I saw this Tomahawk V-10, the other day over at Yahoo.
Dodge introduced its Tomahawk V-10, 8.3-liter (505 cubic inch) concept motorcycle at the North American International Auto Show in Detroit on January 6, 2003. The superbike features independent four-wheel suspension, and its engine, borrowed from the Viper sports car, can propel the Tomahawk at speeds of nearly 400 mph, according to Dodge.
400 mph! Think of the bugs in your teeth 😯 Four wheel drive! Are they sure it is a bike?
Update: Dodge now have a proper website for the Dodge Tomahawk with photos, news, specs, etc.
