In the US at least, the first one is an '82 GS1100E. like Wykydron said. I had an '83, looked the same except red, great bike. There was also an '83 model with a mini-fairing but the same other bodywork, then the Katana like the one Scummy posted. Can't remember the designators. In '84 they went to the GS1150.
The second one is older at the tank and headlight but looks like it has the seat from the '82.
