The best sidebags for it are the OEM.
There are often sets on eBay and any year will fit but will be a different colour.
Once you get them, pin them through the front mount to prevent them coming off.
As for top cases, most fit Givi. A few vendors sell metal racks that you can bolt the Givi mounts to.
Mine has a Maxia 4 but then I rarely use the sidebags.
