Sharing some elements with the world of motorcycles, for example gears, the Vespa can be considered the reference of scooters.
Since the Vespa is devoid of crown and pinion and cannot change its center distance, it is difficult to make the necessary modifications to support each increase in performance with the correct transmission ratio.

To solve this problem, Malossi has created the new multi-shift gear for Vespa characterized by a different and more suitable gear transmission ratio, available in two versions, Sport and Racing, which can be used by the Special 50 and even the ET3. 125.

The Malossi company designers have studied two different transmission ratios for the second, third and fourth gear, calculated specifically for engines more prepared for torque, in the Sport version 6716696 (Z10-14-17-20 cal15), or for engines prepared for the track, in the Racing version 6716207 (Z10-15-18-20 cal 15).

The Malossi multi-shift gear is perfectly interchangeable with the original and does not need any modification to its compartment. In addition, thanks to the meticulous research on the correct sizing of the tooth, it can work perfectly in combination with the other gears. The choice of this precise module, in effect, has made it possible to keep the inter-axis unchanged. This highly prestigious technical solution guarantees remarkable reliability and a significant reduction in gearbox noise.
