I've had Ghostbrackets on my bike, before and after the 250 rear end. All of hardware was fine. Yes, it is possible with very light bags that they could move up and down. Ghost brackets lock too!8-Ball said:Ghost brackets suck. They don't come with the right hardware so you end up having to go find your own, or call them and they will send you the right size bolts... if you want to wait. Oh... and your bags look like they have a life of their own as they jump around.
Take a look at Boss Bags. I think they will give you much better results.
