Triumph Gyronaut X-1 Makes First Appearance In 42 Years At Pebble Beach

The Triumph Gyronaut X-1 is set to make its first appearance in 42 years at Pebble Beach.

In 1966 the Gyronaut X-1, with two Triumph Bonneville engines, tore up the track at the Bonneville Salt Flats. The bike achieved average speeds over 245 miles per hour, setting the world's record for motorcycles and earning the title as the "World's Fastest" bike from 1956 through 1970. Those who appreciate motorsports will be pleased to know the famed bike will be appearing for the first time in 42 years at Pebble Beach as one of the features of the Rare Antique and Classic Motorcycles for sale and online auction.

The Gyronaut X-1 looks more like a futuristic car than a bike with the long, slim body and cockpit. However, that was the point. The design team responsible for the "World's Fastest" on the planet built it to be fully aerodynamic, according to Motorcycle Cruiser, and it worked.

The bike was built during one of the most exciting periods in history by Bob Leppan, Alex Tremulis and Jim Bruflodt, according to The bike featured two 650cc Triumph engines fueled by alcohol and mounted behind the cockpit, a chromoly frame, rigid rear wheel and hinged front wheel. Power output was about 110 bhp at 7,300 rpm.
