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

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, that is, more than double the HP at an extremely higher rotation speed, to understand that it was absolutely necessary to design a clutch group capable of withstanding the stresses due to such a performance increase!

The Malossi POWER UP CLUTCH SYSTEM clutch groups are designed to provide a solution and overcome all the problems that inevitably arise when the clutch group's technology is not adequate to the other engine components. A traditional clutch, having to transmit to the gears more than doubled power, while having to rotate much faster, can lead to failures of the bell under the effect of centrifugal force, to slipping and deformations that result in annoying and not very reassuring metallic noises, up to the classic clutch slippage caused by the insufficient friction developed by the

The V-One is designed for those who want a casing perfectly replaceable with the original, provided with all the components necessary for assembly and allowing maximum interchangeability with components available on the market, it requires no 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 provided). 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 intake has been reviewed and implemented thanks to our modern
CAD systems that have profiled an optimized intake duct in the casing.

MHR Version: The MHR version differs from the SPORT one not only in the exhaust port, but also in the decidedly racing transfer diagrams.

Malossi power exhaust has been redesigned, increasing the power compared to previous models by about 5%, thanks to an in-depth study that involved the internal surfaces of the sheet metal with which the expansion is made.

Manage multiple maps simultaneously without the need for handheld devices, with a simple click. Allows you to shift the selected map by moving the OFFSET (+ or - 2°).

Malossi ignitions concentrate the maximum technology applied to competitions. The new internal rotor ignitions are born from the need to overcome the technical limitations of the original flywheel-ignition groups, which beyond 10,000 rpm do not guarantee consistent performance, causing significant and sometimes insurmountable tuning problems.

We have made the control unit even more immune to disturbances, developing a microprocessor based on uP STM8 - 8 Bit with superior computing capacity @ 20 MIPS to ensure much higher spark precision compared to the previous version!

The MHR Team II range is equipped with a non-remappable variable advance control unit with 3 trimmers:


the first (MAPS) to determine the selection of the advance map
the second (OFFSET) allows you to shift the selected map + or – 2°
the third (LIM) particularly indicated for 4-stroke engines, allows you to vary the intervention of 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 gears.
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.
HTQ Malossi gears are made using exclusively materials
that exceed the strict standards imposed by our technicians with 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
resistance.
The size and quality of the finished gears are finally verified on Zeiss three-dimensional control machines.
Paired in pairs to ensure the correct operating clearance, HTQ Malossi gears are the most precious gift a true romantic enthusiast can give to their Vespa.

HTRoll
HIGH RESISTANCE CALIBRATED ROLLERS
for original variators and Multivar

HTRoll are made of CPT with a specific formula and
have the corresponding weight marked on one side.
HTRoll represent a technical replacement for the original and are
a complete series of calibration elements capable of varying the transmission
ratio of your scooter, perfectly adjusting its speed
and acceleration.

Operation
Due to rotation, the weight of the rollers transforms into centrifugal
force: the greater the weight of the roller, the greater the centrifugal force and
the shorter the shift time, and vice versa.

Variator calibration
To optimize engine performance, use rollers that during
use keep the engine in the maximum power rotation range.
By reducing the weight of the rollers, the engine increases the number of
operating revolutions, conversely, by increasing the weight of the rollers, the
number of revolutions decreases.

The X Special Belt V-belts are the best choice to ensure performance and reliability for your scooter.


They are produced with compounds designed to ensure optimal resistance and traction, and their shapes have been fine-tuned to perfectly adhere to the surfaces of the automatic transmission components.
The X Special Belt is not only perfectly interchangeable with the original belt, but it also offers all the advantages of Malossi product quality.
