Talon GYTR Rear Sprockets
2010 Yamaha YFZ450X
Made from 7075-T6 billet aluminum CNC-machined for maximum fit accuracy. Features a radial mud groove etched just inside the sprocket teeth to shed mud and grit which saves weight and increases chain life. Used by the Star Valli Yamaha Team, AmPro Yamaha Off-Road Team, and Yamaha Amateur Support Riders.
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.
