Description


The Evolution2 kit is the most powerful Polini cylinder kit for case controlled engines. It has been specifically designed for the 135cc VPI racing class in Italy.
The housing has to be unscrewed to accept the cylinder base (64x20mm). The cylinder uses the standard stroke and connecting rod length (51mm, 97mm) and can therefore be used with any conventional racing crankshaft. Special feature of the EVO2 kit is the modified exhaust flange. This was designed so that the cylinder can also be used mounted rotated, i.e. the exhaust system looks forward in the direction of travel. An appropriate exhaust is then of course a prerequisite. With 58mm bore it has real 135cc. The one-piece rectangular and very wide exhaust offers best conditions for high performance with a wide power band.
