POLINI Evo-Slider Contrast Spring YAMAHA T-MAX 530

The POLINI Evo-Slider contrast spring is a fundamental component for optimizing the performance of the variator group, especially in the case of significant engine upgrades. This spring is designed to tackle the challenges posed by high torque and power transformation kits, which can cause belt slipping or poor responsiveness of the rear movable pulley.

The POLINI contrast springs offer an increased 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 use a spring with an increased load only when strictly necessary, as the best performance is achieved with springs that allow for optimal power transmission with the least possible load. The Evo Slider, made from special wear-resistant and self-lubricating material, ensures smooth and consistent movement of the spring during operation.

For correct installation, it is necessary to disassemble the transmission cover and follow specific instructions, paying attention to the position of the spring and the possible replacement of the transmission belt with a Polini in case of wear. This ensures efficient and prolonged operation of the transmission system.
