The guys at Parker Brothers Choppers are responsible for the awesome monstrosity that you see above – they call it the Huffy Green Machine and comes with an 80-cubic inch Harley Davidson Evo engine. Jeff Halverson explained: We had a Green Machine lying around the shop and we figured it would be a cool idea. It rides crazy and is fast as hell. If it wasn’t for the rear tires we could have had it DOT approved. The team is going for a Guinness record: the largest front wheel on a motorcycle trike.
