Bought this for my Yamaha R6 and it fits absolutely perfect. It survived a multi day 500+ mile trip to Scotland and even when giving it the beans it never shifted or felt like it was going to come off. I packed for 2 nights and didn’t even need to extend the bag. Perfect for those bikes with removable rear seats and lack of mounting points for cords. When you want to remove the bag you just keep the straps under the seat ready to fit it again the next morning.
