Oh wow, brings back a lot of memories for me this one! My son, then aged about 7, stuck that little green smiley on the head tube. I thought that it was rather fitting so never removed it. Great to see other owners after me thought the same.https://www.retrobike.co.uk/threads/18-1998-kona-hot-frame.211313/
This is when I sold it, a few good pics of it
