Difference between revisions of "Motorcycle land speed record"

Revision as of 10:19, 25 July 2009

The motorcycle land speed record is the fastest speed achieved by a motorcycle on land. It is standardized as the speed over a course of fixed length, averaged over two runs in opposite directions.

First set, unofficially, by Glenn Curtiss in 1903, the first officially-sanctioned FIM record was not set until 1920. There was controversy over the 1930 record, when OEC claimed to be fastest, on the basis of a publicity photo taken before a Zenith went quicker. "It was quite a while before the controversy died down."

Jet-engine trike

The fastest record certified by the FIM is that set in 1964 by the jet-propelled tricycle Spirit of America. It set three absolute land speed records, the last at 526.277mi/h. While such records are usually validated by the Fédération Internationale de l'Automobile, the FIA only certifies vehicles with at least four wheels, while the FIM certifies two- and three-wheelers.

Piston-engine bike

The holder of the absolute record for motorcycles is the "fastest man on two wheels". All such records have been with piston-engine machines.
