On a 5.5" rim you can run either a 170 or 180.
No bigger or smaller. or you will ruin the handling due to profile distortion or tyre flex.
There's very little difference in different makers mounted tyre widths to cause any issues but go for 170 if you want plenty of leeway.
You should use a 5/8"ths offset front sprocket and set the rear sprocket mount face 110mm from the center line for correct chain alignment.
With the wheel true central the chain run will just slip past the tyre and frame with a couple of mm clearance.

Zed1015,

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.

Im in love with those wheels though..cant stop imagining them on a GPZ1100. What is the axle diam front and rear in mm if you don't mind me asking?


Both are 24.90mm ish. I’m assuming a25 mm axle

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.

Great looking bikes. I’ll be leaning one you if you don’t mind. I thought I was the crazy on involved in Two builds at one time. But if your committed to the builds and time isn’t a factor lord willing then I’m buying parts as good deals come along.

Zed’s pictures inspired me to do a quick mock up to help keep the juices flowing.

Zed - what conventional forks did you use on the Z1R?

They are Yamaha FJR1300 held in with two bottom yokes and home made risers.

Did a little research today at lunch. Found out the 1999-2007 Hayabusa has the same spline size as the KZ for the counter sprocket. I found a 5/8 x 18 x530 front sprocket. They have a 17t also if a want a little more off the line. Then I contacted Vortex Racing and they make a 530 sprocket the will bolt up to the GT1000 Ducati cush drive. available in 34-54 tooth. At least the drive chain is covered.

You may have to go with an aftermarket clutch casing /actuator as often an offset sprocket wont fit under a standard cover, i might be wrong but i had issues with mine and had to upgrade to a PMFR clutch release kit which gave me the space.

I also went with the PMC easy clutch ( pics below) but I may be upgrading to a hydraulic clutch system yet .
