First of the GS Series

The first of the GS Series was the four-cylinder GS750 released alongside the GS400 parallel twin in November 1976. (1977 Model Year). The GS750 engine was essentially patterned off the Kawasaki Z1-900, and became the design basis for all air-cooled Suzuki four-stroke fours until the release of the air-oil cooled GSX-R. The GS750 engine was fitted into a dual cradle frame with telescopic forks, twin rear shocks and a front disc brake. The new GS750 was lauded for its handling at the time of its release, which was a significant improvement over its Japanese contemporaries, the older Honda CB750, the shaft-driven Yamaha XS750, and the more powerful but wayward handling Kawasaki 900. The GS400 was initially bored out to 423 cc (GS425), and subsequently enlarged to power the four-valve GS450, and with an eight-valve TSCC head used on the GSX400. The eight-valve design was later used on the GS500. The GS range was expanded in subsequent model years with a smaller 550cc four-cylinder GS550 and larger GS1000 added in 1977 with the range ultimately including 125cc single cylinder machines the GS125 and larger retro-styled machines such as the GS1200SS.
