These Crash bar bags are made for all R1200GS ADV 2014-! It is always a set (2 bags) one for the left and one for the right side. A brilliant bag for overalls, spare gloves etc. Really looks good on the new R 1200 GS Adventure.
The bags are just put over the tank bracket and fixed in place with one Velcro fastener.
