Help! Unknown Tripple Tree?

Hello, got an unknow Kawasaki tripple tree set. 35 mm tubes. Same distance apart as a Z1. For hydraulic disc brake. Has a hole mount for a stabilizer!
The handle bar clamps are on a rubber mounted stud.
It has been in my garage for 20 years.
It has a stainless cover that slides over the key hole for the stem lock. It has a lock # of 279.
Any help?
Here is a picture.
Thanks,

i think 750 twins had the rubber bar mounts on top tree;) maybe ask steell if it looks right

If they are 35mm, here are some of the Kawasaki models with 35mm forks. One simple way of narrowing it down is to look for 35mm fork seals.

S1 KH250 S2 S3 KH400 H1/H1A/H1C F4 F8 F11 F5 F9 F12 KX450 ZX550 (84-85) KE175 (80-83)

Hi Jeff, How is the business going?
I sold the black 73 Z1 to a guy in Lewiston. He might have talked to you already. He loves the bike!

I will do some searching to find these trees.
I will paint them after I glass bead them.
Going to the "bay".

Nope, they are not off any 750 twin that I know of, the 750's are 36 mm (at least through 1980) and don't have those round mounting holes on the fork clamps. Lot's of other differences as well.

z1r?
