During the summer of 1981, Suzuki released the production Katana with almost exactly the same body styling seen at the Cologne show, with subtle improvements in the engine and running gear. The body styling is from the genius of Mr. Hans A. Muth of West Germany, who spent much time ensuring driver comfort in his design, and which proved out in many wind tunnel tests. The entire styling was derived from research on the best drivers position, and the rearward placed backsteps and unique tank styling were not done just for the pleasing jet age appearance.

Large capacity fuel tank and small fairing were blended together for the best airflow around the rider and the bike. Although the bike is most noticeable for its styling, every part in it is quality. Engine is an air-cooled, parallel 4 of 1075cc, using 16 valves. With unique Suzuki TSCC (Twin Swirl Combustion Chamber) in the engine, it puts out 111 hp. This tremendous power transmits into a road speed of 230 k/ph and its unique body styling keeps it stable even at these high speeds. Suzuki is shipping a 1000cc Katana GSX1000S to the American market, and also a 750cc version to the European market as well. Requests form Japanese enthusiasts prompted Suzuki to also market a 750cc Katana GSX750S to their market.
