The ProTaper KTM 85SX-105SX / Gas Gas MC85 / Husqvarna TC85 Rear Orange Sprocket, part number 033404, is engineered for high-performance powersports applications. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket offers exceptional strength and durability. Its precision CNC-machined construction ensures strict tolerances, providing a perfect fit and reliable operation. The bright orange finish not only enhances the bike’s aesthetics but also delivers corrosion resistance and improved wear life. Designed for easy installation, countersinks automatically center the sprocket to the hub, eliminating the need for a hub center guide, which speeds up the setup process and guarantees accurate alignment. The sprocket features an exclusive Angled Mud Groove on both sides of each tooth, which creates a self-cleaning effect during operation. This innovative design sheds mud and debris away from the sprocket, preventing buildup that could cause horsepower loss and uneven sprocket wear. Additionally, the enhanced tooth surface area—up to 40% more than standard designs—improves contact with the chain, resulting in increased sprocket lifespan and reliable power transfer. Suitable for a range of KTM, Gas Gas, and Husqvarna models from 2004 to 2009, this sprocket is an ideal upgrade for riders seeking durability and performance in challenging riding conditions. Made in the USA, the sprocket is suitable for use in competitive and recreational riding, providing enhanced longevity and consistent performance over time.
