Description
Pinasco crankshaft suitable for Vespa Wideframe with headlight on the fender (so called lamp down / Faro Basso models). The shaft is suitable for 125-150ccm engines built between 1953-1959 with two overcurrent channels in the engine housing.
The 125ccm engines originally have only 54mm stroke. The Pinasco crankshaft can be converted to 150ccm and more with a corresponding cylinder.
The connecting rod has a modern needle bearing and can therefore be used with an oil/petrol mixture ratio of 1:50.
Ideal for the Pinasco Nordkapp cylinder.
- stroke: 57mm
- conrod length: 110mm
- bearing: needle bearing top and bottom
