7mm front disc calipers??

What bikes came with a 7mm front disc?

I am in the process of swapping my kz650 mag wheels to spokes and happened upon a '76 KZ900 front wheel with the 6 bolt 7mm thick rotor. I need to source a caliper to fit that size rotor. Were the early kz650's fitted with 7mm thick discs?

Any info greatly appreciated.

Found a way to search in another post from JMKZHI

Well, you can cross-reference individual parts at Kawasaki.com. I find it easiest to search by year only.

Kawasaki.com (USA) -->> Owner Info -->> Parts diagrams -->> Search-by-Model-Info -> click continue -->> choose a year only then click continue -->> pick a bike from the list. Once into the diagrams, click stuff. Most diagram reference numbers are clickable which speeds up finding the full part number below. Clicking the part number opens a new window - click the yellow/black ? for the cross-reference... another new window opens w a list of bikes using that part. Click the red/white S for the superseded part number info.

If your computer has a pop-up blocker, the diagrams may not work. You'll have to turn off the blocker or otherwise allow popups from the Kaw site.
