The importance of the grip has been known since the dawn of time.
Man has always sought to make the hold on tools and weapons secure and effective, without neglecting to personalize the grips, sometimes embellishing them with noble materials. Finally, from today, even your motorcycles can have something special: Malossi takes care of it!
The direct contact is almost never missing, the palm and fingertips grip the handle to transmit the command's impulse, sometimes gently, sometimes violently, depending on the temperament or mood of the moment, and the engine, with a sound that is music to the ears of all pilots who live the passion of driving, responds by developing the requested performance and transporting you into the wind.
Malossi grips have no rivals for riding your motorcycle:
they are safe, anatomical, and indestructible, and also charming, because the care of the image is never secondary for us!

The Malossi range for the Vespa offers products with extremely high technology capable of developing performance increases
so exceptional compared to the standard, that it requires the adaptation of other fundamental components
of the vehicle.

Just compare a Vespa PX 200 E produced in 1978, which originally develops a power of 12.35 HP at 5700 RPM, with a Vespa "tuned" with Malossi Kits, which can develop 27.5 HP at 8000 RPM, or more than double
HP at an extremely higher rotation speed, to understand that it was absolutely essential to design a clutch unit capable of withstanding the stresses due to a performance increase of such proportions!



The POWER UP CLUTCH SYSTEM Malossi clutch units are designed to provide a response and overcome all the problems that inevitably arise when the clutch unit technology is not adequate to the other engine components. A traditional clutch, having to transmit more than double the power to the gears, while simultaneously rotating much faster, can lead to bell failures under the effect of
centrifugal force, slipping and deformations that translate into annoying and unsettling metallic noises, up to the classic clutch slipping caused by

The HTQ Malossi gears for Vespa PX inherit the legacy of the first gear project produced by Malossi between the late 80s and early 90s.
Completely redesigned, this pair of primary gears uses a straight-tooth configuration instead of the standard helical ones.
Malossi has worked hard to ensure the exceptional quietness of the gears, achieved with special machining of the teeth and their contact surfaces, meticulously finished and verified with an involute tester.
The HTQ Malossi gears are made using only materials that exceed the strict standards imposed by our technicians through rigorous tests and trials.
The final machining uses CNC machines,
after which the HTQ Malossi gears undergo a complete thermochemical carburizing treatment at 900°C, giving them the required hardness and strength.
The size and quality of the finished gears are finally verified on Zeiss three-dimensional control machines.

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.
