When youâ€™ve parked your bike what do you do with your helmet? Do you use the helmet lock on the bike (if it has one), take it with you or have a big mofo lock and bolt it to the bike. I found out my Hornet has a piss weak helmet holder, so for now take it with me. So I was thinking of getting a length of thin steel cable to padlock it to the bike. And has anyone had their helmet stolen from their bike?
