clutch spring kit Polini sport 105mm for Minarelli P.13382

Tuned engines generally develop their power higher in the rev range and the engine can lose performance at lower revs, meaning poor drive. To combat this lack of performance at lower revs, Polini offer this set of clutch springs in various weights for standard clutches. You receive 3 sets of clutch springs with corresponding colours for the weights, which is laid out in the instrutction manual.
