I just got the bag and put it on my 2008 Honda Shadow Aero with a Mustang Touring seat. It fit perfectly and the straps were easy to attach to the bike. I'm not sure how soon I will get to use it because of the fires here in California and COVID, but I'm already super happy with the purchase. It is a well built bag with lots of room and features. Depending on where I place it on the back seat, it can even double as a very comfortable back rest. I can't say enough good things about the bag. In terms of the size, I am happy with it because I thought it might look unsightly on my bike if it was too big. Now that it is on, I like the way it looks on there in combination with my saddle bags. It is just the right size. Kudos to Saddlemen for the design of this product. I hope to get many years of use from this bag.Update: Just got back from a two day, 1000 mile trip from California to Arizona and back. Could not be happier with this bag!It performed great, just the right pockets for all my stuff. What is even better is that I mounted it in just the right way so that it provided me with super comfortable back support. Awesome bag!! I highly recommend this bag.
