GYTR Rear Sprockets

SKU #GYT-75339-47-BL
The Rear Sprockets are made from 7075-T6 billet aluminum CNC-machined for maximum fit accuracy. The rear sprockets features a radial mud groove etched just inside the sprocket teeth to shed mud and grit which saves weight and increases chain life. Sprocket sizes other than stock are for closed-course competition only on 2006 and later off-road models and all street legal models. Changing the final drive ratio affects exhaust emissions and also affects speedometer readings. YZ models are for closed-course competition use regardless of modification.
