variator weights adjustment set Polini 15x12mm - 2.5-4.0g 242.400

4 weight sets for tuning the variomatic (2.5, 3, 3.5, 4g). Simply fit the weights into the casing. The set allows you to tune you scooter perfectly. For long term use we recommend pre-encased weights. To tune, begin with the heaviest weights and keep going down a set until the engine revs up and slows down equally.
