The left and right bags on the Concours are slightly different due to the backside shape. They are about 32 / 34 liters as I recall, plus or minus a little. You can figure it out more exactly if you want to by laying them open and using a 1-liter bottle to fill them with water and count hopw many bottles it takes. That's how I did it, but I didn't write it down so I don't rememeber exactly.
You'll love the V-strom. It seems a lot of people own both a Connie and a 'Strom, don't know wy that is.
Here are some pics of my Wee-Strom, one with the Givi E21's and one with the E36's. The trunk box is a Givi E460 which I swap between the two bikes.
