This pit bike mod is really an extension of Chris Harris’s Space Saver Experiment. The theory is that a car that is fast around a track isn’t necessarily fun. How fun a car is depends on its power to grip ratio. Basically it’s more fun if it’s easy to kick the back end out. These guys replaced the rear tire of their tiny pit bike with plastic tricycle wheels and round about drift madness ensues.
**NSFW WARNING** The Papa Roach soundtrack has a couple of bad words.
