The HTRolls represent a technical replacement for the original and are a complete series of calibration elements capable of varying the transmission ratio of your scooter, perfectly regulating its speed and acceleration. As a result of the rotation, the weight of the rollers is transformed into centrifugal force: the greater the weight of the roller, the greater the centrifugal force and the shorter the shifting time and vice versa.
