TORQUE DRIVER The mobile driven split pulley comes from our racing department's many years of experience, and is manufactured with the best possible special nitrided steels in order to ensure a long life. This component called Torque Driver for its specific function of determining the exact shifting moment, was calculated to give the vehicle the maximum possible acceleration in connection with the specific power of any single engine. The spiral's peculiar shape was studied to fix the RPMs on the point of maximum power. It was expressly created to complete the development of boosted motors…

VENTILVAR 2000 It’s a fixed half-pulley with a diamond finish of the belt-side pulley surface and a redesigned working angle to further increase the gearing range. This component completes the Multivar and renders it unparalleled. Specially designed for the line of variable-speed drives for scooters, it further improves the performance of the drive belt. It is not just a simple accessory, but a very important part for guaranteeing the long life of all the transmission components. The temperatures produced inside the crankcases where variators work with V-belts are prohibitive at critical…
