The ProTaper KTM 85SX-105SX Rear Black Sprocket with 47 teeth is engineered to deliver superior performance and longevity for your powersports vehicle. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket offers exceptional strength and corrosion resistance, ensuring reliable operation in demanding conditions. Its deep penetrating anodized finish further enhances wear resistance, making it a durable choice for off-road enthusiasts. The sprocket features our revolutionary Angled Mud Groove design on each side of every tooth, creating a self-cleaning effect that sheds mud and debris during operation, thus maintaining optimal horsepower transfer and reducing sprocket wear. This innovative feature helps keep the sprocket clean, improving chain contact and extending service life. The sprocket's CNC machining ensures precise fitment and consistent performance, while the unique layout increases the tooth surface area by up to 40% compared to standard designs. This results in enhanced engagement with the chain, smoother power transfer, and increased sprocket lifespan. Designed for easy installation, the countersinks automatically center the sprocket on the hub, eliminating the need for a hub center guide and simplifying setup. Made in the USA, this sprocket is compatible with a range of KTM, Gas Gas, and Husqvarna models from 2004 to 2009, including the KTM 85 SX, KTM 105 SX, KTM 105 XC, KTM 85 XC, and Husqvarna TC85. Built for riders who demand durability, performance, and innovation, the ProTaper rear sprocket is the ideal upgrade for aggressive riding and competitive racing.
