079580230 - Cush Drive Rubber - fits all 750 - 900cc bevel drive Ducati bikes. How do you know you need one? Easy, put your bike on the center stand and in gear. Now grab your wheel and slowly rotate it one way then the other while watching the sprocket carrier and wheel. If you see movement between the two, your rubber is bad.
