Even if titles like "Most Powerful Production Motorcycle in the World" don't last forever, earning one at all is quite an achievement. The current title holder is the Vyrus 987 C3 4V ($70,000 and up). Ditching traditional front forks for a unique design that's steered via a center hub, the C3 4V claims its title through a combination of an ultralight curb weight of only 339 lbs. and a Ducati-made, supercharged 1198cc V-twin engine pumping out 211 horsepower. Add in an agressive body, jet fighter-inspired lights and dashboards, and world-class Brembo brakes, and you've got one exclusive two-wheeled rocket.
