The name pit bike originated from the use of a Honda Z50. The ride around the pit areas of dirt bike races and race events across the United States. The fairly cheap price and the mobility of these bikes made them easy to use. When at racing events. Popular dirt bike movies like the 2001 Crusty Demons of Dirt 3 show. How these small motorcycles can be used to do things other than just riding back and forth in the pits. A part of this movie shows people taking huge bicycle jumps on a Z50 in someone’s back yard.
