Pinasco full cheek crankshaft for reed valve intake on Vespa PK50 XL/XL2 - 51mm stroke, 97mm connecting rod

Full cheek crankshaft for use with a reed valve / direct intake. Cannot be used with the original intake control via the engine case.

Has the original stroke/connecting rod length of the 125cc models (51 mm/97 mm). The crank web on the Lima side is very small. This means that the overlap over the crankpin is relatively small. In conjunction with the very large bore in the crankpin, we would therefore only recommend this shaft for mild tuning.


Diameter of the crank webs:

  • Lima side Ø 82 mm
  • Drive side Ø 87 mm
