The sticker on the top of the tank is easy to remove. Use a hair dryer / heat gun to warm it, and it will peel off. You may find a glue residue left behind where the sticker was, WD-40 on a soft rag will take care of it.
The "Rune" name decals on the sides of the tank "CAN NOT" be removed without hurting the clear coat..... they are under the clear.
One of the areas that I wished Honda had done a better job with is the "Rune" tank decal .... it kind of looks like a afterthought. Either it should be, bigger , brighter, or not there at all....
