If you look at the blue one on the Biker's Friend website that is my bike.
http://bikersfriend.com/pages/saddlebag.htm I've had one for about five years. I got the biggest one and have been very happy with it. It will carry two bags of groceries or two cases of beer, two full coverage helmets, a weekend worth of clothes with an extra leather bike jacket. (Not all at once you smart alecs

) The back rest worked great but I got one with my Corbin seat so mine isn't used anymore. After five years it still looks and works great.
