I plan to try to remove the headbadge sticker when I have my Peugeot painted and then have the painter reapply it. It's a foil sticker and I think I can remove it by applying heat from a hair dryer. I have the new decals for the rest of the bike.
My Chevy truck was plastered with vinyl graphics at the factory. I took them off with a hair dryer as soon as I got it home.
