I own a 2012 Vespa 300 Super and a 2013 Zero S. I use the bikes fairly interchangeably and often ride an indicated 80 mph on the interstate with the Vespa which is about wide open. This is the second Vespa 300 I've owned and they have both been very good scooters. There's more storage in the Vespa with both a grocery hook and all that under-seat storage, and of course range isn't an issue. The Vespa uses premium gas, but it gets 55 mpg or so. Vespa has a 1-yr. warranty vs. a 2-year warranty with the Zero. Zero is over 2X the cost so the Vespa would be much cheaper to buy and ride. If I could lane split, either would be fine, but the Zero might be a little narrower. I find both seats just fine, but I think most people would prefer the Vespa seat. Coolness factor probably goes to the Zero, but I get lots of people asking about the Vespa too. I am used to riding fast, so I don't have any problem with the Vespa at highway speeds, but the Zero holds the line in windy conditions a little better. The Vespa has good acceleration and maneuverability too and you can turn on a dime because of the small wheels. They are both hard to beat for in-town riding. If money were a factor, I would probably just own the Vespa. It should be very dependable for many years. If I really never went on the interstate, I might be looking at a fuel injected Vespa 150 with a top speed of 62 mph or so, and in a pinch you could still go on the interstate and stay in the slow lane.
