Get ready for a wildcard! The Honda Grom looks like a motorcycle (albeit a tiny one), smells like a motorcycle, and works like a motorcycle, so we’re calling it one and including it. It’s street-legal, too, so technically it rightly deserves its spot on this list. With a 124cc engine you can’t take it on the freeway, but you sure as hell can terrorize the city streets, go-kart track, or local skate park! Honda can’t seem to keep enough of these things in dealerships and we know why: they’re really cheap and an absolute blast.
