Pretty straightforward here, door edge trim from the company Trim Brite, available through most local auto supply outlets....however....
Most places only carry this trim in 27 inch long strips, and that will create seams where you will have to butt two pieces together, and that just won't do.
You can get this door edge trim from JC Whitney in a 50 foot roll, and then cut to length as needed: no seams.
You need not remove the fenders to trim them, but it is easier and neater to remove your seat to do a complete piece all around the underside of the gas tank.
Pick a warm, sunny day, park the bike and the roll of trim in the sun for awhile....this will make the trim more pliable, and easier to install.
