I've got a Touratech Streetline bag for sale. I've had it a couple years, only taken on two trips, before I sold my bike and bought one I didn't need it for. Time to clear it out. Has a mount that velcros under rear seat, bag zips to the mount, so you can take it on and off pretty quickly. I'd like to sell it locally in Seattle area if possible. $40. If you want it shipped I can (on your dime).
