Actually you can find three kind of bags for V11:
Hepco & Becker (the one I have): 287 euro the frame (side and top frame), 210 euro for the Junior Bags rigid 30lt. (http://neu.hepco-becker.de/Web/index.html)
Tekno bags: bags with internal frame 38lt extended (cod. BRG11) 254,09 euro, (SRG11) Euro 102,25 for the side frame. No top frame. (http://www.dragonemotorcycles.it/index.html?target=dept_142.html&lang=it)
Bags-bike: they sell exactly the same bags as tekno I think, but don't have pics. Don't know the price as they didn't told me. (http://www.bags-bike.com/)
Why did I choose Hepco?
Because of the top frame, otherwise it is better Tekno.
Why better Tekno than Hepco?
Hepco is big and needs a little cut of the mudguard. I don't like to cut anything on my bike. Next, blinker's older sits upon the rear light.
Tekno is a light seeing, no cuts required.
