@750 R1
what should the tire size be on a 2 inch rim? What’s the stock size on Z1?
the measure I took was from the tire edge at the rim. I am going to look again tomorrow but that would be double the size! I would think the tire would be too big and this is a stock swingarm. 

I run a 120 or 130, depending of profile , on a 2.5 {2 and a half inch} rim. I don't know whats stock on the 900's, I don't have one. The rim size is on the rim, maybe on one of the spokes, but its there, you can't measure rim width with a tire on the rim .

Z1 & Kz 900’s are 2.15” x 18”. Stock calls for 400/18. I’m running a 425/18

 A 120 in metric sizes would do as well..

good morning,
thanks guys, I am more familiar with automotive sizes for tires. The rear tire on the bike now is size 110/90/18. How is that in comparison to what the standard size should be? I see 18 being the size of the tire/rim, but are the other numbers metric?

110 (mm) is how wide the tyre is.
90 (mm)  stands for 90% aspect ratio, as in the profile height of the tyre is 90% of how wide it is.
18 (inches) is as you said, the rim size.

Thanks Mikaw, KZ, 750. Y'all are a wealth of knowledge. I am getting this bike back on the road, it sat for 18 years inside basement storage so its in excellent condition.. It turns over and fires but need to clean the carbs and put a tag on it. It wants to go. I need new tires since the existing ones are old. I will keep searching for some period correct rims and then sell the mags.

They are getting really hard to find unless your will to pay big bucks. $300 seams like the going price, with some asking upwards of $700-800. You can still find hubs and spokes reasonable. DID rims are becoming an acceptable swap in.
