GPZ900 Swingarm swap to ZZR1100c for wider tyre

Anyone knows the widest tyre size I can fit into zzr1100 swingarm on GPZ900?

I have a ZX1100C (ZZR1100C elsewhere) that has a 200/17 on it, on a 5.5" rim. 180 is plenty big enough for the 11.

Probably 180, but the limit will be chain to frame clearance. Check that out first (and allow 3-4mm for sideways movement of the chain in each direction) before you go swapping arms.

Thanks guys, just trying to find out which swingarem i can swap to have a fat tyre on my gpz900. I know zzr1100c is somehow compatible but I was trying to find another more recent model arm option that can take fatter than 180 and can be fitted by some machine work. Cheers
