Polini clutch springs are engineered for tuned engines that peak at higher RPMs.

Stock clutches struggle to engage effectively in the lower rev range, causing sluggish acceleration. These stiffer springs bridge that gap, allowing your scooter to pull harder from a standstill while your engine builds to peak power. Essential upgrade when pairing a performance exhaust with engine modifications.

This set includes three springs at 1.9mm thickness with +50% increased hardness, finished in distinctive yellow.

Direct fit for Piaggio and Vespa standard clutches.
