I actually bought this one last week. Is not as expensive as the givi and it has plenty of space, but the most important feature, in my humble opinion, is that you don't have to pay extra for the base since it comes with it. I'm planning on having this painted to match the bike's color. for a $112.00 you can't beat that compared to almost $500.00 for a givi with the base. The only issue you may run into is the type of rack you have on your bike. If you have the OEM for the F6B you may have some issues but if you have a larger rack you will be fine. I have a friend of mine making me a larger rack based on the OEM.
