Thus, the Over Range is renewed as well: new variator! This new system is based on Multivar MHR Next , which – matched with the other parts - allows to achieve really unique performances! The torque driver (movable pulley) has a larger diameter compared to the original one and the very latest specifications, allowing to have a greater velocity-ratio range compared to the original pulley. Malossi engineers have also taken particular care in realising this pulley right down to the smallest detail, using special materials and a particular type of thermochemical treatment that ensures exceptional…

Half-pulley made of aluminium alloy with silicon content, machined on very high precision CNC machines and diamond-finished, with recalculated profiling of the roller sliding guides.

This consists of a 15° pulley with a diameter of 102 mm, which is TIG welded to a specially designed hub with a mould-pressed EKU bushing. EKU is a dry self-lubricating material that ensures excellent sliding properties and minimal wear. Adaptable even to the original Piaggio system.

Half-pulley assembly for 50cc 2-stroke scooters Not every component is born to boost performance; some are simply essential to keep things running . Our half-pulley assembly for 50cc 2-stroke scooters is designed for those who need to replace original parts that are subject to wear and often hard to find. It is a technical replacement part equivalent to the original one , intended for anyone looking to get their 50cc 2-stroke scooter back on the road or replace an aging stock component. Technical specifications The assembly consists of: a fixed steel half-pulley with a starter ring gear and a…

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…

Torque Driver Malossi Aluminium Rear Pulley System MHR Aluminum, now in aluminium for lightness and strength increase. The pulley is riveted to the hubs for maximum strength and to reduce the tolerance between the hub and the bushing. The surface roughness is just Ra 0.4.

"OVER RANGE" Malossi transmission system This new transmission system takes full advantage of the Malossi components already on sale last year, by adding several new parts that make the entire system particularly suited to the enormous power available. This latest system hinges on the new Fixed Pulley of the torque driver that has a larger diameter and the very latest specifications. The larger diameter of this pulley allows one to have a greater velocity-ratio range compared to the original pulley that has a notably smaller external diameter. Malossi engineers have also taken particular care…

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…
