ProTaper 48T Race Spec Rear Sprocket, Model 033509

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, model 033509, is a 48-tooth sprocket designed for select 2025 and newer KTM 65 SX, Gas Gas MC 65, and Husqvarna TC65 applications. 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 grooves are positioned on both sides of every tooth to support improved chain contact in demanding riding conditions.

Precision CNC machining and a unique tooth layout provide up to 40% more tooth surface area than competing sprockets, according to the manufacturer. Countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide. The deep penetrating anodized finish helps protect against corrosion and improves wear resistance.
