The power developed by an engine, whether standard or modified, will be pointless if it is not transmitted to the wheels in the most efficient and effective way, without unnecessary friction and waste of mechanical energy.

Malossi, a leader in the production of high-performance components for the scooter world, has focused all its know-how by completely redesigning the primary transmission for the classic Vespa "small frame" to ensure that the maximum power is transformed into road performance.

The new Malossi primary transmission for the Vespa is a true concentration of engineering. From the highest quality materials to the attention to detail and the quality of mechanical processes, everything is brought to a very high level. From the bronze bushing to the clutch basket and gears, everything is worked separately to ensure that each individual component is produced according to the highest quality standard.

The core of the innovations introduced in this transmission is the new clutch bell, made from special solid steel and characterized by six slots for the clutch discs, all six "active" and designed to lock the discs. In this way, all mechanical play is minimized, as are vibrations and the consequent wear of the basket itself and the guide teeth of the discs.

When technology makes a difference.
Multivar: the sports transmission with blazing acceleration that leaves no room!
A jewel to be embedded in your scooter. It's a shame it can't be shown off, it's so perfect!
Designed by highly experienced engineers, entirely produced in Malossi factories by high-precision robotic systems.

With such a technically sophisticated variator, don't be surprised if your scooter gains a burst, a smoothness in shifting, greater mechanical "calmness" at high speeds, and a consistency of performance unknown to the base version.

The V-One is designed for those who want a perfectly
replaceable casing with the original, provided with all the components
necessary for assembly and allowing maximum interchangeability with the
components available on the market, it does not require any aesthetic modification
of the vehicle and fits all original Piaggio parts.
The crankcase seats are designed to accept the original crankshaft bearings and seals (not supplied). V-One can be mounted with the
original Dell’Orto Si 24-24 carburetor. It is possible to use
the original crankshaft or our rotary valve crankshaft with a 57mm stroke art. 5316082. Whatever the choice,
the fuel supply has been revised and enhanced thanks to our
modern CAD systems that have profiled an optimized intake duct in the casing. Entirely made in ITALY
