The POLINI D.3.9 Evo-Slider contrast spring is a fundamental component for optimizing the performance of the variator group, especially in the case of advanced engine modifications. This spring is designed to handle the increased power resulting from transformation kits, ensuring a significant improvement in transmission management.
With an increase in load compared to the stock spring, the available variants include: 10% higher load for the blue spring (MaxiScooters), 7% for the white spring (Scooters 50), and 15% for the blue spring (Scooters 50). It is important to note that the use of springs with increased load must be carefully evaluated, as optimal performance is generally achieved with lower load springs, which ensure a more efficient power transmission.
The Evo Slider technology, made with special wear-resistant and self-lubricating materials, allows the spring to slide smoothly during operation, reducing friction and improving the longevity of the system. Before proceeding with the replacement of the spring, it is advisable to check the condition of the transmission belt and the proper functioning of the entire variator group.
