Malossi Over Range MHR ALUMINUM Full Transmission Yamaha Minarelli long

The Malossi MHR Aluminum Over Range kit is designed to improve engine efficiency and power, while also ensuring durability and flexibility in adjustments.

The heart of the new transmission kit is the constantly evolving Malossi MULTIVAR variator, which is accompanied by two sets of rollers to adjust the transmission's operation according to individual needs.

Thanks to the wide range of variator rollers available in the catalog, customization options are practically infinite.

Inside the variator, the roller sliding ramps have been redesigned to maximize transmission balance.

But Malossi didn't stop there. They also revised the hub, which is not only chromed and rectified, but also subjected to a vibrofinishing treatment, one of the most recent and advanced mirror finishing techniques.

For the first time, along with the Malossi MULTIVAR MHR Aluminum variator, the fixed VENTILVAR pulley is also provided.

On the other side of the casing, you'll find the new Malossi Rear Pulley System MHR Aluminum torque driver, now made of aluminum to increase lightness and strength.

The pulley is firmly attached to the hubs to ensure maximum grip, and the tolerance between the hub and the bushing has been reduced to a roughness degree of just Ra.04.

The Torque Driver torque converter is made of aluminum, a material with excellent heat dissipation properties, and has undergone microdrilling treatment to increase the grip of the transmission belt and keep it clean and efficient by expelling heat-fused particles through the holes.

The X K Belt Malossi transmission belt, based on the technology used for belts designed for maxi-scooters, features an extremely reduced section and is intended for competition two-stroke scooters, ensuring grip and consistent performance.
