ProTaper Yamaha YZ250 Rear Aluminum Sprocket - 48 Teeth - Black

The ProTaper Yamaha YZ250 Rear Aluminum Sprocket - 48 Teeth - Black is a Race Spec (RS) rear sprocket cut from 7075-T6 heat-treated billet aluminum and finished with a deep-penetrating anodized coating that resists corrosion and wear. ProTaper machines an angled mud groove into both sides of every tooth, which sheds mud during riding and increases tooth surface area by up to 40% compared to competing sprockets, resulting in better chain contact and longer sprocket life. Built in the USA to tight tolerances, the sprocket also features countersinks that automatically center it to the hub at installation without needing a separate hub center guide. It fits the Yamaha YZ250 as the lead application and covers a wide range of Yamaha two-stroke and four-stroke motocross and off-road models, as well as select Honda XR250R years.

A 48-tooth rear sprocket sits on the larger end of the rear gearing range, which lowers overall gearing for quicker acceleration off the line and out of corners at the expense of top-end speed.
