The Kawasaki Ninja ZX-14, or ZZR1400 outside North America, is a motorcycle made by Kawasaki that was their most powerful sport bike as of 2007.[1] It was introduced at the 2005 Tokyo Motor Show[2] and released for the 2006 model year as a replacement for the ZX-12R. The ZZR1400 is capable of accelerating from 0–60 mph in 2.5 seconds.[3] The top speed is electronically limited to 186 mph (299 km/h) as a result of an agreement between the major Japanese and European motorcycle manufacturers.

The motorcycle was featured in season 10 of Fifth Gear on October 30, 2006.

Motorcycle USA road tested the bike in its October 10, 2006, issue and posted the following stock results:[4]
60 ft.: 1.713 seconds
330 ft.: 4.349 seconds
1/8 mile: 6.447 seconds, achieving 117.39 mph
1/4 mile: 9.783 seconds, achieving 147.04 mph

Motorrad magazine in Germany achieved the following test results:[5]
Top speed 299 km/h (186 mph)
0–100 km/h 2.9 seconds / 40 m (130 ft)
0–200 km/h 7.6 seconds / 241 m (791 ft)
0–250 km/h 12.5 seconds / 548 m (1,798 ft)
0–280 km/h 18.5 seconds / 991 m (3,251 ft)
The Suzuki Hayabusa (or GSX1300R) is a 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/h).

Hayabusa (隼?) 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.[6][7] In particular, the choice of name was made because the peregrine falcon preys on blackbirds,[8] which reflected the intent of the original Hayabusa to unseat the Honda CBR1100XX Super Blackbird as the world's fastest production motorcycle.[9][10][11] Eventually, the Hayabusa managed to surpass the Super Blackbird by at least a full 10 miles per hour (16 km/h).[4][12]

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,[13] as can the power and torque values.[14]

In 2000, fears of a European regulatory backlash or import ban[15][16][17] led to an informal agreement between the Japanese and European manufacturers to limit the top speed of their motorcycles at an arbitrary limit.[18]

The conditions under which this limitation was adopted led to the 1999–2000[2][3] Hayabusa's title remaining, at least technically, unassailable, since no subsequent model could go faster without being tampered with.[19] Thus, after the much anticipated[20][21][22] 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.[23][24][25] This gives the unrestricted 1999–2000[2][3] models even more cachet with collectors.[26]

Besides its speed, the Hayabusa has been lauded by many reviewers for its all-around 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.[5][27][28] 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."[27]When first shown to the press in 1999, the first Hayabusas made a profound impression.[5] No previous motorcycle has broken the production model top speed record by such a margin, 10 to 14 mph (16 to 23 km/h), depending on which measured speeds the source was relying on for the CBR1100XX and the GSX-1300R.[4][27]

The first generation had a 1,299 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 at speed.[4][27] Combined with sophisticated aerodynamics, this powerful engine pushed the Hayabusa's top speed far above the Honda CBR1100XX Blackbird by a significant leap, contrasting with the incremental gains that preceded the Suzuki hyper sport entry. The 1997 carbureted CBR1100XX had previously only inched past the previous top speed record holder, the Kawasaki Ninja ZX-11 of 1990.[5]

A remarkable feature of the Hayabusa engine was its 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.

The Hayabusa's abundance of power at any engine speed made the Hayabusa easier to ride by giving the rider a greater choice of gear selection for a given speed and stunning acceleration.[27]

The ram air ducts at the front of the drooping, rounded nose squeezed frontal area away from the headlight, and this, along with the need for a narrow frontal area, necessitated a stacked headlight and high beam behind a single lens. Moreover, the need to reduce the extreme drag encountered at high speeds determined the Hayabusa's entire bulbous, and much-criticized, bodywork design. Koblenz remarked, "non-traditional styling generates the main controversy of the Hayabusa."[27] When viewed through the eyes of those who judged its beauty on the basis of its functionality, or given a little time to get used to it, the bike's looks did find admirers.[27][30] The striking two-tone copper/silver paint scheme was similarly loved by some and hated by others, but was successful if the intent of an all-new, flagship product is to make a bold statement.[27] So while it was called ugly by some in the press,[21][26][31] this aerodynamic shape was key to the Hayabusa's ability to reach record-setting speeds.[4]

Reflecting in 2009 on the initial design, the creator of the Hayabusa's look, Suzuki's Koji Yoshirua, said that the intent in 1999 was, "to create a somewhat grotesque design and create a strong initial impact... The mission was to create a total new styling that will not be out of date within few years, and a styling that will be the ‘Face’ of Suzuki." Yoshirua also said that the goal was not to achieve the status of fastest production motorcycle, which in early stages was slated to be only 900 to 1,100 cc (55 to 67 cu in), but that, "as a consequence of, pursuing the best handling, acceleration, safety, power, riding ability, original styling, etc., for the good of the customers, it became the ‘Fastest production motorcycle’ … By doing this, once the model was out in the market and the performance of it have been proven, I thought that people will start to show interest to the weird design, and then the design would be caked in peoples mind.”[32]

The engine used a gear-driven counterbalancer to reduce vibration to the point that the engine could be solidly mounted to the frame, for the purpose of increasing chassis rigidity. Employing a conventional twin beam frame, fully adjustable upside down forks, using specially developed Bridgestone tires, and being relatively light at 473 pounds (215 kg) dry, the Hayabusa's handling was considered excellent for a machine of this class.[4] One reviewer, Koblenz, noted a hesitation perhaps related to poor low-rpm mapping at low speeds, noticeable as a "pause and slight lurch" when rolling on and back off the throttle.[27] Minor low speed FI revisions were addressed[clarification needed] with either a "Yosh Box" or "Teka SFI" FI adjusting tool.[citation needed]
