Reinforced Racing clutch kit from Polini. The Italian manufacturer provides the amplified set ready complete with 5 friction plates, 4 steel plates and springs. As is general with reinforced clutches, this one uses an additional friction disc and steel disc. All discs are made a bit thinner, but together increase the friction surface overall. The result is higher power transmission and less slip. The factory clutch only has 4 friction discs and 3 steel discs.

Suitable for Derbi / Piaggio geared bike engines EBE, EBS, D50B0.
