Okay, let's go up in displacement
The year in question would have to be 1981-82, because the tail section on the GPZ's was different in 1983. Am I closer?
Sorry for the delay answering this trivia, I had a problem with my connection here in Greece.

The year is 1981 and the common characteristic is that they are the top of the range (4 cyl) bikes of these manufacturers for the year.
