I've never seen this anywhere I've traveled...apparently ATV's - 4 wheelers - are street legal here in Sioux Falls. Every once in a while, you'll see a couple of guys ride by on Honda 250's tricked out with street tires and a slightly wider stance.
This is nuts. Have you ever driven one of these pigs? They are made for the dirt and handle accordingly. They ride the best when allowed to slip a bit in the corners and power the back end around. I cannot imagine how bad they are to drive on pavement.
