Outback Motortek does not make a rack for the CB500X, nor do we have a Mosko adapter plate for this bike.
For a recommendation, SW Motech PRO racks can be adjusted to work with our bags. We have no confirmed fit, however. The wide and high exhaust may cause an issue. For example, the Hepco&Becker racks are too close to the exhaust for our bags.
Another recommendation, our Reckless 80L Revolver, and Reckless 40L V3.0 do not need a side rack and work great on the CB500X. All you would need is a small top rack to attach the rear straps of the bag.
