POLINI Evo-Slider Contrast Spring YAMAHA T-MAX 500

The POLINI Evo-Slider contrast spring is an essential component for optimizing the operation of the variator group, especially in the presence of high-performance transformation kits. This spring is designed to handle the increase in power and torque, ensuring a more efficient response from the rear movable pulley.

Thanks to a higher load compared to the stock spring, the available variants offer a 10% increase for blue springs (MaxiScooters), 7% for white springs (Scooters 50), and 15% for blue springs (Scooters 50). It is important to note that the use of springs with a higher load must be carefully evaluated, as excessive load can compromise the transmission, increasing belt wear.

The Evo Slider, made from special wear-resistant and self-lubricating material, allows the spring to slide smoothly during the variator shift excursion, maintaining a constant torque. This innovative design helps improve the efficiency of the transmission system, ensuring optimal performance.

For proper installation, it is essential to follow the specific instructions, paying attention to the positioning of the convex side of the spring. Before proceeding with the replacement, it is advisable to check the condition of the transmission belt and the proper functioning of the entire variator group.
