This is off my Gen 4 RR and is in excellent condition. Also fits S1000RR (K67) ? S1000R (K63). Its 1.5 Ltrs and is perfect for getting a phone and a wallet in with a bit of space left for a small puncture repair kit if needed. It fits to two of the forward tank screws (swapped out for the specific fasteners, included). No need to remove when filling up as it clears the fuel cap. I found it perfect for days out and it never budged. Includes a waterproof bag to put the contents in. These are ?96 new, will take ?50 including postage in the UK.
