All fine and well but I think a thief would just pull up hard on the latch handle, break off the PLASTIC TAB that 'locks' the saddlebags closed (and onto the bike) and open or steal the saddlebag that way.
Locks just keep out the honest people. Security is mostly a state of mind and a collection of events and situations; if someone watched you put a GPS into a saddlebag and that person wanted said GPS, then there is nothing about a plastic saddlebag, no matter how it was secured, that would keep said person from having that GPS in a few minutes.
Personally I have always been more concerned about vandalism than theft and I am not particularly worried about vandalism.
If you are really concerned about saddlebag security and retention, do what I do and use the Kirby approved BDF saddlebag retention kit. Sure it weighs a little more but what is peace of mind really worth?



For the ultimate in motorcycle security, I suggest filling both saddlebags with depleted uranium; ain't nobody gonna' steal a motorcycle that weighs more than 7,000 lbs.
