Special Price €29.90 Regular Price €37.37The 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, ensuring smooth and slip-free transmission.
The available springs offer higher loads compared to the stock ones: 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 use a spring with an increased load only when strictly necessary, as excessive tension can compromise the efficiency of the transmission and increase belt wear.
The spring is equipped with EVO SLIDER, a special wear-resistant and self-lubricating material, which allows for constant movement during the variator's travel.
For proper installation, it is essential to follow the specific instructions and always check the condition of the transmission belt.
