Yea, the designation was changed in 1976. 1973-1975 900 was called the Z1, the 1976 was called the KZ900. Some KZ900s were also made as 1977 model year. That was the end of the Z1/KZ900. 1977 was the release of the KZ1000. So if you have a 1979 900 it is neither a Z1 or a KZ900 because 1979 there was no 900 models from Kawasaki.
321,000 miles on KZ's that I can remember. Not going to see any more.
