One set of Polini clutch springs designed for Minarelli 107mm stock clutches.

Modified engines deliver peak power at higher RPMs, leaving a noticeable power gap at lower revolutions. This results in sluggish acceleration off the line. Polini clutch springs come in multiple tension ratings to fill that low-end power deficit and restore smooth power delivery across the rev range.

Essential upgrade when pairing with a sport exhaust system. This is the medium (green) variant.
