I purchased this for use on a 2009 Vstrom 650 because of the great price and size. The bag was a little longer than I expected. For the Vstrom, the rear magnet of the bag must remain folded under the bag(magnet will not hold to bike like this), or slightly tucked between the tank and the seat(not ideal, but works). It seems very well made...the only problem I had was the map pocket zipper handle was sewn to the bag by the neighboring stitching and had to be cut loose and some additional stitching done to keep the seam from unraveling. The main zippers are tied together for one handed opening, but kept binding so I cut the strap between them in half and use each zipper separately. The many pockets available are a bonus...except for the pocket at front which is nearly useless when the rain fly tucked away.
Overall, I like the bag and think it will serve its purpose well on my bike...really can't beat it for the size, price, and quality... even if it does has a few flaws!
I wanted a small tank bag because I have plenty of storage in the hard saddlebags, and this bag is perfect. It's easy to open with gloves because the zipper pulls are oversized. I got the strapped version because half of the bag sits on a plastic cowl. I like being able to unsnap the map pouch and store it in the bag since I use a GPS. Great deal for $27.98 (including shipping).
