POLINI Roller Set 20 x 14.95 - 13.8 g (manufacturer reference 242.433)
Variator rollers designed for the urban environment and compact scooters. This POLINI set consists of 6 calibrated rollers for fine-tuning the CVT transmission. Ideal for riders who want to refine the gearing and behavior of the transmission without modifying the internal components.
These rollers allow for precise calibration of the transmission: by adjusting the weight of the rollers, you can influence how the variator revs up, affecting acceleration and the engine's operating range. When installed correctly, they integrate with the standard variators of urban scooters listed among the compatible models.
Examples of common applications: Vespa Sprint 125 3V (2025), Piaggio Liberty 125 S (2025), Honda SH 150 S (KF13, 2016). Check compatibility with your variator before installation.
