How fast can a vespa go

The Vespa LX150 (150cc) will top out around 110kmh give or take on your weight, wind, grade of road etc.

As Dan said that's plenty fast enough. Even the 70cc version would be more than adequate, provided you didn't live in the hills of San Francisco :)

Hey Blinky

Basically it depends on the engine size or capacity of the model you are talking about...a 50cc model might get to around 45mph ( 72kmh).

A mid sized model such as a 70cc might do more like 55mph(88kmh).

There are also 150cc Vespa models that will do around 65mph(105kmh).

I'm not sure exactly that you'd want to be doing those higher sort of speeds on a scooter like a vespa...They really are just best for the small commutes like you mention, so i wouldnt get too worried about speed limits on them.
