What did you do on or to your other bike part 2

[Gone in 60]

Very slick way to lock a helmet. I have bar end locks on two of my bikes, and one mounted under the Givi trunk mounting plate on the Bonneville, as that bike had bar-end mirrors for a long time. I'm putting hand guards on the NC, and was planning to put a LidLox under the Givi plate on that bike. I have a bunch of matching lock cylinders, so they're all keyed alike. I'm seeing this one on Ebay, might have the same diameter lock and thread pitch to screw it in. Work looking into, even if the locks are not compatible and I'd have to have a unique key for this one:
