With enough power to put a smile on the face the most seasoned adrenaline junkie, the 2010 Vyrus 987 C3 4V ($100,000 and up) currently holds the title of the most powerful street-legal bike in production. Built with an impressively light 339-pound body, this supercharged Vyrus is fitted with a Ducati 1198 motor that cranks out 211 horsepower. The Vyrus 987 will also be available in two other flavors, including a 170hp base model weighing 359 lbs and a 184hp, 384-pound Spec R.
