Daredevil motorbike rider Seth Enslow has smashed the world record for the longest distance jumped on a Harley-Davidson.
He managed a leap between ramps of 55.99 metres - easily beating Bubba Blackwell's previous world record of 47.85 metres set in Las Vegas in 1999.
The stunt took place at Barangaroo, on Sydney harbour, today and is measured in feet because the previous records have been set in the US.
Asked if Enslow would now try to push the record further in future, a spokesman for Harley-Davidson told AAP: "I'd say so."
"That magical 200 feet mark is not far off and he was pretty comfortable today."
The stunt was 12 months in the planning and Enslow chose Australia for the location because he's got good mates here, the spokesman added.
His bike was pretty much a standard Harley-Davidson, apart from modified suspension.
In a previous attempt at the record, in an indoor arena in the US, Enslow injured himself badly, tearing a number of ligaments in his shoulder.
