There is a member on here that has these bags on a kingpin with the oem quick release brackets. They're notreally made to go together, but will work. They sit higher up on the bike, and look kind of funny to me because of it, but that's just personal preference. If you use ghost or edge brackets (brand names), the bags will not hang vertical to the bike. They will point out at the bottom like an upside down V.
