Harley-Davidson's famous racing boss Dick O'Brien was looking in the 1960s to strike back at Triumph and its 500cc twins that were winning Daytona.

How the Suzuki Hayabusa Changed Motorcycling Feb 15, 2024

The Suzuki Hayabusa broke cover in 1998 and shattered our perception of motorcycle performance at its 1999 introduction. Cycle World Technical Editor Kevin Cameron and Editor Mark Hoyer discuss the Hayabusa’s impact after 25 years, and how other bikes relate, like the Kawasaki ZX-11, ZX-12, and ZX-14, plus Honda CBR1100XX. Hoyer talks about what the bike was like to ride at the press introduction held in Spain at MotoGP race track Circuit de Catalunya, and “On-Road Touring” at 190 mph on Spanish freeways. Plus, record-breaking performance in the quarter-mile and its 194-mph top speed recorded by the CW radar gun, and how that brought about the “gentleman’s agreement” to limit peak speeds of motorcycles. Kevin talks turbos and the surprising things Suzuki did during development of the Gen III ’Busa. Strap your helmet on and tuck in!
