I painted my own helmet to match my Copper Busa... I don't have a picture of it right now. I couldn't stand the fact that I was riding a bike with a helmet that doesn't match. It turned out pretty good too...
You can get one painted by anyone who knows how to paint, you can get the paint yourself from ColoRite or anywhere else, so that it matches perfectly.
Otherwise, good luck! I saw the Suzuki helmet that matched my bike, but it had avery other color but copper... well, it did a little bit but I think it looks like crap.
