Browse more variator and roller weight options to find parts that suit how you ride, your engine setup, and your body weight.

Weight Options

The kit includes weights from 7g to 18g, with three rollers of each weight. Because the colors are coded by weight, it is easy to try different combinations and see which works best on your scooter. Pairing neighboring weights in equal numbers gives you half-gram steps, which opens up more ways to fine-tune the setup.

Setting Up the Variator

To get the most even result, spread the roller weights evenly around the variator. Place each group of three rollers at 120-degree intervals, and make sure every roller pocket holds a different weight. Arranging them this way helps reduce vibration and lowers the risk of damaging the variator.
