The bag attaches to the Givi mounts* that attach to the bike. If you know Givis the bag sits on the two “mushrooms” at the bottom and the lock attaches to the “pyramid” at the top of the mount. I hope that helps.
Added after: I found the name E22N for the newer 22 liter bags. I THINK these bags were called E22s but that is my memory, not a fact.
I don’t know of a name other than “22 liter” bags. The bag was mounted on my long gone XR1200, it fell over and damaged the other bag, I upgraded to a pair of the 28 liter bags (also long gone) so I’ve had the left over bag taking up space. I saw a Zero with the 22 liter bags when was poking around the site after I joined so I thought somebody might have a use for the bag.
A new pair of Givi 22 liter bags (now more square in shape) has a street price of about $160 plus you’d need to buy the mounts specific to your bike.
*AKA carriers, racks, side racks and a few other names.
