Clutch springs Honda / Piaggio / Vespa 125/250 Polini

Kit of 3 Original Clutch Spring Games

Tuned engines deliver more power at high RPM and lose power at low RPM. If the clutch springs are not replaced with harder ones, acceleration worsens.
The set of harder Polini springs makes the clutch engage later, which allows you to skip the low-power RPM range and significantly improves acceleration.
It is also recommended to change the springs when installing a higher performance exhaust pipe!
