Suzuki 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 , 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 CBR1100XX Super Blackbird as the world's fastest production motorcycle. Eventually, the Hayabusa managed to surpass the Super Blackbird by at least a full . ==First generation (1999–2007)==

When first shown to the press in 1999, the first Hayabusas made a profound impression. No previous motorcycle has broken the production model top speed record by such a margin, , depending on which measured speeds the source was relying on for the CBR1100XX and the GSX-1300R. The striking two-tone brown/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. this aerodynamic shape was key to the Hayabusa's ability to reach record-setting speeds. 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 dry, the Hayabusa's handling was considered excellent for a machine of this class. The informal agreement went fully into effect for the 2001 model year. Performance and measurements ==Second generation (2008–2020)==

Suzuki lightly revised the GSX1300R for the 2008 model year, with a minor restyling of the bodywork, and fine-tuning of the engine's head, pistons and exhaust. Though the engine changes were relatively limited, they still yielded a large horsepower increase, and brought the bike into compliance with new noise and emissions requirements. Planning In 2004, market researchers from the US and Japan began working to identify which elements of the Hayabusa design had attracted so many buyers, discovering that, in spite of having its looks sometimes disparaged in print, customers were much enamored with the old Hayabusa. A redesign meant to strengthen the bike's appearance without departing much from the original found approval with dealers and focus groups. Underneath the skin, Suzuki decided to save considerable development cost by keeping major portions of the frame and engine unchanged. The target was to produce more than at the crankshaft, and they delivered , an 11 or 12 percent increase over the previous output. When the new Hayabusa was released, independent tests bore this out, with @ 10,100 rpm measured at the rear wheel. Technical revisions Engine changes consisted of an increase in stroke by 2 mm, enlarging displacement to . The compression ratio was boosted from 11:1 to 12.5:1 and the cylinder head was made more compact and was given lighter titanium valves, saving and on each intake and exhaust valve, respectively. The valves were driven by a chain with a new hydraulic tensioner. The pistons were made lighter by There were no changes through the 2011 model year except for new colors. Alongside the second generation Hayabusa, Suzuki developed the new B-King, a naked bike in the streetfighter mold, using the same engine but with a different intake and exhaust. Performance and measurements , 2008 ==Third generation (2022)==

The third-generation Hayabusa was announced on February 5, 2021. Cycle World and Motorcyclist magazines referred to the third generation 2022 model year Hayabusa as GSX1300RR rather than GSX1300R, with no mention of what that might signify. ==Sales==

Typically, a new sportbike model sells well in its first year, and then sees its numbers decline every year as it grows older. The Hayabusa reversed this pattern, selling in greater numbers every year from the 1999 launch through the 2008 revision. In the United States in each of the years 2005 and 2006, over 10,000 units were sold. It was predicted that the gentlemen's agreement speed cap would hurt sales, because buyers would not want a bike that was hobbled with a speed limiter, even riders who would never approach the hypothetical maximum. However, sales in the United States increased year after year between its release in 1999 and 2006, rising from just a few thousand units in 1999 to over 10,000 in 2006. ==Competitive motorsports==

Many riders have found that the Hayabusa lends itself well to any number of functional purposes, including competitive motorsports. The Hayabusa has been used in sanctioned closed course road racing, drag racing, and top speed competition. Top speeds of over 270 horsepower, and performances in the standing quarter mile as quick as 6.9 seconds and as fast as 209.14 On July 17, 2011, riding a highly modified turbocharged Suzuki Hayabusa, Bill Warner set a new world motorcycle land speed record of from a standing start to 1.5 miles at the Loring Timing Association's Land Speed Race, held at the Loring Commerce Centre (the former Loring Air Force Base) in Limestone, Maine. ==Custom versions==

2008 The Hayabusa has been one of the top choices for streetbike customization, perhaps even the most popular customized sportbike. One reason may be the unique, instantly recognizable bodywork. Bikes are usually built around a theme, are common. {{multiple image | direction = horizontal | align = left | image1 = Custom Hayabusa blue mohawk helmet.jpg | width1 = 167 | alt1 = An motorcycle with fully enclosed bodywork painted in iridescent blue with flames, and a helmet painted in the same color scheme, with a matching blue fur crest on the helmet. | caption1 = A blue customized Hayabusa | image2 = Big Tigger's Hayabusa? 2.jpg | width2 = 154 | alt2 = A motorcycle with fully enclosed bodywork painted with a complex black, gray and white pattern, and crome plating on many parts of the bike, and an extended length rear swingarm and an extraordinarily wide rear wheel, indoors with special chrome wheels on display in the background. | caption2 = Notable on this example are an extended single-sided swingarm and the appropriation of the Decepticon logo. | image3 = Hayabusa Gulf 2.jpg | width3 = 172 | alt3 = A pale blue motorcycle with a prominent Gulf Oil logo and a unique front fender that encloses almost the entire front wheel on asphalt with a sign in the background that says Young Choppers and Hot Rods. | caption3 = A more retro theme with an enclosing front wheel fender, Gulf Racing livery, and a parody of the Goodyear logo. | image4 = Custom Hayabusa Atlanta 2008.jpg | width4 = 166 | alt4 = A motorcycle indoors on display with other bikes, with gray metal-flake, painted fully enclosed bodywork, and the logo of Superman painted on the front and side. | caption4 = The Superman-themed "Kong" glitters at a show. | image5 = | width5 = 167 | caption5 = A Hayabusa fitted with an exhaust gas turbocharger for increased engine power ==Police use==

In 2006 the Oklahoma Highway Patrol (OHP) converted a seized Hayabusa into a pursuit vehicle, setting up the bike with equipment including a radar unit, police lights, and siren, and painting it in official colors and insignia. Impressed with the positive response from the public and the motorcycling community, the OHP purchased two more Hayabusas, to supplement their main fleet of Harley-Davidson police motorcycles. While they are used for patrol, the primary function of the Hayabusas is public relations and community outreach, due to the kind of attention the exotic bikes attract. According to the OHP, "There are clear lines dividing sportbike and cruiser motorcycle riders. We feel the sportbike community has not been given the proper amount of attention and focus in the area of community involvement and rider safety education." In 2009, Humberside Police in the United Kingdom put an undercover Hayabusa on the road, equipped with speed detection equipment and a video camera, as part of Operation Achilles, which aimed to catch speeding motorists and motorcyclists. In the town of Arecibo, Puerto Rico, the Puerto Rico Police operates a "superbike unit" composed entirely of seized Hayabusas that have been outfitted with lights, sirens, police livery and radar equipment for speed enforcement duty in the northern region of Puerto Rico. In late 2021, the Arecibo municipal government announced the acquisition of seized vehicles for the Arecibo Municipal Police in conjunction with the Puerto Rico Department of Justice, among them a Hayabusa. Like the Hayabusas owned by the PRPD, this Hayabusa has been outfitted with lights, sirens and police livery to be used as a patrol vehicle in Villas del Capitán Correa, located at the northern part of the town. ==Other uses of the Hayabusa engine==

The high-powered lightweight engine in the Hayabusa lends itself to non-motorcycle applications. The Westfield Megabusa is an English sports car, based on the Lotus Seven, which uses the Hayabusa engine. Suzuki was the first to put the motorcycle's engine in a car, with two concept cars in 2001, the Suzuki GSX-R/4 roadster and the Formula Hayabusa, an open wheel race car "designed for a new Japanese one-make competition series." Mike Akatiff's 2004 land speed record attempt TOP 1 Ack Attack streamliner used twin Hayabusa engines in an attempt to exceed at Bonneville Salt Flats. In 2006 and again in 2008 Akatiff's Ack Attack, ridden by Rocky Robinson, succeeded, first going in 2006, only to be surpassed two days later, then returning in 2008 to set another new record of . That record stood until 24 September 2009, when it was broken by Chris Carr with a speed of . Radical Sportscars use the Hayabusa engine in stock form in their SR1 entry level race car and in a modified form up to 1.6L in their SR3 and PR6 cars. They also designed a V8 engine based on the inline-four Hayabusa engine using dual Hayabusa cylinder heads mated to a custom bottom end, known as the Powertec RPA V8 engine to power their SR8 car. The sports car set the record for the fastest production car at Nürburgring. The Hyper Racer X1, designed by Jon and Dean Crooke, is fitted with a standard Gen2 Hayabusa engine. With ground effects and a weight of only 400 kg the Hyper Racer X1 holds outright and class lap records. John Hartley, president of a custom printing machine manufacturer, created a 75° V8 engine producing and torque that weighs , based on the Hayabusa engine, initially intended to power his Caterham Seven sports car. One of Hartley's engines has also been put in an Ariel Atom open wheel roadster. SmartBUSA sells a conversion kit to install Hayabusa engines in Smart Cars. The Vitabusa is a race car original designed by West Racing Cars, appeared in PIC, Taiwan. A project to build a modern replica of the 1939 Bugatti Model 100 air racer used twin Suzuki Hayabusa engines in place of the original design's pair of supercharged straight-eight engine. Hayabusa engines have been used in sandrails, lightweight space frame off-road vehicles for sand dune racing and recreation. While many sandrails used in events like the Abu Dhabi Desert Challenge have relied on car V8 engines, lighter motorcycle engine like the Hayabusa 1300 gives the sand car advantages in acceleration and maneuverability. Introducing the Suzuki Vision Gran Turismo: the 'Hayabusa' Engine and Electrification Technology in an AWD Super Sport. The base chassis is a front-engine, rear-wheel drive layout with a front mid-mounted engine, but adds electrification technology to combine the engine with electric motors, to complete the all-wheel drive system. The front mid-mounted engine is a 1340 cc inline 4 cylinder used on Suzuki's ‘Hayabusa’ flagship sports bike. Furthermore, a total of three motors, two for the front drive and one for the rear drive, have been added. The combined total output of the system is 318 kW (432 PS) / 9700 rpm, with a maximum torque of 610 Nm (62 kgfm). The Hayabusa engine has also proven a popular choice for use in single seaters within the British Hillclimb Championship, due to the integrated gearbox and light weight packaging. They are used in various configurations, ranging from stock sized engines, enlarged naturally aspirated engines, supercharged and turbocharger conversions. It is also not uncommon to see these engines run on methanol fuel, since it allows the naturally aspirated engines to run higher compression ratios and the force induction engines to not use an intercooler, thus further saving weight in the car. One of the more successful Hayabusa powered single seaters is the GWR Raptor, designed by Graeme Wight Jr. These cars have produced up to 480 hp while weighing less than 400 kg with a driver aboard and prove competitive against the larger, heavier and more powerful V8 cars. ==Notes==
