Description


The Evolution2 kit is the most powerful Polini cylinder kit for chassis controlled engines. It was developed especially for the 135cc VPI racing class in Italy.
The case has to be removed to accommodate the cylinder base (64x20mm). The cylinder uses the standard stroke and connecting rod length (51mm, 97mm) and can therefore be driven with any conventional racing crankshaft. A special feature of the EVO2 kit is the modified outlet flange. This was designed so that the cylinder can also be used turned mounted, i.e. the exhaust system looks forward in the direction of travel. A corresponding exhaust is a prerequisite for this. With 58mm bore it has real 135cc. The one-piece rectangular and very wide diffuser offers the best conditions for high performance with a wide power band.
