Variator Malossi MHR Team 2 Aluminium Piaggio ZIP / NRG

Tuning CVT from the Malossi's racing R&D: Variator Malossi MHR Team 2 Aluminium Piaggio ZIP / NRG for Piaggio and Aprilia (with Piaggio engine), suitable for Malossi C-One, Polini PRE and TPR crankcases.

Malossi's engineers have made every effort to eliminate the problems typically found in tuning CVTs: seizing of the variator sleeve, belt slip, inefficient power transmission to the wheel, deformation of relevant components, non-guaranteed smooth and stable transmission. 

This is a self-lubricating CVT. The components sitting on the sleeve, or bush, must be able to slide smoothly and frictionless at all times, any deformation would be a major disadvantage at this point. This is why Malossi uses hardened steel bushes, the bushes are ground inside and outside so the surfaces offer even less resistance. The grease inside the bushing is evenly distributed via 2 oil seals. All this results in minimum friction and therefore efficient power transmission to the rear wheel and maximum power development.

The 22mm variator sleeve also has small perforations through which the grease can pass from the inside to the outside to ensure optimal lubrication. This optimal lubricating film also allows for the tolerances in designing the other components to be further reduced, thus improving the precision and overall design.

The movable pulley has a diameter of 99.5 mm and is cast from a special aluminium alloy. The contact surface between pulley and V-belt was machined with a diamond tool to ensure a stable friction coefficient so that the belt does not slip, but also does not wear too quickly.

The kit includes:

• variator complete with 22mm sleeve
• pulley / fan wheel
• 2x sets of weights 19x15,5mm (3,8g and 4,3g)
• torque spring, purple (art.-no. M298324.V)
• 1 tube of grease MHR
