Believe it or not I worked for a company that made this type of tape and it is called tamper resistant. It is designed to come off bit by bit so no one could destroy a sign made of it without spending a lot of time. You see in in many variations, red as well as black and yellow striped and of course custom signs as well. So far the suggestions made are all good and I can offer one other. If you paint is strong on the bike, as suggested before, leave it out in the sun to warm up a bit then take an agressive tape such as duct tape and place it over the reflective tape so it overlaps the ends. Rip it away and you will pick up a nice chunk but may have to do it over and over again. Clean residue with WD-40. This works well for old decals also. I caution that if you paint is not strong, it will come up as well. You will not peel this tape ever, it will only chip away bit by bit.
