POLINI Contrast Spring PIAGGIO 500-400

The POLINI contrast spring is a fundamental component for optimizing the operation of the variator group, especially in the presence of high-performance transformation kits.

This spring is designed to handle the increase in power and torque that can be achieved with more pronounced modifications.

The POLINI springs offer higher loads compared to the stock springs: 10% for the blue spring (MaxiScooters), 7% for the white spring (Scooters 50), and 15% for the blue spring (Scooters 50).

It is important to note that the use of springs with increased load should be reserved for cases where it is truly necessary, as the best performance is achieved using springs that allow for optimal power transmission with the least possible load.

The installation of the POLINI contrast spring is straightforward and requires careful adherence to the assembly instructions, thus ensuring the correct functioning of the transmission system.

Additionally, the EVO SLIDER, made from special wear-resistant and self-lubricating material, allows the spring to slide consistently, further improving the efficiency of the variator.
