Description
The ProTaper Race Spec (RS) Rear Sprocket features a revolutionary Angled Mud Groove, delivering a self-cleaning effect that sheds mud during operation to prevent horsepower loss and premature sprocket wear. Precision CNC machining and a unique groove layout increase tooth surface area by up to 40%, vastly improving chain contact and extending sprocket life. Designed specifically for 2025 KTM 65 SX and Husqvarna TC 65 models with 46 teeth.
