incorporated on both sides of each tooth, which significantly improves chain contact and distributes wear evenly. As a result, this sprocket provides up to 40% more tooth surface area compared to competing models, leading to increased sprocket life and smoother power transfer.
Installation is straightforward thanks to the countersunk design, which automatically centers the sprocket on the hub, eliminating the need for a hub center guide. The sprocket is compatible with a range of Honda and Yamaha models, including popular bikes like the 1988-1989 Honda XR250R, as well as Yamaha models from 2009 through 2011 such as the WR250F and YZ450F. Built in the USA, this sprocket combines quality manufacturing with innovative features suitable for riders who demand top-tier performance and longevity in their drivetrain components.
