Article information
POLINI EVOLUTION CRANKSHAFT FOR VESPA 125 PRIMAVERA ET3 - SMALL FRAME
The Evolution "Full Masses" crankshaft can only be used if the engine is fitted with the new cylinder with lamellar intake, reference 140.0227.
The shape of the circular masses radically reduces turbulence inside the crankcase by increasing the compression of the gases transmitted to the cylinder head during the explosion phase.
Balancing is achieved through the use of tungsten inserts and aluminum caps to reduce volumes.
To be able to use the new crankshaft, the crankcase must be bored.
The Polini Evolution "Full Masses" crankshaft increases the stroke to 54mm. The connecting rod is pulled from a single block with a center distance of 105mm.
The assembly of this new product makes it possible to reach a displacement of 152cc.
