    I have been looking at that standard rack and wondering how to get a box on to it and still have access to the seat lock. I would hazard a guess that it has been done before (quite a few times) so I am interested in how. I am sure that there are some adapter plates out there and some decent home made designs.

    My preference is always towards the budget end but interested in anyone's experience in fitting a top box to the BMW rack that is integrated into the subframe. :ear

    Interesting - wonder it it has a bespoke mounting plate or a homemade adapter to mount the box. Still havent figured one out for mine but that may have to become a winter "project"

    Now that looks like my original subframe/rack, will have to devise a way to plate it high enough to be able to get the key in the seat lock but no higher so the box is as low as I can get it. Cheers

    I've got an R80ST and I used to have a girlfriend who if she wanted to ride on the bike she had to have a back rest.

    I spent some time trying to figure out the best way to make a mount that wasn't permanent, wasn't super ugly, and that I could mount a Givi monokey plate to.I had no welding or serious fabrication tools,
    I was also pretty broke,

    The idea I came up with was clamps for the forward grab handle
    Then extruded aluminum box tubes notched at the bottom to fit around the cross bar of the rack. "L" brackets at the top

    I used a hose clamp that held the square tube down onto the rack.
    For the "L" brackets I used steel, since it was slightly more forgiving for vibrations and I didn't want it to fail at the corner of the "L" bracket.

    Thanks, it was pretty and we didn't go out very long so there wasn't photos taken of the set up or I would have posted em up. It was up to normal top box weight holding and didn't shift around too much, but the weight was high on the bike and further aft then I like it to be.
