BMW OEM tank bag (tankrucksack) for sale in good condition. I used this on both my 2005 and 2013 BMW R1200RTs. It should work on all models that have tank rails. It is expandable at both the front and rear so can hold an enormous amount of gear. Also a nice map pocket (does anyone use maps anymore?) and a zipped pocket inside the lid for passports and paperwork. A bit dusty, but otherwise in great condition. No tears and all zippers work as they should. I found this review on Utube. It gives a good overview of the bag. $125 OBO
