POLINI CONTRAST SPRING HONDA FORESIGHT 250

The POLINI contrast spring is an essential 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, reducing the risk of belt slippage and ensuring that the rear movable pulley can effectively counteract the movement of the pulley mounted on the crankshaft.

POLINI contrast springs offer a load increase compared to 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 use the spring with the increased load only when necessary, as excessive load can trap the belt between the pulleys, increasing wear and reducing transmission efficiency.

Additionally, the spring is equipped with the EVO SLIDER, a special wear-resistant and self-lubricating material that allows for constant smoothness during the variator shift travel. This system improves the response and durability of the component, ensuring optimal performance over time.

For proper installation, it is essential to follow the specific instructions, paying attention to the wear state of the belt and the operation of the entire variator group.
