ProTaper 40-Tooth KTM 50 SX Rear Sprocket 033184

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
• 7075-T6 heat-treated billet aluminum PTSE Hard Coated
• Precision CNC-machined to the strictest tolerances
• Made in USA

Its exclusive Angled Mud Groove design creates a self-cleaning effect during operation, helping shed mud that can contribute to horsepower loss and sprocket wear. CNC-machined grooves increase tooth surface area by up to 40 percent over competing sprockets, improving chain contact and supporting increased sprocket life.

The sprocket is manufactured from 7075-T6 heat-treated billet aluminum and features a PTSE hard coating. A deep-penetrating anodized finish helps protect against corrosion and improves wear resistance. Countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide. Precision CNC machining and manufacture in the USA complete the ProTaper Race Spec design.
