From Malossi themselves- 

 

The transmission is one of the key components in a scooter. The kit Malossi MHR Aluminum Over Range is designed to improve efficiency and engine power, ensuring longevity and tuning flexibility.

The centerpiece of the new kit Malossi variator transmission remains the Multivar, in constant evolution, which is accompanied by two sets of rollers to adjust the operation of the transmission according to your needs. With the wide range of variator rollers available in our catalogue, the set-ups are virtually endless.

The variator's sliding roller ramps have been redesigned to maximize the transmission's performance. Malossi, always searching for perfection, has also revised the hub, in addition to chrome plating and grinding, it is subjected to a vibratory finishing process, one of the most recent and avant-garde techniques, resulting in a mirror like finish.

For the first time, the variator Malossi MHR Aluminum Multivar is supplied with the fixed half pulley - Ventilvar.

On the other side of the crankcase there is the new Torque Driver - Malossi Aluminum Rear Pulley System MHR Aluminum, now in aluminum 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.

The Torque Driver is made of aluminum, a material with exceptional heat dissipation, and was subjected to a micro perforation process to increase transmission belt grip and to keep it clean and efficient, expelling from the holes any heat created contaminants.

The drive belt is a Malossi X K Belt, based on the technology developed for the maxi-scooter belts, has an extremely small cross section and intended for two-stroke scooter racing, guaranteeing grip and consistent performance.
