The Zephyr 550 swingarm is right at 9” wide at the pivot. (I’m almost positive the zrx is 9.25”)
It’s roughly 21” from the swingarm pivot to the rear axle with the eccentric centered.
The rear of the swing arm is 11.5” wide.
You will save yourself an insane amount of work if you get the matching wheel, hub and brake assembly.
You will need an offset front sprocket and a longer chain.
You may need to machine up a new pivot collar and bearing races depending on the size of the 550 pivot bolt. (See the build link in my signature to see how I had to do mine)

Thanks for the info, exactly what I needed. It's going on a 1981 GPZ550.
