These are the HWY 1 bags made by RKA. They are expandable and have the rain covers included.
These bags came with a BMW R1200ST that I purchased used 3 years ago. The bags have no damage (may have very slight fading on top of bags... I honestly can't tell.) I have never mounted these on a bike and they look like they saw little (if any) use from the previous owner. They seem to be a universal fit (see RKA's website.)
