The POLINI clutch spring kit (manufacturer reference 245.012), designed for Minarelli engines, is aimed at urban scooter riders who want to fine-tune their clutch behavior. It offers a range of adjustments to adapt the rev-up, reduce slipping, or stiffen the engagement depending on usage and variator setup.
Kit contents — 12 springs:
Each pair of springs allows you to explore different compromises between clutch softness and engine responsiveness. Ideal for fine-tuning on urban roads, this kit facilitates quick testing during preparation or maintenance to achieve the desired behavior at startup and during acceleration.
Compatible with many 50 cc scooters equipped with Minarelli engines — for example, PIAGGIO NRG 50 DD, PEUGEOT SPEEDFIGHT 4 50 2T, and YAMAHA AEROX R — it is a practical accessory for any rider looking to customize their clutch without irreversible modifications.
