complete drive unit over range
Code: 6119262Model: piaggio boss 50 2t
Description
The upgrading of the Big Deps engine and the Malossi crankcase, has led to a deficit in the transmission of this vehicle, to overcome which the great experience of Malossi engineers has designed a complete Over Range, suitable to support constantly increasing performance.
This latest system hinges on the new Fixed Pulley of the torque driver that has a larger diameter and the very latest specifications. The larger diameter of this pulley allows one to have a greater velocity-ratio range compared to the original pulley that has a notably smaller external diameter.
Malossi engineers have also taken particular care in realising this pulley right down to the smallest detail, using special materials and a particular type of thermochemical treatment that ensures exceptional surface hardness and therefore excellent wear and abrasion resistance. This new fixed pulley has been designed to off er perfect running if coupled to the Malossi Torque Driver that has the same diameter as the fixed pulley itself.
To complete the renewal of the transmission system and take full advantage of its exceptional specifications, the MHR Multivar variable-speed drive has also been upgraded by fitting it with new tracks for the rollers, new variator adjuster spring and a new hub a new hub which is longer than the previous one and therefore able to combine with a more powerful belt and optimise the ratios. This new variable-speed drive represents the evolution of the previous generations, the result of many years of experience on the race circuit and the currently available CADCAM technology that allows top-level specifications to be obtained.
To fully exploit the range of the new torque driver unit and the power ratings currently off ered by competition machines, a new notched Special Belt has been introduced with larger section and revised length to ensure maximum performance under all running conditions (sold separately).
Attention: after fitting the Malossi Over Range it will no longer be possible to start the vehicle by
pushing, it will be necessary to use special starting tools (not included in the kit).
THE KIT CONSISTS OF :
- Multivar MHR variator
- New roller tracks
- New contrast spring
- Longer hub
This is the first time that Multivar MHR has been adopted on the moped scene!
Malossi has completely redesigned this variator:
- Torque Driver
- New pulley set, consisting of fixed and movable pulley with Ø increased from 100 to 110 mm
- One-piece welded fixed and moving pulley with especially surfacetreated bushing
This is the great novelty of this kit: the ability to house a true torque driver with double sliding rails to customise the gear curve as desired!
- Fly Clutch
Ø 107 mm clutch, redesigned with
new masses to adapt to the opposite
direction of rotation.
The Malossi spring coupling allows
operation at a predefined optimum RPM
attack point.
Optional: 2 sets of springs are available
to customise your vehicle.
- 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
We went as far as modifying the primary
gear shaft to accommodate a pulley
and clutch/bell assembly derived from
the scooter world.
Having become the connecting
element between the newly designed
components, this shaft has been
reinforced with an increase in the shaft
Ø to 13.5 and is supplied with a nut, oil
seal and roller shell for mounting.
- Special Belt (sold separately) Belt with section increased by 23% (from 13 to 16 mm)
