I'm a newb, but have been obsessing about Vespas and will give it a go.
-Same seat height
-Large frame is longer, wider and heavier
-In USA, large frame engine will always be larger
-Large frame has higher top speed
-Large frame can't fit full face helmet under seat
-Everything else being equal, small frame gets better fuel economy
-Large frame had larger wheels, up to a certain year…when?
-No kick-start on large frame? Is that right?
-Are all the large frame USA market water cooled?
-Did I miss anything?
6/19 edit:
Update from replies:
-Only large frame gets handlebar shake, happens at around 30 mph
-Large frame has more room for a passenger
-Large frame top speed is over 60 mph
-Glove box is smaller but stays cool when riding (large frame models the glove box heats up as it's next to the radiator).
6/21 edit:
-Small frame has cable actuated rear drum brake. Large frame has hydraulic disc rear brake.
