Upgrade your dirt bike with the ProTaper KTM 85SX-105SX Rear Orange Sprocket, designed for optimal performance and durability. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket offers exceptional strength while maintaining a lightweight profile for improved handling. The precision CNC-machined construction ensures strict tolerances, providing a perfect fit and smooth operation. The vibrant orange finish not only enhances the bike’s aesthetic but also adds a layer of corrosion resistance, extending the sprocket's lifespan.
The Race Spec (RS) design features our revolutionary Angled Mud Groove, a unique feature that creates a self-cleaning effect during operation. This innovative groove sheds mud and debris that could otherwise cause horsepower loss and sprocket wear, ensuring consistent performance even in muddy or challenging conditions. The design also increases the contact area with the chain by up to 40%, significantly improving chain engagement and reducing sprocket wear. This results in increased sprocket longevity and reliable power transfer.
Features include automatic countersinking, which centers the sprocket to the hub during installation without additional guides, making setup quicker and easier. The deep penetrating anodized finish provides excellent corrosion resistance and enhances wear resistance, maintaining the sprocket's appearance and performance over time. The sprocket's aggressive tooth layout with mud grooves on both sides contributes to self-cleaning during rides, reducing maintenance and improving overall efficiency. Made in the USA, this sprocket is compatible with a range of KTM, Gas Gas, and Husqvarna models from 2004 to 2009, making it a versatile upgrade for riders seeking durability and high performance.
