POLINI Contrast Spring 2 Stops Vespa 125 Primavera 4T 3V

The POLINI contrast spring with 2 stops is an essential component for the proper functioning of the variator group, especially in the presence of high-performance transformation kits. This spring is designed to ensure an optimal response from the rear movable half-pulley, helping to prevent belt slippage and improve the overall efficiency of the system.

POLINI springs offer increased loads compared to standard springs: 10% more for blue springs (MaxiScooters), 7% for white springs (Scooters 50), and 15% for blue springs (Scooters 50). It is important to note that the use of springs with increased load must be carefully evaluated, as excessive load can compromise power transmission and increase belt wear.

The spring is equipped with an EVO SLIDER, made from special wear-resistant and self-lubricating material, which allows for smooth and consistent movement during the variator shift travel. This innovative design reduces friction and improves the component's lifespan.

For installation, it is necessary to carefully follow the instructions, ensuring to check the condition of the transmission belt and the proper functioning of the entire variator group before proceeding with the spring replacement.
