The 1982 Katana styled GSX400E was offered in the Katana silver or red. Appart from the "sweet Katana" estetics, there were some technical changes:
1) New ignition fully electronic (previous one had a mechanical centrifugal advance system) and ignition advance goes to 30º from previous 20º
2) Carburation tuned to adapt it to exhaust modifications
3) Electrical fuel tank gauge
4) New frame, special mention to rear swinging arm getting 40 mm longer
5) Steering column strongly triangled, turning on conical bearings
6) Anti-dive front fork
7) Engine cover screws changed from cross to hexicon head

The changes in the motor and cycle parts make it a more consistent and brilliant bike.

Originally the GSX400E was offered with a single disk front brake and a anti-dive system fitted on the left side only. Because of the construction, according to some owners, the front fork felt strange at full braking from high speed. The single disk was good enough for stopping the bike but a version with double-disk and anti-dive system for both sides was available for the GSX400E from 1982 year's model in order to get rid of the odd behavior.

1983 Suzuki year code: D, GSX400ED, GSX400E-5
In 1983 the GSX400E got new type of cast wheels and a black-coated engine. Probably even the instrument panel got a new design. The paint scheme was new but mechanically the model remained unchanged.

As earlier, a model version called GSX400S with a small fairing was offered for those who wanted some protection against the wind.
