Complete transmission group for Piaggio SI 50 2T

A complete Over Range, suitable to support constantly increasing performances

This new system is based on the new fixed pulley of the Fixed Pulley torque corrector which has a larger diameter and absolutely cutting-edge technological features. To completely renew the transmission system and take full advantage of its exceptional technical characteristics, the Multivar MHR variator has also been updated, equipping it with new tracks for the rollers, a new contrast spring and a new hub longer than the previous one and for this reason in able to combine with a more powerful belt and optimize ratios.

Variator Multivar MHR

Variator Multivar MHR

It is the first time that Multivar MHR is adopted in the moped landscape!
Malossi has completely redesigned this variator:

  • New roller sliding tracks
  • New contrast spring
  • Longer hub

To completely renew the transmission system and take full advantage of its exceptional technical characteristics, the Multivar MHR variator has also been updated, equipping it with new tracks for the rollers, a new contrast spring and a new hub longer than the previous one and for this reason in able to combine with a more powerful belt and optimize ratios. This new variator is the evolution of previous generations: born from the many years of experience acquired on the racing circuits and from the Cad-Cam technology available today, it allows to obtain technical results at the highest levels.

Special Belt

Special Belt

        To take full advantage of the range of the new torque corrector unit and the powers developed today by racing vehicles, a new Malossi Special Belt notched belt has been designed with an increased section and updated length that ensures maximum performance in all conditions of use.

 

        Belt with oversized section, increased by 23% (from 13 to 16 mm)

 

Torque Driver

Torque Driver

Here is the great news of this kit: being able to house a real torque corrector with double sliding tracks to customize the shift curve as you like!

  • New pulley unit, consisting of fixed and mobile pulley with increased Ø from 100 to 110 mm
  • Fixed and mobile pulley welded in one piece, with bush specially treated on the surface

Malossi technicians have taken care of the realization of this pulley down to the smallest details using special materials and a particular type of thermochemical treatment, which gives it a very high resistance to wear and an equally high mechanical resistance. The new fixed pulley has been designed to ensure perfect operation when coupled to the Malossi torque corrector (Torque Driver), which has the same diameter as it.

Fly Clutch

Fly Clutch

Clutch Ø 107 mm, redesigned with new masses to adapt to the reverse direction of rotation compared to that present in the scooter panorama.
The Malossi spring coupling allows operation at a predefined optimal RPM attachment point.
Available as optional 2 sets of springs to customize your vehicle.

Wing Clutch Bell

Wing Clutch Bell

Reinforced clutch bell with a finned cooling ring, perfectly matched to the newly developed high-performance Fly Clutch. This is the only component common to the scooter.

Primary gear shaft

Primary gear shaft

We went as far as modifying the primary gear shaft to house a pulley and clutch / bell unit that comes from the scooter world.
Having become the connecting element between the newly designed components, this shaft has been reinforced with an increase in the Ø of the shank to 13.5 and to be prepared for an external support it is supplied with nut, oil seal and roller shell useful for assembly .
