This is weird, I'm certain I replied to your post this morning.
If you are referring to the small, 1" x 1" or so raised Union Jack decal, that is available at your local dealer. They come on some the the sportbikes bodywork pieces. I put mine on the sidecover. It's raised up a 1/4" or so, but has remained securely fastened to my sidecover for over a year. I believe they are about $8 or so. I've been meaning to pick up a pair for the back of our helmets.
