My left side bag would not come off. I took it back to NPR Ducati near Athens Ga and Daniel the technician took the bag off from the locking mechanism and spent over an hour trying to get the mechanism to work without success. He had it so that it could be reattached to the bike but it would not lock! A call to the Ducati regional rep. left us with " we haven't heard about this before" I have seen it on this forum and it is obviously a problem. The owner of NPR has a demo Hyper and just last week while taking a trip lost his bag and watched it bounce down the road behind him!! The locking mechanism will be replaced under warranty and hopefully that will take care of it, but be aware that it is a problem and potentially could launch your side bag off the bike as you are riding! Anyone else having issues with the lock? Seems like an overly complex design to me. The locks on the Multistrada are simpler and more effective.
