Hi. They have 2 sizes: 1)44 x 22,5 x 38 cm (35Lt) 2)44 x 26,5 x 38 cm (45Lt). I have a F650 and as it is unsymmetric I've bought one the 35Lt one and one the 41Lt one. However, more heavy you travel, more problem you have. Thus, I am gonna sell the 41Lt one and buy a 35Lt. I have traveled from UK to Turkey with almost 50 kg of lagguage and I only used maybe 20Kg of them. I am defibately travel lighter on my next tour.
As a conclution, I recommend to you buy 2x35Lt. If you cant fit to them, it means you have too much mess with you.
