The ProTaper Yamaha Rear Black Sprocket with 46 teeth is engineered for high-performance off-road riding and racing applications. Crafted from 7075-T6 heat-treated billet aluminum, this sprocket combines durability with lightweight strength to withstand the rigors of aggressive riding. Its CNC-machined construction ensures precise fitment and consistent performance, while the deep penetrating anodized finish offers excellent corrosion resistance and enhanced wear life. Designed specifically for Yamaha models from 2009 to 2011, including WR and YZ series, this sprocket guarantees optimal compatibility and performance. The innovative Angled Mud Groove on each side of the teeth provides a self-cleaning effect during operation, shedding mud and debris that can cause horsepower loss and sprocket wear, thereby maintaining maximum efficiency in muddy or challenging terrains. The design increases contact surface area with the chain by up to 40%, resulting in improved chain engagement, reduced sprocket wear, and extended service life. The countersinks automatically center the sprocket to the hub during installation, eliminating the need for a hub center guide and simplifying setup. The sprocket’s balanced design ensures minimal vibration and smooth power transfer. Manufactured in the USA, the ProTaper Yamaha Rear Sprocket offers a reliable upgrade for riders seeking increased durability, better chain engagement, and superior performance on the trail or track.
