I might (almost) be as pi$$ed as Cherokee at this (he had already shared it with me in PM) - the total disregard for a 'fellow' biker, just disgusts me.
The fact that thief was bold enough to do this in broad daylight is just mind-blowing.
Regarding 'Frenching' - Can't see the OEM bucket being conducive for that; at least certainly not with the 7" lamp - you might be able to do something if you use a 5-3/4" lamp module (as per the size used on the Twin Headlight Classics & Roadsters) in that bigger Touring bucket
Edit - ignore that last bit - I was thinking of a traditional 'frenching' - I guess with bikes you can buy a trim ring that instead of recessing the lamp into, just extends the shell outwards for same appearance, to look like is recessed.
Lots of those on places like J & P
Was this just aesthetic plan or were you thinking might add some security (which I can't see how would)
