I have the Axio Hardpack Tail Bag I bought from newenough.com and I think it is perfect for the zx14. It fits the passenger seat perfectly straps on securely with the velcro straps ( mine has been on for a year now with no movement at all ), comes with a strap to carry on your shoulder and a net that hooks to the bag to carry a spare folded up jacket or something about that size on top, its not waterproof but I gotten it wet lots of times and nothing inside has been wet yet. It even has a little butt pad for support when you' re riding a little quicker than usual ( not that I ever do that ).
