MALOSSI Roller Weights 20x17mm 15g — 6 pieces

Designed by MALOSSI for urban environments, this set of 6 variator rollers is a technical replacement suitable for scooters requiring Ø20 x 17 mm rollers. Made from CPT with a specific formula, these weights replace the original element and directly influence the behavior of the automatic transmission.

Operation

During rotation, the mass of the rollers generates a centrifugal force: the heavier the roller, the sooner it constrains the variator to open, and vice versa. These 15 g (per roller) weights therefore influence the moment when the transmission revs up, affecting the responsiveness and feel during acceleration.

Variator Adjustment

Choosing the right weight of rollers allows for adjustment of the engine's operating range. Lighter rollers promote a higher RPM and quicker acceleration, while heavier rollers limit the RPM for a smoother response at low speeds. Tailor your choice based on your urban usage and the scooter's mapping.
