Well, not to be a smartass, but you have two choices.
You could get the manual and read it, but if it's anything like mine, it won't detail the procedure.
Second choice is to start by removing the seat. That should let you see what else is hung on to the rear end.
Look for everything else that is hung on the rear fender supports and unbolt it all. That might include rear luggage, turn signals, maybe some other stuff.
Once you have everything disconnected from the fender supports on each side, then wiggle the fender gently and see if it is connected to the frame anywhere else. If it is, it may very well be at the front lower end, with some kind of bolt through the frame, or a bracket connected to the frame, or maybe it's bolted on to the frame top cross tube.
From there on, it's kind of guess and God.
Best of luck :brows:
Don't worry. Someone who actually knows what they are talking about will chip in soon :sofa:
