hung mine on the backrest, if that is any help???No, it isn't

The set of bags I got off of e-bay had two saddle bags, a front fork bag and a sissy bar bag. But since I do have a luggage rack, the sissy bar bag not only looks a bit funny back there (it sits up higher than the sissy bar due to the rack), but it also gets in the way of anything else you might want to carry on the rack. I'll probably wind up selling it since there really isn't any other place to mount it on the bike.
Cheers,
Brad
