Original Minarelli 50 2-Stroke Scooter Clutch Springs Polini

Polini clutch spring sets for the original clutch.
Tuned engines deliver more power at high RPM and lose power at low RPM. If the clutch springs are not replaced with stiffer ones, acceleration worsens.

The stiffer Polini spring set causes the clutch to engage later, allowing you to skip the low-power RPM range and significantly improve acceleration.
It is also recommended to change the springs when installing a higher performance exhaust pipe! Choose the spring stiffness according to the level of engine tuning
