I recently purchased the Tour Master medium slant "zip-off" fabric saddlebags for my '06 S50. Even with the bags empty, they can come unzipped, especially at highway speeds. Yesterday, with no questions asked by the friendly owner of a local motorcycle parts store, I exchanged them (with some money back) for what I should have bought in the first place: the River Road compact, with "quick-release" buckles, synthetic leather studded saddlebags.
