05-12 R1200GS Adjustable Driver Backrest and Altrider Pillion Luggage Rack
100 Lott Tucker Dr
Searcy, AR 72143-5041
I found this when moving. I believe it to fit 05-12 R1200GS models (please check picture showing bottom of rack that mounts like the pillion seat). I cannot remember the brand name for the backrest but it was very expensive. I mounted it to the rack and it is adjustable. Barely used as it is in excellent condition. I know longer have my GS. I only ship to lower 48 US States by way of UPS Ground. $250 which includes shipping to lower 48 US States. PayPal only.
