Re:
Thank you very much for your kind words.
In a extraordinary coincidence, I looked into getting those very two bikes when I had the idea of riding a motorbike again. The z650 is a beautiful machine, and I remember being envious of a friend who bought one in 1978, when I myself bought a new Honda CB550 Four K3. When I did my refresher course also went to a local Kawasaki dealer and sat on a z900RS. They offered a test ride, but I though even then it would be a little too big and heavy for me.
