As others have provided, 1981 (I think) Suzuki GS1100 is about the only one I've heard of where minimal mos are required...

From others, maybe a spacer or modified bearing but pretty much a direct fit...

You know it's weird, I don't see where more Honda or Yamaha conversion parts are used.... Interesting...

old man i right.the suzuki gs1100 arm is the most common.that is what i use.they fit with no mods just a small spacer on each side of the pivot shaft.this will keep the dual shock setup and that is what i prefer on a old kz. here is a pic of the z i'm building now with a gs arm.this will also alow you to go to rear disc.these arm come up on ebay all the time and normaly sell for $75-125.

2003/2004 ZX6RR J link mono....
Requires a considerable amount of modification..... Not only for swing arm mounting but for battery/electrical as well....

And before getting even starting, definitely think about offset & rear sprockets, chain path, rim/tire etc... ;)

I believe you can fit a 180 tire in the gs arm. I have a 140 on mine and have plenty of room for a bigger tire. Next year I'm going up to a 170.

With a wheel that big, do you have to use offset sprockets? I have a 140 on mine and the chain comes pretty close to the tire.
