The fastest road-registered motorcycle on the planet is a Suzuki Hayabusa Turbo that hit 271.821mph (437.453km/h) for flying 1/4 mile.
The record was one of many set at the recent Straightliners Autumn Top Speed Weekend at Elvington Airfield, North Yorkshire, including fastest toilet, shed, trike and shopping trolley.
Even though the ‘Busa is road registered and insured, it’s not exactly stock.
The record-setting bike has a 1547cc engine with bigger pistons and output of more than 1000bhp (745kW). A stock Hayabusa has a 1340cc inline four with 197bhp (143.kW).
The Hayabusa is owned by Sean Mills of Big CC Racing, Wokingham, and was ridden by Phil Wood.
“I went out for a ride last week and found myself laughing at the bizarre thought that I was effectively ridding a motorbike with the similar power to a super sportscar such as Bugatti Veyron,” Phil said.

French rider Katy Calmon smashed the FIM 500cc record of 103.913mph (167.233km/h) by blasting a prototype to 127.045mph (204.482km/h).
