I purchased the Harley half SAC so that I could have a little more space to carry a few things while riding. It has no locks of any kind. Does anybody have any suggestions for keeping it locked somehow on the bike ? I think that it would take someone just a couple of minutes to just unhook it and walk off with it. I found a small luggage style padlock to lock the zippers together, but the actual sac just quick connects under the passenger backrest and luggage rack. I bought it more for being able to carry stuff when down in Fla, but am having second thoughts about leaving it on the bike while in Daytona.
