Variator Polini Hi-Speed Piaggio / Vespa 125 4-Stroke 3V IE

Polini Hi-Speed Variator Polini for Piaggio / Vespa 125-150 4-Stroke 3V IE.

Does your scooter launch and then fall short off the line? With the Polini Maxi Hi-Speed Variator, you will notice more powerful acceleration, increasing pulling force at launch thanks to the contra spring with 7% greater stiffness, providing a more immediate response and extra thrust that makes the difference at every traffic light.

The secret lies in the unseen details: the pin is made of special case-hardened, tempered, and ground nickel-chromium steel, which translates into greater strength and durability. The roller tracks receive a polishing treatment that improves sliding, and the rollers are coated with a new blend of nylon and aramid fibers, high-performance materials that withstand intensive use better.

Its patented lubrication system: it incorporates an internal pouch that functions as a grease reservoir and an internal spring that distributes the grease constantly over the pin, even under the harshest conditions. This maintains consistent performance over time, reduces maintenance, and an adjustment washer is also included for installation between the pin and the fixed half-pulley.
