Polini clutch springs deliver the performance edge tuned engines need.

When modifications push power delivery to higher RPMs, low-end acceleration suffers. These springs bridge that gap, engaging the clutch earlier to restore responsive throttle response across the entire rev range — essential when pairing your engine with a performance exhaust. Set includes three springs engineered for Minarelli 107mm standard clutches.

The 1.8mm thickness and +50% hardness rating (yellow) are calibrated to optimize power transfer without compromising reliability. A performance upgrade that transforms how your scooter accelerates from a standstill.
