Malossi Set of 25x14,9mm 16gr - 8 pieces Variator rollersRef : MAL00200A / 1007903

Set of 8 MALOSSI rollers 25 x 14.9 mm, weighing 16 g per roller — a reference for the maintenance and tuning of various transmissions for urban scooters. Made from CPT according to a specific MALOSSI formula, these rollers serve as a technical replacement part for the variator and directly influence the behavior of the secondary drive.

Operation

The principle is simple and mechanical: under the effect of rotation, the weight of the rollers generates a centrifugal force that pushes the rollers outward from the variator. The choice of diameter, width, and weight affects the engagement moment and the RPM range at which the variator oscillates.

Variator Adjustment

By changing the weight of the rollers, you can adapt the acceleration curve and the responsiveness of the scooter. Lighter rollers favor a higher RPM, while heavier rollers delay the RPM rise — a useful adjustment to optimize use in urban environments according to your riding style.
