It fits just fine mounted that way with the grab handle still on the bike. I got mine a couple weeks ago and just used this idea to clean up the mounting for a weekend trip leaving tomorrow. I currently have a pair of tennis shoes, two pair of socks and clean underwear, jeans, thermal shirt, quilted liners for my pants and jacket, long johns, hat, t-shirt, sunscreen, and still have the side pockets and more room inside. This is nothing in comparison to the full trunk I had on my VTX, but it will do the trick. If I was going this time of year and didn't need to take my quilted liners for my gear I would have a ton more space. Erik
