Previously Triumph has logged a best of 245.667mph with Bob Leppan clocking up an unofficial best of 264mph in the famed Gyronaut X-1.

The speed comes at the end of the week’s testing on the Bonneville Salt Flats with the official attempt at the near-400mph record happening later this month.
Guy said: “That’s the testing week for the Triumph streamliner over and it’s gone pretty much according to plan.
“I got the hang of steering the thing pretty quickly then it was a case of building the speed.
“Wind is the big thing out here, so it’s not a case of just jumping in a twisting the throttle. We chipped away and early on Tuesday morning we did 247.2mph, making it the fastest ever Triumph.
“Everyone was dead happy but that’s just one step to where we want to be. The current record is 376.36mph so there’s a way to go yet.”
Guy’s best time is impressive and does set the bar for Triumph so far, but as the Lincolnshire biker says, there’s a long way to go. With around a week to go the outift needs to find another 102.163mph in order to match the current record which was set six years ago.
The history of the task
Triumph has a history of breaking the land speed record, holding the title of ‘World’s Fastest Motorcycle’ between 1955 to 1970. The record-breaking Triumph Streamliners included: Devil’s Arrow, Texas Cee-gar, Dudek Streamliner and Gyronaut X1, the former achieving a top speed of 245.667 mph (395.28 km/h). Today’s record, held by Rocky Robinson since 2010 riding the Top Oil-Ack Attack streamliner, sits at 376.363 mph (605.697 km/h).
