The last cylinder Polini produced for the “Evolution” series before they came out with their “Big Evo 2010”: Polini 70cc Cylinder Kit “Evolution 3”, 10mm, MBK Nitro / Aerox (Minarelli horizontal LC).
The kit includes:
– 70cc Aluminium Cylinder “Evolution 3”, with 6 transfer ports and bridged exhaust port
– One-Ring Piston, 10mm pin
– High Compression Modular Cylinder Head with detachable combustion chamber
– Gasket Kit for mounting and adjusting squish clearance
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”, 10mm, MBK Nitro / Aerox is not street-legal.
Available here as 10mm piston pin version.
