I have it on ATas with M7 base plate (more durable than aluminum 8 or 9. Had to do some diy mounting points to stock rack (simple squared pipe with 2 holes, to adapt to hondas rack). Givi offers additional rack, which is crazy overkill for as simple as shifting couple of cm. Had several jumping offroad sessions, everything is way more solid, than givi adapter.
ps. I have bigger version trekker box and it looks just fine, plenty of space, not too wide from sides, so I don't even notice it while driving. For city riding I would just get something like soft backpack, not smaller box.
