The ProTaper KTM 85SX-105SX Rear Black Sprocket, part number 033278, is engineered for high-performance motocross applications. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket offers exceptional strength and durability for demanding off-road racing. Its precision CNC-machined construction ensures strict tolerance adherence, providing a reliable fit for KTM 85SX, KTM 105SX, Gas Gas MC85, and Husqvarna TC85 models. The deep penetrating anodized finish not only enhances corrosion resistance but also extends wear life, making it a durable choice for intense riding conditions. The sprocket features an innovative Angled Mud Groove design on both sides of every tooth, which creates a self-cleaning effect during operation, shedding mud and debris that could otherwise cause horsepower loss and sprocket wear. This design maintains optimal contact with the chain, improving power transfer and extending sprocket lifespan. The countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide and simplifying setup. Suitable for various KTM, Gas Gas, and Husqvarna models from 2004 to 2009, this sprocket combines advanced features with a sleek black finish for a professional appearance. Whether racing or riding in muddy conditions, the ProTaper rear sprocket delivers reliable performance and increased durability, making it an essential upgrade for serious motocross enthusiasts.
