The world record for the "World's Fastest Triumph" may soon be shattered as Tourist Trophy (TT) Legend, Guy Martin has set a new speed record at the Bonneville Salt Flats with 274.2 mph.

Martin piloted the Triumph Infor Roket Streamliner and achieved a top speed of 274.2 mph during morning practice runs. The current record has stood for 46 years at 245.667 mph (official) [264 mph (unofficial) set by Bob Leppan with the Gyronaut X-1].

“It’s good and we are moving in the right direction, but it is just one step on the way to what me and team are here to do," said Martin.

The team has just completed five days of testing and is due to return to Bonneville in the last week of August, for Speed Week, to make an official attempt at the world record for 'World's Fastest Triumph'. It will also attempt to break the 'Land Speed Record on Two Wheels', held by Rocky Robinson since 2010 riding the Top Oil-Ack Attack streamliner. The Land Speed Record on Two Wheels currently sits at 376.363 mph (605.697 km/h). The Triumph Infor Roket Streamliner team plans to potentially break the 400mph (643.74km/h) barrier. Triumph is looking forward to holding the title of ‘World's Fastest Motorcycle’ again, with its last stretch being between 1955 to 1970.

The Triumph Infor Rocket features a carbon Kevlar monocoque frame with two turbocharged Triumph Rocket III engines. Both engines produce a combined output 1,014 PS at 9,000 rpm and are fueled by methanol. The motorcycle measures 7,772mm long, 609mm wide and 914mm tall.

The bike itself competes in Division C (streamlined motorcycle) of the land speed record categories.
