Very good quality, easy install.

Somewhat difficult to install, but worth it...

Things to note for the install:
1. The directions say that you may have to remove the passenger peg. I'd say that's an understatement. I don't see how this bag could even be mounted and usable with the passenger peg OR the peg mount still in place on my 2009 Super Glide FXD.
That said, mine is strictly a solo bike. I didn't want passenger pegs on it anyway, so I had a machine shop cut the peg mount off at the belt deflector mounting tab. This way I could still mount the bag and retain the factory chrome belt deflector without having the peg mount and peg in the way.

2. You'll want to mount the bag as far to the rear, (close to the spring), as possible so you can get your boot heel on the jiffy stand extension to deploy the jiffy stand and to minimize heat from the primary cooking the contents of the bag. The problem in doing this comes into play when you're drilling the holes in the bag for the bolts. The way the material is stitched along the side seams makes it very difficult to drill the holes close to the edge without going through the side of the bag and even more difficult to get a wrench in there to tighten the nut afterwards.

I saw someone stated that the holes in the mounting bracket didn't line up...that's incorrect. They line up perfectly, you have to snug up the lower mount (peg mount) first. Push the bracket a little bit rearward before starting the second bolt (deflector mount) and then pull the bracket forward and tighten everything down. It's really a solid mount once everything is tightened down.

When marking the bolt holes before drilling, please check several times to ensure the top of the bag is below the bottom of the fuse box cover as it will be drawn toward the frame under the fuse box when tightened down. Make sure it's close to, but not touching the spring. And make sure no holes are so close to the edge that you won't be able to tighten the nuts down after drilling.

The bag itself is very small (to be expected given its intended mounting location), and is suitable for smaller items such as: keys, phone, sunglasses, garage door opener, rotor lock, etc... So don't expect to keep much else in there like tools, rain jacket or ball cap.
That said, the bag will suit the purpose for which I bought it. It does look good on the bike. And I don't think there will ever be a concern about it falling off or even being stolen for that matter as it's very solidly mounted and secure.
I recommend any products made by Viking Bags as this is my second or third purchase from them and everything I've received has been superior quality at same or better price point than their competitors.

Viking swingarm bag

Looks great , but was difficult to install. the belt cover bolt hole did not line up with the bracket provided for my 2012 Fatbob. I had to rig it up with a smaller bolt and nut.
