Malossi Variator 15x12mm 4,8gr - of 6 Variator rollersRef : MAL00278A / 1007753

Set of 6 MALOSSI rollers 15x12 mm, unit weight 4.8 g – manufacturer reference 66 9417.E0. Designed for the variators of urban scooters, these rollers are made of CPT with a specific formula developed by Malossi. They provide a high-quality technical replacement for the original and a simple solution to fine-tune the response of your CVT transmission.

Operation

When rotating, the roller generates a centrifugal force that pushes the variator's cam. The weight of the rollers influences the moment when the variator changes gear: lighter rollers delay the RPM increase and promote responsiveness, while heavier rollers hasten the locking and enhance acceleration. These Malossi rollers allow you to adjust the engine behavior and acceleration curve according to your urban usage.
