CRANKSHAFT FULL SHOULDERS POLINI
Compatible with: Vespa 125 2T Primavera
125 2T ET3 Primavera
The crankshaft is not approved for road use.
The shape of the circular cleavers drastically reduces the internal turbulence in the crankcase, increasing the compression of the gases transmitted to the head for the combustion phase.
Balancing is achieved by using tungsten inserts and aluminum caps to reduce volumes.
The shaft is perfectly balanced and guarantees the maximum achievable performance.
The crankshaft increases the stroke to 54 mm and the connecting rod is machined from solid with a distance of 105 mm.
- Connecting rod length: 105 mm
- Cone: 20 mm
- Stroke 54 mm
ATTENTION: For the correct assembly of the shaft, we recommend that you contact a competent and authorized workshop or an experienced and qualified mechanic.
NOTE: In order to use the crankshaft it is mandatory to bore the crankcase.
NOTE: The crankshaft must be used exclusively in combination with the reed valve cylinder kit Cod. 140.0227 available in our store.
