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. AMA National Land Speed Records requires two passes the same calendar day in opposite directions over a timed mile/kilometre while FIM Land Speed World Records require two passes in opposite directions to be over a timed mile/kilometre completed within two hours.[1] These are special or modified motorcycles, distinct from the fastest production motorcycles. The first official FIM record was set in 1920, when Gene Walker rode an Indian on Daytona Beach at 104.12 mph (167.56 km/h). Since late 2010, the Ack Attack team has held the motorcycle land speed record at 376.36 mph (605.69 km/h).
