cylinder kit Polini Big Evolution 94cc 52mm bore 44mm stroke for Minarelli AM

Polini promises atomic power with the Big Evolution series. More power is theoretically almost impossible to realize. With an incredible 94cc capacity you have almost reached the limit. To make this capacity possible, the cylinder has to be combined with a 44mm stroke crankshaft. A special manufacturing process made it possible to produce the special one-piece cylinder head. This is necessary to meet the thermal demands of this performance and to dissipate the heat optimally. High-end tuning at the highest level.

88% capacity increase requires the adaptation of other components such as crankshaft, exhaust system, clutch and of course fuel conditioning.
