It was a beautiful bike that had led a very cared for life. I had so little experience when i bought it that i assumed everyone took care of their KZ750 twins in the same fashion. I was wrong. With hindsight I do now feel a bit bad for chopping such a pristine machine but I lavished so much care on the build that i hope that the heart of the machine is still happy on some level.
As far as model ID goes. We never got the K in Australia. Am I correct in thinking that the S is essentially the K but with chain drive?
