The Suzuki Hayabusa (GSX1300R) is a world leading sport bike motorcycle made by Suzuki since 1999. It immediately won acclaim as the world’s fastest production motorcycle, with a top speed of 188 to 194 miles per hour (303 to 312 km). Hayabusa is Japanese for “peregrine falcon”, a bird that often serves as a metaphor for speed due to its vertical hunting dive, or stoop, speed of 180 to 202 miles per hour (290 to 325 km/h), the fastest of any bird. In particular, the choice of name was made because the peregrine falcon preys on blackbirds, which reflected the intent of the original Hayabusa to unseat the Honda CBR1100 Super Blackbird as the world’s fastest production motorcycle. Eventually, the Hayabusa managed to surpass the Super Blackbird by at least a full 10 miles per hour (16 km/ h). The media-reported value for the speed agreement in miles per hour was consistently 186 mph, while in kilometers per hour it varied from 299 to 303 km/h, which is typical given unit conversion rounding errors. This figure may also be affected by a number of external factors, as can the power and torque values. In 2000, fears of a European regulatory backlash or import ban led to an informal agreement between the Japanese and European manufacturers to limit the top speed of their motorcycles at an arbitrary limit. The conditions under which this limitation was adopted led to the 1999–2000 Hayabusa’s title remaining, at least technically, unassailable, since no subsequent model could go faster without being tampered with. Thus, after the much anticipated Kawasaki Ninja ZX-12R of 2000 fell 4 mph (6 km/h) short of claiming the title, the Hayabusa secured its place as the fastest standard production bike of the 20th century. Besides its speed, the Hayabusa has been lauded by many reviewers for its all-round performance, in that it does not drastically compromise other qualities like handling, comfort, reliability, noise, fuel economy or price in pursuit of a single function. Jay Koblenz of Motorcycle Consumer News commented, “If you think the ability of a motorcycle to approach 190 mph or reach the quarter-mile in under 10 seconds is at best frivolous and at worst offensive, this still remains a motorcycle worthy of just consideration. The Hayabusa is Speed in all its glory. But Speed is not all the Hayabusa is.” The first generation had a 1299 cc (79.3 cu in) liquid-cooled, inline-4 engine with sixteen valves driven by double-overhead cams. This configuration, technologically unremarkable for that time, delivered a record-setting claimed 173 brake horsepower (129 kW) at the crankshaft by virtue of the largest displacement ever in a sport bike, and a ram air system that forced cool, pressurized air into the cylinders. Combined with sophisticated aerodynamics, this powerful engine pushed the Hayabusa’s top speed far above the Honda CBR1100 Blackbird by a significant leap, contrasting with the incremental gains that preceded the Suzuki hyper sport entry. The 1997 carbureted CBR1100 had previously only inched past the previous top speed record holder, the Kawasaki Ninja ZX-11 of 1990. The Hayabusa engine had an abundance of power throughout its entire rpm band. The 1,299 cc powerplant was the largest and most powerful sport bike engine when introduced in 1999, and remained the largest until Kawasaki’s ZX14 was released. HAYABUSA
