I found this in my driveway a few days after my '19 Bobber was delivered. I can't think of anywhere else it could be from. I searched high and low but don't see anywhere obvious that it might be from on the bike. Thought some of you that have done some wrenching of your own might recognize it and if not it's probably not from my bike. But its a pretty distinct stud/nut combo, with the stud portion having an end that fits a 4mm allen wrench and the nut portion takes a 13mm wrench. Familiar to anyone?
