ProTaper 49T Race Spec Rear Sprocket, Model 033510

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 Race Spec rear sprocket is designed for select 2025 and 2026 65cc powersports applications, including the KTM 65 SX, Gas Gas MC 65 and Husqvarna TC65. This black rear sprocket features ProTaper’s exclusive Angled Mud Groove design, which creates a self-cleaning effect during operation to help 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 promoting extended sprocket life.

Precision CNC machining ensures the sprocket is manufactured to strict tolerances. Countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide. A deep penetrating anodized finish helps protect against corrosion and improves wear resistance, while mud grooves on both sides of every tooth support consistent performance in challenging riding conditions.

Constructed from heat-treated 7075-T6 billet aluminum and made in the USA, this 49-tooth ProTaper rear sprocket is identified by manufacturer part number 033510 and vendor part number 033510. Fitment includes the 2025 and 2026 Gas Gas MC 65, 2025 and 2026 Husqvarna TC65, and 2025 and 2026 KTM 65 SX.
