The ZZR1200 forks just slide into the ZX11 tripple clamps, no mods needed. I highly recommend the swap, just make sure you change seals and fluid. And if you're on the heavy side like me at 250lbs, see about some slightly stiffer springs.

The ZX11 calipers do not fit because the bolt holes differ, but from what I understand GSXR1000 six piston calipers will bolt on without mods.

I have no experience with the LSL bars, although others on this board do. I installed Concours bars on mine along with longer clutch cable.
