I’ve not been on the Forum for a while, so apologies for a late reply. I looked for something like this about ten years ago, when I first started travelling on my LT with heavy camera boxes that were too big for the topbox.
I failed to find anything worthwhile, and settled for the BMR rack that fits across the pillion seat. That solved my problem, and did so without wrecking the bike’s handling. Sadly, I heard today that BMR (a US company) seem to be no more, but a second-hand rack might be available via the Forum, eBay, etc.
