3rd generation of Polini's "Evolution" cylinders, the last one before the release of the new "Big Evo 20120" series.
The "Evolution 3" is based on the "Evolution 1" cylinders, but some features were modified, such as the redesigned two-part "bridged" exhaust port.
As a 70cc "Hyper Racing" kit, it is more powerful than its predecessors and, in combination with the right components (21-28mm carburetor and "Hyper Racing" exhaust), it can reach 18/19hp.
Note: the Polini 70cc Cylinder Kit "Evolution 3" Piaggio NRG / Runner is not street-legal.
