POLINI Contrast Spring YAMAHA X-MAX 125

The POLINI contrast spring is an essential component for optimizing the operation of the variator group, especially in high-power situations resulting from advanced transformation kits. This spring is designed to tackle transmission challenges, reducing the risk of belt slippage and ensuring effective resistance to the movement of the rear movable sheave.

The available springs offer an increase in load compared to the stock springs: 10% for the BLUE version (MaxiScooters), 7% for the WHITE version (Scooters 50), and 15% for the BLUE version (Scooters 50). It is important to note that using a spring with a higher load must be carefully evaluated, as optimal performance is generally achieved with lower load springs, which allow for more efficient power transmission.

Additionally, the contrast spring is equipped with the EVO SLIDER, a special wear-resistant and self-lubricating material that ensures smooth and consistent movement during the variator's shift travel. This innovative design helps maintain the efficiency of the transmission system, reducing wear and improving the overall performance of the vehicle.

For correct installation, it is essential to follow the specific instructions, ensuring to check the condition of the transmission belt and the operation of the variator before proceeding with the spring replacement.
