Variator rollers GY-6, DIO 5.5 g — variator rollers for 4-stroke scooters. The rollers move in the variator drive plate and change the gear ratio. The weight, 5.5 g or 6.5 g, is given in the product name.
Replacement is needed when you hear knocking, the rollers are worn, or the scooter accelerates sluggishly or does not reach top speed. It is best to keep the old part until the new one is installed, so you can check the dimensions and the position of the holes.
