The heaviest motorcycle is the Harzer Bike Schmiede, built by Tilo and Wilfried Niebel of Zilly, Germany, which weighed 4.749 tonnes (10,470 lb) on 23 November 2007. A giant motorbike powered by a Russian tank engine has been recognised as the heaviest in the world.
It’s been dubbed the Led Zeppelin by creator Tilo Nieber, 39, who said: “You don’t get much more heavy metal than this.”
The four-and-a-half tonne machine has driven into the Guinness Book of Records as the heaviest motorbike in the world.
It is 17 ft 4 ins long and 7 ft 6 ins tall and the engine alone weighs 1.8 tonnes after the armour plating tank cover has been stripped off.
