A Legendary is Born

The illustrious history of the begins with Suzuki’s for first-generation GSX-R750 in March Born on the circuit, returning to the The GSX-R750 was designed to challenge championships while fulfilling the aspirations of non-professional riders.

Fujiwara, who was in charge of the basic of this first model, recalls the excitement of his team at the of the project. This pure model was our first 750cc featuring an aluminum frame of light weight and superb rigidity. We had no real competitors in the other than factory machines.

The oil-cooled 4-…, engine of the GSX-R750 delivered than 100PS — far power than any previous motorcycle. The exceptionally low dry weight of (395 lbs.) was equivalent to of a 400cc-class model. Isamu engineer of engine design We knew that reaching our of the world’s best power-to-weight required to realize overpowering would be an enormous challenge.

The was a natural sensation among enthusiasts and the press at a time the capacity limit for Formula One and racing had just been from 1,000cc to 750cc. new 750 performed admirably in the AMA Superbike and FIM World Endurance Championship and became the racebike of choice private riders worldwide, to durability and affordability.

When American rider Schwantz rode the GSX-R750 second place at the 1986 AMA 200, his name became with the machine. Schwantz’s riding style on the GSX-R750 an incredible man-machine interface quickly engendered a legend. in AMA Championship and the Le Mans and Bol d’Or endurance events soon to anchor the beginning of GSX-R750’s history.

The Champion Grows Up

several model changes in the years to raise performance and in the lead, Suzuki changed the of the 1992 GSX-R750 from to liquid-cooled and adopted a more frame with a large, cross-section. Hiroshi Iio, engineer of the GSX-R series, a secret episode.

We development members shared a clear to realize higher performance, weight and more compactness facilitated agreement on technical Iio recollects, But aesthetic matters as engine’s appearance did cause arguments. For example, we asked Air Self-Defense Force to show us aircraft power units as for the fin shape on our ’92 GSX-R750.

For the model, engine designer Nishikawa strove to figure out the desirable characteristics for a new-generation I frequently visited major championship circuits to collect information, he says. The answer was an new engine with three-piece and a side camchain.

Combined the all-new twin-spar frame by the Grand Prix race this version achieved weight reduction from its

The highly evolved GSX-R750 the catch phrase ‘The advanced GSX-R ever’ in That model’s totally engine featured a new electronic injection system with throttle valves — a controlled throttle valve and an controlled valve — enabled optimal fuel for greater torque and power, as as higher combustion efficiency lower emissions. The new main was lighter, with a longer arm than the previous model.

Together, the innovations offered GSX-R750 riders overpowering approaching that of a one-liter

Yukihiro Takasaki has been to development of the electronic fuel-injection in all GSX-R series models 1999. As a private race mechanic I had a close contact GSX-R750 when I joined two decades ago, says so I was eager to take charge of development. Our team was thrilled to a new fuel-injection control system helped to exceed performance of competitors.

I’m happy to say Suzuki’s fuel-injection technologies are leading the industry today.

The Mission of Excellence Continues

The has steadily expanded the lineup for the 20 years. In the year following the debut, Suzuki launched GSX-R with a 1,052cc boasting a maximum of 130PS at with a dry weight of only (434 lbs.). Like the the GSX-R1100 ruled the racetracks and the until 1998.

For riders who the GSX-R experience in a middleweight Suzuki introduced the GSX-R600 in Kunio Arase, project for this new member of the GSX-R says he started development a mission: The mission shared by engineer for succeeding models of the GSX-R line has been to the performance of any existing model in its

We determined to achieve the fastest top and starting acceleration, yet the production had to be transformable to a winning circuit with minimal modification. the first GSX-R600 realized a top faster than that of the two years earlier, taking the Supersport Championship for two consecutive

In 2001 the youngest member of the was born, the GSX-R1000. Thrilling all and garnering one racetrack victory another, the 1000 has become the of the GSX-R line with its potential. This year, the of the GSX-R1000 is going to the market an even bigger displacement to deliver more power, and acceleration, as well as a totally body with less and higher aerodynamics.

Hiroshi the engine designer of early-1990s is now working as the chief engineer on the GSX-R1000. Every GSX-R in has been created to become the and strongest sportbike of its time, he Of course, the latest GSX-R1000 the original GSX-R concept to an higher level. The 1000 is the nimble, powerful and lightweight model yet, as well as an rider-friendly bike.

I wanted to a charming machine that every rider exceptional joy of The chief styling designer and I to create functional yet attractive worthy of a new-generation sportbike.

was a year-long celebration of the 20th of Suzuki Motorcycle’s legendary GSX-R, which has dominated racing circuits since a debut in 1985. The company has evolved the series from the GSX-R750, to maintain a consistently expression of Suzuki’s racing To deliver the pure excitement of performance to more riders, has also expanded the series larger- and smaller-displacement engine

The 20th anniversary of the glorious in 2005 is a time for Suzuki to while mapping out even advances of Suzuki’s superb motorcycles. The legend continues.

The 1985 Suzuki weighed in at a mere 179kg. on an aluminum double-cradle frame the MR-ALBOX, the 4-cylinder DOHC used the Suzuki Advanced System (SACS), cooled by pumping in oil. With by companies such as Yoshimura, the turned in spectacular performances at domestic and overseas circuits.

The model featured a lightweight alloy frame, flatslide twin discs with calipers and 18 inch tires front and rear. An oil-cooled was made to save weight as with the heavier water-cooled of the time.

With the introduction of the Suzuki RG250 Gamma, was the first manufacturer to bring a racer replica using technology to the public. With the Gamma a success, the next was to build a 4-… 400cc for the Japanese home market and a later a 750cc machine, the Suzuki’s racing experiences in the Endurance, AMA Superbike and Championship.

At the IFMA Cologne Show in Germany the GSX-R750 was introduced; a legal bike with a to compete in the various Worldwide It would go on sale in March

In 1985 Suzuki GSX-R750 race-bred technology and performance at an price. The design philosophy mainly on weight reduction. went counter to the conventional design by developing a computer packed with SACS Advanced Cooling System) the cylinder head and the pistons are oil via the engine oil injection, achieving efficiency as good as water-cooling 10% weight decrease.

The GSX-R750 also featured (Direct Air Intake System), (Twin Swirl Combustion cylinder head, flat carburetors, six-speed gearbox and clutch. The chassis offered extrusion molded aluminum box piping and cold-cast aluminum components, MR-ALBOX frame weighted 8,1 kg less than of the conventional steel frames).

and other weight reduction gave the bike a low dry weight of 179 kg, 20% than the competing 750s, a superior power-to-weight ratio for easier power control and handling. Completing the GSX-R750 was the endurance racer theme: headlights on the aerodynamics full and 18-inch tyres both and rear.
