Description
Yamaha OEM counter sprocket nut for R6R engines, 06 to current model years. This nut holds the front sprocket to the output shaft, which means it carries the full drive load of the car.
Use the OEM part here. This is not a place for a hardware store substitute – the nut is a specific grade and thread, and a failure means the sprocket walks off the shaft under power.
Option to add an OEM lock washer, which we recommend. Check your model year, because the R6S and R6R nuts differ. In stock in Fresno, CA.
