YAMAHA OEM GYTR Aluminum Rear Sprockets Blue DBY-ACC56-33-06/GYT-0SS56-30-19
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.
This accessory is restricted to closed-course competition use.
