The rollers play a key role in the behavior of the variator: by modulating their mass, you adjust the acceleration curve and the shift point. This POLINI set offers a neat finish and suitable tolerances for smooth riding. Ideal for replacing worn rollers or for testing different weights during fine-tuning of the transmission.

Before installation, check compatibility with your variator and the condition of the running surfaces. Always replace rollers with a complete set to maintain optimal drum balance and avoid premature vibrations.
