Description

Dial in your CVT performance with the Polini 16x13 Roller Weight Tuning Kit — a comprehensive four-weight set that lets you test and optimize your scooter's acceleration, top speed, and power band without committing to a single weight. Whether you're chasing snappier off-the-line pull or a higher cruising RPM, this kit gives you the data to find your sweet spot.
