Malossi Variator 19x15,5mm 7,2gr - of 6 Universal Variator rollersRef : MAL00293A / 1007774

Set of 6 MALOSSI rollers 19 x 15.5 mm, 7.2 g each (manufacturer reference 66 9420.M0). Designed for scooter variators, these rollers are made from CPT according to the MALOSSI formula and serve as a technical replacement part suitable for adjusting the behavior of the final transmission.

Operation

The rollers act as moving masses in the variator: as they rotate, their weight generates a centrifugal force that pushes the weights and modifies the shift point of the gears. The choice of weight directly affects the engine speed under load — lighter rollers promote a higher RPM, while heavier rollers lower the RPM. Adjusting the weight allows you to fine-tune acceleration, responsiveness, and power range according to your riding style or the characteristics of the engine.
