Special Price €38.40 Regular Price €48.04The POLINI Evo-Slider contrast spring is an essential component for optimizing the performance of the variator group, especially following modifications that significantly increase engine power. This product is designed to ensure proper functioning of the rear movable half-pulley, preventing belt slippage and ensuring a more responsive acceleration.
The POLINI contrast springs offer an increase in load compared to the stock springs: 10% for blue springs (MaxiScooters), 7% for white springs (Scooters 50), and 15% for blue springs (Scooters 50). It is important to emphasize that the use of springs with increased load should be reserved for cases where it is truly necessary, as excessive tension can compromise the performance of the transmission and increase belt wear.
The Evo Slider, made from a special wear-resistant and self-lubricating material, allows the spring to slide consistently, improving system efficiency. During installation, it is crucial to follow the specific instructions to ensure proper assembly and optimal operation.
