Just looked at my 06 and even if your bags are locked and you do the retro fit with the 1/2 bolt on the fender speed nut and all. All the thief's need to do is have a 1/2 gear wrench with them and they can unbolt the brackets that hold these bag mounts to the frame right below the seat!!!!.
That's the only reason I haven't already done it. I have to take off the right bag to check tire pressure, and the left bag to air up the suspension for two up riding. Would be a major pain in the butt as much as I take the bags off.
I guess if you were real lazy you could just go with 1 bolt on each side and leave 1 pin in.. But it will probably only save you 30 seconds..
It's not a "major pain in the ***" to remove the bags once you secure them with fasteners other than the Dzus fasteners that come on the bike from HD ... A 5/16 bolt has a standard 1/2 hex head and I'm sure that all of you/us have an old 1/2 inch wrench laying around in one of the old tool boxes, or the "junk drawer" in the kitchen ... It only takes a few seconds to loosen, then remove the bolt ... It really is cheap insurance ... and believe me the thieves aren't only in the Vegas area as the other thread stated ... They're everywhere!
Not to be difficult but if its this easy to remove the bolts I ask again whats the difference if you just lock the lids. Seems you would have to do something more then just put a nut and bolt on.
