The Kawasaki KX 125 was first marketed in the United States in 1980. It was sold on the Asian markets like Japan in 1979.
It's 42cm (16.5")

On the head stock behind the headlight will be stamped into the frame.
According to the Clymers manual it should be 0.028 - 0.031 Hope this helps.
No, the 125 swing is slimmer and has smaller axle and bearing and different eye positions for the shocks.
All you can adjust is the preload. You need a spanner wrench. http://www.xs650.com/forum/
