The ProTaper Yamaha Rear Black Sprocket (Part Number 033214) offers advanced performance features designed for motocross and off-road enthusiasts. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket provides exceptional strength and durability for demanding riding conditions. Its precision CNC-machined construction ensures strict tolerances, resulting in a perfect fit and reliable operation. The deep penetrating anodized finish not only enhances corrosion resistance but also improves wear resistance, extending the sprocket’s lifespan. The innovative Angled Mud Groove design on both sides of each tooth creates a self-cleaning effect during operation, shedding mud and debris that could otherwise cause horsepower loss and sprocket wear. This feature helps maintain optimal power transfer and prolongs sprocket life, making it an ideal upgrade for competitive riders. The sprocket's design includes countersinks that automatically center it to the hub during installation, eliminating the need for a hub center guide and simplifying setup. Engineered to fit a variety of Yamaha models including the WR and YZ series from 2009 to 2011, this sprocket is a perfect choice for riders seeking improved traction, durability, and ease of maintenance. ProTaper's commitment to quality and innovation ensures this sprocket meets the highest standards, providing reliable performance on the toughest trails and tracks.
