Polini Evo Slider 4,5 +8% Compression springRef : POL00105A / 1011854

The POLINI Evo Slider +8% push spring is designed for Piaggio engines and targets urban riders looking to enhance and refine their transmission response. Positioned between the clutch and the variator, it modulates the pressure applied to the jaws and contributes to a more controlled rev-up without altering the roller settings.

• Compression rate: +8% — increased load resistance
• Superior resistance promoting a more linear twisting of the spring
• Evo Slider technology: anti-wear treatment and self-lubrication to limit friction
• Contributes to the longevity of the transmission by reducing wear related to stress
• Optimization of variator behavior — useful during preparation or replacement of components

Easy to install for DIY enthusiasts familiar with disassembling primary transmissions, this spring integrates discreetly while providing a more consistent load-bearing capacity. Ideal for urban commutes, it is particularly suited for 50cc scooters and Piaggio models.

Main compatibilities: PEUGEOT KISBEE 50 4T (2025), PIAGGIO TYPHOON 50 E2 (C501) (2017), APRILIA SR 50 R E4 (2017).
