The ProTaper Yamaha YZ85 Rear Aluminum Sprocket - 50 Teeth - Black is a Race Spec (RS) rear sprocket cut from 7075-T6 heat-treated billet aluminum and finished with a deep anodized coating that resists corrosion and wear. ProTaper machines an angled mud groove into both sides of every tooth, which helps shed mud during riding and increases tooth surface area by up to 40% compared to competing sprockets, meaning more chain contact and longer sprocket life. Built in the USA, it fits the Yamaha YZ85 as well as several Suzuki RM80 and RM85 models, and its countersunk mounting holes self-center the sprocket to the hub during installation without a separate hub center guide.
A 50-tooth rear sprocket sits on the larger end of the range, which lowers your overall gearing for stronger acceleration off the line and out of corners at the cost of some top-end speed.
