The rollers play a key role in managing engine speed and power delivery. By replacing the original rollers with this set, you can adjust the variator's opening curve: lighter rollers promote quicker acceleration, while heavier rollers delay the opening to favor thrust. This POLINI set allows for fine-tuning to optimize scooter behavior according to your riding style (starting, acceleration, cruising speed).

Simple installation and essential for any transmission adjustment: check compatibility with your machine's pulley/belt assembly before installation. Product delivered as a set, perfect for a complete variator repair.
