POLINI Contrasting Spring D.4.4 Evo-Slider PIAGGIO

The POLINI D.4,4 Evo-Slider contrast spring is an essential component for optimizing the performance of the variator in tuned engines. This spring is designed to provide a higher load compared to standard springs, with a 10% increase for blue springs (MaxiScooters), 7% for white springs (Scooters 50), and 15% for blue springs (Scooters 50). Thanks to its construction from special wear-resistant and self-lubricating material, the Evo Slider allows for consistent smoothness, reducing friction and improving the efficiency of the transmission system.

It is important to note that while using springs with increased load can be beneficial in specific situations, it is always advisable to use the spring with the lowest load that ensures optimal power transmission. Springs with excessive loads can cause premature wear of the transmission belt and compromise the overall performance of the vehicle. Before proceeding with the spring replacement, it is essential to check the condition of the belt and the proper functioning of the entire variator assembly.

For correct installation, follow the specific instructions, paying attention to position the Evo Slider as indicated. With the POLINI D.4,4 Evo-Slider contrast spring, every motorcyclist can experience a significant improvement in engine response and power management, making every ride a more enthusiastic and high-performing experience.
