I scored a set of Wolfman Monarch Pass bags to use on my Transalp when I do longer rides but since those are father apart than I care for in the meantime I am using them on my Metropolitan and they actually fit really well and added some very much needed space. Just dont tell Wolfman I put Dirt bags on a scooter or they may not sell to me anymore! I did have to make a custom x shaped strap for where they would normally attach to the wolfman racks and attach it to a frame loop wrapped around the frame under the seat The photo is from before I made the permanent strap for the back so forgive the hanging hardware but will give you a general idea of the asthetic. They fit the bike very well and stay out of the way when riding (I do have to fish my foot under them to kickstart or drop the center stand but not annoying once you figure out exactly where under the bags they are. The size of them is just right to make them look like they actually belong. While not waterproof when I got mine I seam sealed the zippers and gave them a good dousing of scotch guard and when I got got caught out in the rain a couple days ago for awhile didnt have a single thing in either bag get wet.
