I found out exactly what you said when I talked to Les, he mentioned that even tire sized at lets say a 180 will actually be very different widths. Unless i would buy 10 tires and measure How would I find out which brand might be narrower if that's what I need.

Other than asking folks to measure what they have, I don't know. If you have a dealer near by that stocks several brands, you could probably drop by with a tape measure,and get an idea of unmounted widths of whatever they stock.

Thanks Tex. I missed my opportunity. The two dealerships near me both said they had hundreds of tires about a week and a half ago. The tire companies weren't picking up due to covid. Dang, but I found a 180/55/17 that I got free and mounted. It fits in the GS1100e SA. Now I need to mount the swing are and see if the chain will clear it... I will check with the dealers in about a week and see what else I can find. One dealer had 2 180's but different brands and there was a 1/2 overall difference. I picked the narrower of the two.

Any news about chain clearance?

Thant you, reassuring to hear you mention a 5/8 inch offset counter sprocket also, that’s also what Les recommend. Without having a tire on the rim I put it briefly into the GS 1100e swing arm and as long as the tire is not much wider than the rim this looks like it will be a fairly easy conversion. I will need to find bearings that match the Ducati rims bearing boss OD with the 20 mm axle that the GS1100e swing arm uses.

I've done tons of these Z's with 17" wheels and have five of my own done the same so i know what works and the details and measurements are pretty much etched on my brain.
These are the latest two i'm slowly working on.
The 1000A uses ZX7R wheels with 5.5" rear and the Z1R has ZX12R wheels with a 6" rear and 200 tyre.
The Z1R needed the frame scalloping for the chain run and would have needed a 7/8" offset but i extended the gearbox output shaft instead so i can use a plain stock sprocket and save cash when it's time to replace them.

Zed, do you have a build thread for the Z1R ?

Going to be spring time before I get around to this again. Elbows deep in the ‘76 Kz900 project.

Yes! I have one over on the Z1 Owners GB Forum.
It's a joint build with both bikes on the go .

Thanks Zed....

Thanks for posting that Zed. You have some great examples over there on modifying the pivot point without heavy machinery.
