J.Costa Roller mass JC16034015016M GR.15X16

It is important to choose rollers that are appropriate for your motorcycle and riding style. Rollers that are too light can overheat the variator and cause damage, while rollers that are too heavy can overload the motor and cause it to overheat. It's also important to check the condition of the rollers regularly and replace them if necessary, as wear can affect their weight and shape and interfere with the variator's operation.
