Hi without seeing the instructions I should think that you do not remove the entire rear of the bike but simply bolt the bag carrier ontop of the original frame. Can you post picture of instructions?

This may help - ignore the stuff about wiring etc but he shows how to remove fender - bolts on side and underneath

Hi
I think I see the issue- The instructions etc are for a Scrambler 800 which does not have the metal bracket under th seat for the number plate and light (on its own big bracket on swing arm) You will have to remove the all the bolts holding your light/ plate bracket and then you can remove the fender

Yep those bolts need to come out - as for the loctite issue - Ducati likes to use a lot so good fitting wrench and pray
