Gregory Dunham, from California's Stockton, built the world's biggest motorcycle, which was officially recognized by the Guinness Book of World Records.
The beauty shop owner said he created the monster bike because his friends said it couldn't be done and he wanted to prove it could.
Greg Dunham spent three years in his workshop crafting this 11 feet tall, 20 feet long monster bike which was powered by a 8.2 litre (V8 engine and has tyres that are 1.88 m tall.
Even though, the 6,500-pound motorcycle with a pricetag of $300,000 is totally rideable (watch video below), we think, very few people would like to buy the world tallest motorcycle.
