The XTZ foot is like () and the XTR is <> , if you know what I mean.

They are also a little different in size. The one I got was plastic with an aluminium top plate, so was easy to mod with a dremial like tool.

There is no interference with the SW Motech centre stand with this mod on the R.

I believe the Z stand is longer then the R and may be the problem Touratech mention.
