Mopeds and motors scooters are more than just practical transportation alternatives -- they are a lot of fun. My favorite models to ride are the 125cc scooters. They're fast enough to be fun, but small enough to be easy to manhandle. For younger riders, a 125cc scooter is plenty powerful enough for in-town riding, but for stunts or tricks, you might want to stick with 50cc mopeds or scooters -- they'll give you the same level of maneuverability as 125cc's on a larger person.
