The POLINI Evo-Slider contrast spring is an essential component for optimizing the performance of the variator group, especially in the case of significant engine upgrades. This product is designed to tackle the transmission challenges that may arise after the installation of high-performance transformation kits. With a higher load compared to the stock spring, it offers a 10% increase for blue springs (MaxiScooters), 7% for white springs (Scooters 50), and 15% for blue springs (Scooters 50).
The Evo Slider, made from a special wear-resistant and self-lubricating material, allows the spring to slide smoothly, reducing friction and improving the efficiency of the transmission system. During the shifting excursion, the movable half-pulley slides axially and rotates around the fixed half-pulley, generating a variable torque on the spring. This innovative design is intended to ensure a constant and reliable response, which is crucial for maintaining optimal power transmission.
It is important to note that the installation of a spring with an increased load should only occur when strictly necessary, as excessive load can compromise the lifespan of the transmission belt and reduce overall efficiency. Before proceeding with the replacement, it is advisable to check the condition of the belt and the proper functioning of the entire variator group.
