Suzuki presented a whole new lineup in 1981 with Katana styled bikes where fuel tank, seat, side covers and tail were blended together, in some cases with a cockpit fairing. Initially there were three of them, GSX1100S, GS550M and GS650G. Later came the GSX1000S Katana and the GSX400F, a model with a four-cylinder, 16-valve engine. The GSX400F (internal code GS400XF) was available for two years. In 1983 the model was replaced with the liquid-cooled GSX400FW. Needs maintenance of its 16 valve head and carbs to avoid burnt valves. The air-cooled models (with smaller sump that the FW models) had some problems with the engine overheating and some examples had even problems with the charging system. Burned alternators are quite usual for all the other early GSX models as well and there should be better replacement alternators available for all GSX models. Here's the GSX400F Katan brochure page.

In 1982, the GSX400FZ (GSX400F-II in Japan) was released with new graphics and a new anti-dive front. But for the Japanese home market there was also the GSX400FS Impulse, with an oil-cooler and additional three horsepower. The Impulse had a black-coated engine and gold painted wheels. Although the GSX400F model name disappeared from the catalogues after 1982 and the water-cooled GSX400FW took over, the model suddenly re-appeared in 1989 with an engine from the GSX-R400R and the frame and the fairing from the GSX600F.

Although the GSX400F model name disappeared after 1982 and the water-cooled GSX400FW took over, the model unexpectedly re-appeared in 1988 (with an internal code GK74A). With an engine from the GSX-R400R and the frame and the fairing from the GSX600F, Suzuki tried to introduce a unexpensive mid-range tourer for the Japanese home market. Although the model was large and comfortable for being a 600cc motorcycle, the engine was too small and the model wasn't popular enough. The model was available only in 1988-1989.

GSX400F 1988 GK74A Overall Length: 2 110 mm (83.1 in) Overall Width: 700 mm (27.6 in) Overall Height: 1 145 mm (45.1 in) Wheelbase: 1430 mm (56.3 in) Dry Weight: 183 kg (403 lbs) Engine type: Water-cooled 398 cc inline-4, DOHC, 16 valves. 59 hp/ 12.000 rpm, 3,9 kg-m/ 10.000 rpm.
