POLINI Contrast Spring HONDA SH 125/150

The POLINI contrast spring is a fundamental component for optimizing the performance of the variator assembly, especially in the presence of high-performance transformation kits. This spring, designed for the rear movable sheave, offers an increased load compared to the stock spring, with specific values: 10% for the BLUE version (MaxiScooters), 7% for the WHITE version (Scooters 50), and 15% for the BLUE version (Scooters 50).

The adoption of a spring with increased load is recommended only when necessary, as a spring that is too stiff can trap the belt between the pulleys, increasing wear and reducing transmission efficiency. It is essential to check the condition of the belt and the proper functioning of the entire variator assembly before proceeding with the replacement.

Additionally, the spring is equipped with EVO SLIDER, a special wear-resistant and self-lubricating material that allows for consistent smoothness during the variator's shift travel. This system improves engine response and ensures a smoother and more effective power transmission.

For correct installation, it is necessary to carefully follow the provided instructions, paying particular attention to the positioning of the EVO SLIDER and checking the belt.
