Malossi Set of 19x15,5mm 5gr - 6 pieces Universal Variator rollersRef : MAL00161A / 1007767

MALOSSI roller weights 19x15.5 mm in a pack of 6, manufacturer reference 66 9420.C0. Made from CPT with a specific formula, these weights are a reliable technical replacement for urban scooter variators. Ideal for riders who want to adjust the engine response without deeply modifying the transmission.

Operating Principle

The weights play a crucial role in the variator: under the effect of rotation, their mass generates a centrifugal force that pushes the pulleys closer together, altering the gear ratio. The heavier the weight, the earlier the engagement occurs (at low RPM); the lighter the weight, the higher the engine must rev before reaching the high ratio. This set of 5 g weights allows for adjustment of the scooter's behavior according to usage.

Usage and Tips

For urban use (traffic, frequent starts), choosing an appropriate weight helps improve acceleration and smoothness at takeoff. These weights are designed to be combined with a compatible variator synchronizer and clutch for harmonious tuning.
