POLINI roller weights set designed for the variator transmissions of urban scooters. These rollers measuring 25 x 14.8 mm with a calibrated weight of 18 g (set of 8 pieces) allow you to fine-tune your transmission to adapt the power curve and engine response to your riding style in the city.
POLINI rollers are designed for precise variator tuning: by changing the weight, you can adjust the variator's operating range to favor quicker acceleration in urban traffic or a more gradual increase in RPM according to your needs. Ideal for tuning trials and optimizing performance in the city without resorting to heavy modifications.
Examples of common models where these rollers can be used: ZONTES 368 K (2025), YAMAHA X-MAX 400 TECH MAX (2021), ZONTES 368 G ADV (2025). Check compatibility with your variator before installation.
