High-quality reproduction of the crankshaft type for the old Vespas with nose piston and direct intake at the cylinder. This was used in the vehicles which for the first time had a three-digit chassis prefix (VNA)
  • inlet type: slot-controlled cylinder intake
  • crankshaft type: Full cheek
  • stroke: 57.0mm
  • connecting rod: 105.0mm
  • piston pin Ø: 15mm
  • connecting rod journal lower Ø: 18mm

crankshaft in very good reproduction quality, Made in Italy. Corresponds in the dimensions exactly to the original.

NOTE: The crankshaft of the VNA models is available with 54mm and 57mm stroke.
Ex works the VNA models were always only available with 54mm stroke. The 57mm crankshaft can be used as long stroke shaft for a solid O-tuning. For this purpose, compensate the additional stroke of 3mm with a 1.5mm thick head gasket.
