As the headline says, this product is well made, has lots of space and pockets, and yet is not too big to fit between the handlebars of my BMW R1200RT. I had the small size Fly Racing tank back (which is also an excellent product, BTW), and I was impressed with the quality of the small one, so I decided to get this one, since the small size is a bit too small for me.If anything, the medium bag is even better. It is made with heavy nylon material, and has plenty of very powerful magnets to hold it onto your tank. Except, my tank is plastic. I solved that by folding the magnets under the tank bag (the magnets are conveniently opposite poles so they attract and hold the flaps in place - nice touch).I bought some 1/8' neoprene adhesive pad (from Amazon, of course), cut it to shape, and glued it to the bottom of the tank bag. I used the included straps to strap it to the tank. Now it's secured and won't go anywhere, and I have a lot more space to bring miscellaneous items along, and in a very convenient place.If you have a touring bike with a plastic tank, and want a tank bag that won't interfere with your handlebars, you can't do much better than this one. Would definitely buy again (thought the price was fairly reasonable given what you get with this bag).
