Malossi Variator 15x12mm 8,7gr - of 6 Universal Variator rollersRef : MAL00283A / 1007761

Set of 6 MALOSSI rollers 15x12 mm, weight 8.7 g per roller — a spare part designed for scooter variators. Made from CPT with a specific formula, these rollers replace the original components to readjust the gear shift timing and response of the two-wheeler. Complete set ready to be mounted for a restoration or fine-tuning of the centrifugal transmission.

Operation

The rollers act within the variator drum: under rotation, their mass generates a centrifugal force that pushes the rollers outward and alters the gear shift. The heavier the roller, the greater the centrifugal force, and the earlier the variator shifts up; the lighter it is, the more the engine can rev before locking. Choosing the right weight allows you to influence engine behavior (acceleration, RPM stability) without modifying the mechanics.
