I say get one, then mount a Givi base plate to it, and put another E52 on top. That would be awesome!

Ok, but seriously...it's about as sturdy as you'd guess looking at it. I put a similar piece on an E50 a long while back, and I used very large washers on the inside and outside to go for max load distribution, and I never had an issue. I tied a tent and a bedroll to it and it was perfectly solid. If you do try the above idea, get some video.
