POLINI Contrast Spring HONDA SH 125/150

The POLINI contrast spring is a fundamental component for the proper functioning of the variator group, particularly in situations of high power increase. This spring is designed to fit transformation kits that require greater torque and power, reducing the risk of belt slippage. POLINI springs offer a higher load compared to standard ones: 10% for blue springs (MaxiScooters), 7% for white ones (Scooters 50), and 15% for blue ones (Scooters 50). It is important to use a spring with an increased load only when strictly necessary, as excessive tension can compromise the transmission and increase belt wear.

Additionally, the spring is equipped with the innovative EVO SLIDER, made from special wear-resistant and self-lubricating material, which allows for smooth and consistent movement during the variator's travel. This system enhances operational efficiency, ensuring optimal performance.

For installation, it is necessary to remove the transmission cover and follow the specific assembly instructions, paying attention to the correct position of the spring and the possible replacement of the belt with a POLINI model in case of wear.
