The first major changes to the motorcycle took place in 1986 (the '' GK71F generation). The model received a new look with a rectangular headlight, a new exhaust system, new brake discs and a new generation of aluminum frame. The wheelbase is shorter and the power-to-weight ratio has been increased to 0.39 hp. per 1 kg of weight. The engine receives a proprietary cooling system using a combination of liquid, air and oil (SATCS - Suzuki advanced three-way cooling system).

In 1987, the generation remained the same - GK71F. However, the model changed again. The Suzuki GSX-R 400 has returned to double round headlights (the previous rectangular design was in low demand). The exhaust system, calipers and wheel dimensions have also been updated. There was a "track" modification SP (Sports Production), which was distinguished by a sticker on the plastic, the gear ratio in the gearbox, additional suspension rebound adjustment and a rear shock absorber with a remote reservoir.

The year 1988 was marked by another serious restyling of the Suzuki GSX-R400 (generation GK73A). The model features a more modern design, a new exhaust system, a new generation of aluminum frame, new 4-piston Tokico calipers, a new curved radiator and new carburettors. In 1989, the letter R 'is added to the model name - Suzuki GSX-R400R.

In 1990, the model undergoes the last major restyling (generation GK76A). New look, new headlight design, inverted fork, new aluminum frame, new 4-in-1 exhaust.

In 1993, due to the update of Japanese legislation, the maximum power of the Suzuki GSX-R400 was reduced to 53 hp, and 1995 was the last year of production of the model.

The Suzuki GSX-R400 engine was subsequently installed on models such as Suzuki GSF400 Bandit and Suzuki RF400.
