Excellent bag. I have looked at this bag off and on for the last two years for my FJR1300. My son recently bought one for his FZ6R. He loves it. When I got to look at it first hand I decided I had to have one.
Very well made. Great attachment provisions with included adjustable bungees. It is definitely expandable and it comes with a nice rain cover. There are extra small pockets and compartments inside that are very handy. I have a custom made cargo rack on the tail of my FJR and this sits perfect on it. My last bag was very nice but it was a stand up type and it stuck up above the backrest for my passenger. The Cortech is lower and has a stream line look to it.
Very pleased with this bag. I haven't had it in the rain yet, but I'm sure the rain cover will work just fine.
