ProTaper 51-Tooth KTM/Husqvarna 85 SX/TC 85 Rear Sprocket 208551

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 51-tooth Race Spec rear sprocket, manufacturer part number 208551 and vendor part number 208551, is designed for select KTM, Husqvarna and Gas Gas 85cc motocross motorcycles. Its Angled Mud Groove design creates a self-cleaning effect during operation, helping shed mud that can contribute to horsepower loss and sprocket wear. The groove layout also increases tooth surface area by up to 40 percent over competing sprockets, improving chain contact and potentially extending sprocket life.

Precision CNC machining and countersinks that automatically center the sprocket to the hub simplify installation without requiring a hub center guide. The sprocket is made from 7075-T6 heat-treated billet aluminum and features a deep penetrating anodized finish to help protect against corrosion and improve wear resistance. The exclusive mud-groove design is present on both sides of every tooth. Made in the USA.
