clutch spring kit Top Racing 3x3 for original clutch d=105mm for Minarelli

Generally, tuned engines develop their power only at a higher RPM, and the engine loses power at low revs. This often makes for poorer drive. To get around this, this set includes Top Racing clutch springs with different strengths for standard clutches. 3 sets of clutch springs are supplied. The colours are described in a small, enclosed instruction booklet regarding the respective hardness . . Warning: Only match series 2-shoe clutch for Minarelli. (With 105mm diameter)
