One good reason to hang a helmet on a foot peg versus a mirror - if it falls off it is a far shorter drop!
I use the helmet lock or for long term will thread a cable through the face bar and lock it to the wheel. But most of the time I just carry it on short stops and errand running. Makes a great small grocery basket.
Putting it on the mirrors is just too unstable as is hanging it on the grip. Barely better than sitting it on the seat.
Ever get lost? You know, that good kind of lost - come to a dirt road intersection and you have no idea where you are or which way to turn? I like when that happens!
