This is going to sound very silly, so take it all with a grain of salt.
When I bought my K1200GT in 2007 with the 49 litre top box, the dealer rolled it out in the showroom with the top box already attached to the bike. Still, I wanted all of the materials, instructions, supplies, boxes, everything, etc. so they gave it to me. (we put the bulky items in the car for the trip home).
Riding home was an eventful story in itself. (See "First Ride" in BMWMOA, September 2009.)
After I got home, I began to go through all the materials. There was an instruction manual that came with the top box, and here are the parts listing for Topcase, large:
* Retrofit kit: Topcase, large; Installation instructions.
* Protective strips for the luggage carrier of the K 1200 GT; luggage carrier if applicable.
* Also required: Lock barrel with key - 1 set.
I noticed the "protective strips" and noticed that they were missing, so I went back to the dealer and asked for them. They told me that they never install them, that they throw them away. They couldn't even figure out WHY they apply to K1200GTs but not the corresponding K1200RTs with the exact same tail rack configuration. I told them that they must be in the manual for a reason, and I wanted my protective strips.
So I insisted. I didn't want my brand new K1200GT tail rack unprotected (from what? scratches in the black plastic?) but that manual said "Also required" so I asked the dealer to provide them.
I told them that they could get them from the next RT they sold, since the protective strips are not required for the RT. A few weeks later the dealer gave me a yellow paper with four odd shaped thin clear vinyl stickers on them. I don't even know if they were the "real" protective strips from a 49 litre top case. They didn't match up with the black plastic on the rack all that well, but I put them on anyway as best I could. Frankly, I couldn't tell the difference on or off, but I left them on because the manual said so.
They are still there. They feel like the clear vinyl stickers that you can buy to protect your cell phone screen. They are fairly thin, but there is a rubbery feel to them.
I have not had issues with the top case coming loose, and perhaps it is the protective strips adding a slight extra thickness on the black plastic along with the extra rubberiness that has made the difference. Most likely not, but it wouldn't hurt to try.
Buy a thick cellphone vinyl screen saver for a couple bucks, and cut it into four pieces that fold over the four shiny black plastic bumps on the top of your tail rack. Most likely it won't do anything, but it can't hurt either. Why would those infallible Teutonic engineers specify them if they did not think they were needed. :-)
