I have been waiting for this rack for a while. I have told a couple of you about this so I thought I would post a thread so you can see it in a little more detail than the manufacture shows on their web site. It is a Hattech luggage rack for the R1200s, it goes in the place of the passenger seat. Here is the manufactures URL.

Thanks to R1100SPORTour for telling me about this rack.
Hattech has been wonderful to deal with. They are very friendly, and respond to emails quickly. Shipping is slow due to the USPS, customes, and probably a slow boat, so if you order one of these, be patient. UPS costs ~ 150 Euro so it is worth the wait. Mine took 7 weeks to get here. We thought it was lost because the United States Postal Service tracking had not seen it since 15 May.
This is a well built, nicely finished quality item. The pictures on the web site do not do it justice. It fits well, and hopefully will carry all my gear to TOR next month.
Here are some shots of the bottom.
Here you can see that the rubber feet are adjustable so it will fit nice and snug. I did have to adjust these, and all the bolts that do not have lock nuts I removed and applied some locktite.
Here are some shots of it on the bike.



I will come back and update this thread after I have had a chance to load this baby up and go for a ride. I think this will be just the thing as there are not a lot of good tie down places on the back of the R12S.
