You ever wonder what would happen if you shoehorned a 500 hp Dodge Viper V-10 motor onto say.. a motor cycle? Well, wonder no more.

Dodge claims the concept motorcycle (that actually has 4 wheels) can reach speeds in excess of 400 mph. When pressed by pundits, however, they backed that off to 300+. This month's Popular Science (April Edition) has a nice article on the bike. Pundits at the magazine think that fear and drag are the only real limitations of this bike. Plus, based on how the driver has to sit, his arched back might act as a wing, ripping him right off the bike at high speeds. Isn't that a pleasant thought?
