This motorcycle also showed the great advantages of modular engineering, in which the 600 could successfully be based on the 70. Page 3: Styling has always been an important part of the GSX-R design—the original was based so closely on the endurance-race-winning GS1000R that it could almost be mistaken for it—but with the latest generation of GSX-R, it has become nearly an obsession. Numerous styling designs have been tried, in both illustrations and mockups, to be sure the latest version is both handsome and true to the GSX-R’s heritage. Page 4: It was the push for more horsepower that drove the engineers to liquid cooling. With that decision made, they could reduce the size of the cylinder block and head and incorporate the direct-action valvetrain they had wanted to use two years before—and still retain a fair portion of the previous engine’s bottom end. Page 6: The GSX-R is tested in the tunnel with a rider aboard to determine the overall shapes. Page 8: New ideas, new directions but a continuing clarity of focus allowed the initial designs for the 004 GSX- R600 and GSX-R70 to reach for a fresh, angular look that set the model apart from the more rounded, organic styling of the previous generation. Many of the ideas in this illustration made production, including the angular headlight and ram-air treatment, while others did not, namely the extended side panel and rounded tail section.

Schwantz continues to work has the ground-breaking race-replica sportbike to the incredible machine it continues to be today. with Suzuki as an advisor There is no doubt in my mind that the Suzuki GSX-R was well ahead of its time. I remember to the Yoshimura Suzuki team and through the Kevin hearing a lot about the bike and then seeing photos in early 1985, thinking, “Wow, this is an amazing- Schwantz Suzuki School. looking street bike.” I could tell that it would translate well into a race bike, but I also thought that it BelOw: A much younger— would be a big change from the bike I had been riding for Yoshimura in 1985, the GS700E.

The were less developed than they are now, even a bit crude. At the time, I didn’t think so. When I came 1986 racing season was Yoshimura’s first with the into the Yoshimura team, it all seemed incredibly exciting and I was just happy to be there, working GSX-R, but this “building year” paid off well for 1987, for a well-run team that had good equipment. My goals and strategy were pretty simple: take it day when Schwantz scored five by day and win races. wins aboard the Yoshimura- prepped GSX-R. I always got along with the GS700E. I’d come from motocross and dirt track, and so I liked the big handlebar. The bike, to me, was an absolute hoot to ride. It would do what I wanted it to do, went where I wanted it to go. I wouldn’t say finesse was a big part of my style then, but my style seemed to work well on the GS. We won the second race of 1985 at Willow Springs and picked up two more wins later in the year. I think the fact that Yoshimura had a year of development on the 750cc bike before I got there really helped. In 1985, I got to ride the GSX-R750 for the first time in a 200-kilometer race with Graeme Crosby as preparation for the Suzuka 8 Hours. I was imme- diately impressed with the bike’s performance, even if it was a big change for me going to clip-on handlebars from big, dirt bike-style handlebars. 10 11 ChApter 3 OPPOSiTe: Although the engine moved to a short- RaciNG DRIVES stroke design and received a significantly altered cylinder head, it was DEVELOPMENT—AgaiN fundamentally the same.

Kevin Schwantz’s first season aboard the GSX-R, 1986, netted a single win in AMA Superbike. Honda’s first aluminum-frame VFR750 arrived that year, and Fred Merkel put the company’s substantial (some said “enormous”) race budget to good use, winning his third title in a row by ’86. The next year Schwantz took five wins and came home second in the championship. But it wasn’t enough for Suzuki, whose corporate pride was hanging way over the line. The GSX-R was conceived to win, and win it would. In the U.S. and abroad, the competition had stepped up to Suzuki’s challenge with the GSX-R, but plans were in place to advance the state of the art. The result, which debuted as the 1988 GSX- R750J model, represented a wholesale revision of the bike, with every part of its design—engine, frame, suspension, bodywork—dramatically revised.
