Cargo stability problem solved!

Actually, Rivco's online ad (see my link in post #1) and their printed materials that come with the bracket state that the load limit is 12 pounds. The only 20 pound mention for the rack that I've seen was on youtube. So, regardless of what the trunk's limit is, the bracket itself isn't made for that kind of weight. Just sayin'.

The 20lb weight is for the trunk in general ,rack or no rack. My point was that 20 lbs is 20 lbs whether you have it mounted on the lid or in the trunk.

I'm guessing it has to do with the way the trunk is constructed and attached to the bike's frame. That, and the fact that more than 20# that high up will really mess with center of gravity!

It really isn't connected to the frame. The best I can discern from the service manual and parts diagrams all three of the rear luggage pieces hang off an H shaped FRP piece that sits on top of the frame. The entire rear cargo module is connected to the frame with 4 bolts. The bottom edge of the trunk is fastened to the rear edge of the H piece so in effect the entire trunk weight is supported behind it's mounts. It's cantilevered off the back end of the frame making it more vulnerable to up and down bouncing forces. Of course there are other plastic pieces fastened behind and on the sides but I wouldn't call any of them structural supports.
