The new Polini driven pulley has been designed to increase the performance of your scooter's engine by giving it the ability to deliver all its power with a longer belt travel, which is why it is necessary to combine a longer belt. Two grooves with inclinations of 36 and 38 degrees characterize this mobile half-pulley so as to optimize the transmission of power to the wheel while maintaining the engine speed at maximum torque. The different inclination of the two grooves varies the axial force with which the half-pulley acts on the belt; for this reason it is necessary to use Polini contrast springs with the Speed Drive.
