It's official now, the Guinness Book of World Records has confirmed this massive motorcycle as the world's heaviest.

This beast was built in Zilly, Germany by Harzer Bike Schmiede, and dubbed, "Led Zeppelin".

It weighs just over 4 1/2 tons, and measures 17 feet, 4 inches long, and 7 feet, 6 inches tall. The engine alone weighs 1.8 tons, and comes from an old Russian tank.

The motorcycle is the design of Tilo Nieber, who has applied for a license to drive the thing down German roads.

Instead of designing this as a trike (to keep it upright), they cleverly added a sidecar to preserve its status as a motorcycle
