Malossi MHR Over Range complete transmission for Yamaha Minarelli long engines

The complete Malossi OVER RANGE transmission group for Yamaha and Minarelli engines is an innovative system that offers numerous advantages. Its main feature is the new Fixed Pulley torque corrector fixed pulley, which has a larger diameter than the original pulley. Thanks to this, the transmission ratio can have a much wider range, guaranteeing superior performance.

The fixed pulley is made of special materials and undergoes a special thermochemical treatment, which gives it high wear resistance and great mechanical strength. It is designed to function optimally when coupled with the Malossi torque driver, which has the same diameter.

To fully exploit the available power on competition vehicles, a new Malossi toothed belt in Kevlar® (K) has been introduced, with an increased section and updated length. This belt ensures maximum performance in all operating conditions.

The MULTIVAR variator has also been updated, with new tracks for the rollers and a new hub. This new variator is the result of experience gained on race circuits and Cad-Cam technology, guaranteeing extremely high-level technical results.

To complete the OVER RANGE system, it is possible to add the patented adjustable Delta Clutch and the reinforced Malossi Wing Clutch Bell clutch bell, which are not included in the kit.
