Well, it looks like Vespa is going to be top scooter. Nice little machines. They have a unit body and the engine, transmission, and rear wheel are all in a neat little package. No sprocket chain. The design dates to the 1940's and it hasn't changed much over the years. You can get anything from 50cc's to 200cc's depending on how big you are and how fast you want to go. They are fairly easy to work on and don't give much trouble. I hear that in Italy they travel in swarms. After all, the name means "Wasp." It's a very cool ride. They are manufactured by a company called Piaggio.
