POLINI Evo Slider Push Spring +40% (Ref. 243.094)
Designed for urban scooters, this POLINI push spring enhances clutch pressure regulation for a sharper handling of the drivetrain. Ideal for those looking to optimize the variator and transmission without heavy modifications, it provides a more consistent response during acceleration and city riding.

• Compression Rate: +40% — increased pressure for a more sustained push action
• Evo Slider Technology: wear-resistant treatment and self-lubrication to minimize friction and wear
• Improved variator performance thanks to a more linear spring twist
• Contributes to the longevity of the transmission by reducing jolts and slips
• Replacement part designed for urban use and light tuning of the transmission system

Easy installation for both amateur mechanics and workshops: this spring integrates directly onto Minarelli engines equipped with the compatible system. Particularly suitable for urban 50 cc models such as Yamaha Aerox R (SA421), MBK Ovetto 2T One, and Keeway Matrix 50 Racing Sport. Keep in mind that this component enhances regulation and durability; for optimal variator tuning, pair it with appropriate rollers and weights.
