I have been using it for quite some time on the Z. In combination with the Trax side panniers. Very pleased with it so far. It is quite sturdy, does not look too obtrusive and removal/installation of the quick-lock is quite simple and fast. (I tend to remove it when I go play in the dirt)

For the top case I just installed a Givi base plate as I still had a Givi 52L and a 46L top case lying around.

The combination of both served me well during a 6000km tour around France and Spain last month.
