Rocky Robinson and the ACK Attack do 547km/h

Twin Hayabusa engines, 900 horsepower, 547km/h...

Rocky Robinson has set a new motorcycle land speed world record. Riding his Team Top-1 ACK Attack streamliner at the Bonneville Salt Flats, he made an initial pass at 550.4km/h and a return pass of 544km/h, resulting in the new record (average) speed of 547km/h. The last record, which stood for 16 years, was set by Dave Campos in 1990 – at 515.2km/h.

During the Bonneville Speed Week this year, riders had a 17.6km course to work with, compared with only 8km last year. This provided an opportunity to mega-powerful machines like the ACK Attack, which incidentally is powered by twin Suzuki Hayabusa engines – producing a total of more than 900 horsepower, to really strut their stuff.

Here’s a list of who’s been going how fast (on two wheels) over the years:

1937 Ernst Henne BMW 500 274.494km/h

1951 William Herz NSU 500 289.681km/h

1962 Bill Johnson Triumph 650 361.410km/h

1966 Bob Leppan Triumph 650 395.362km/h
