Vespa does make mopeds, the Ciao being the the most popular still.
Unfortunately they quit making the Grande by the 80's. They are still around, and I would say to get one if the right deal comes along.
Despite appearing to be heavier than they are, they are pretty quick given the variator transmission.
I won't part with mine. Unless I found a real cherry low mileage one. Then I probably wouldn't ride it.
I think I'll keep mine...
