Roadog must be the most ridiculous motorbike ever built. It runs a huge watercooled car engine, has four pneumatic struts in order to keep it upright until the rider is properly seated, and is very hard to maneuver. It is more an oddity than anything else. Even the slightest lean left or right when standing still might mean you tip over, and then you will need at least four fully grown men to help you get it upright again!
