This is the amazing Pinasco "Nordkapp" 160cc aluminium cylinder kit for Wideframe Vespas with 2-port engines.
The cylinder fits 125cc-150cc engines built from approx 1953 to 1959, please check with us if you are unsure.
The Pinasco cylinder is designed for the 57mm stroke crankshaft of the 150cc models, but a long stroke conversion is possible for even more power, this uses a 60mm or 61mm stroke crank!
When fitting the cylinder to a 125cc engine, the original 54mm stroke crankshaft must replaced with the 150cc (57mm) crankshaft.
We always recommend using a new crankshaft (Pinasco or Kingwelle).
The kit is designed to give maximum power low down in the rev range which is perfect when using the original 3-speed gearbox (a 4-speed conversion is available) and you can expect a top speed of 60mph+ and 10hp+ depending on your configuration, it's closer to 15hp when using a 61mm stroke crankshaft.

We recommend using the Polini CP23 carburettor.
