Officially, four men, Rick Dozier, Bill Decker, Rob Moore and William Longest are holders of the world record for constructing and riding the world's longest motorcycle which is 29,3 feet long.
However, the motorcycle which you can see in following photos is claimed to be the new world's longest motorcycle with its length of 31,4 feet. It is allegedly constructed in Russia and it has 15 seats. Despite the fact that it has 15 seats, some are questioning the functionality of this bike and its ability to drive 15 people at once.
This huge long bike was built by Oleg Rogov. This record has been entered into Guiness books of records as well.
