I want to point out that a lot of the discussion points in that video are around the LT version which is not available in the States. The LT was specifically designed to get around European motorcycle licensing laws so that you could ride it with a car license, something I would strongly discourage anyone from doing. So the versions available over here have the original distance between the front wheels (closer than the LT) and no foot brake. As far as licensing in the USA goes most States require a regular motorcycle license and a few require a 3 wheel endorsement (such as my own WA). Only California gets away with a regular car license but that is more of an accident than by design (and it’s kind of a gray area). There is also a 500cc version available (which is what I have). In Europe it’s branded as the Gilera Fuoco but here they just called it the Piaggio MP3 500.
Just to clarify, there is no manual clutch or shifting in any of the models. I know what Jeff meant but his comment could be misinterpreted. My take on it is the 250 model is fine for in town use. If you think you will be doing longer journeys you will be happier with the 400 or 500. If you do go for a 250 be aware only the newer models have a 14″ rear wheel. Earlier models had a 12″ wheel and folks were only getting 2 to 3 thousand miles on that. A 14″ (which the 400 & 500 have) is good for at least 6k.
This I think is a better review.
