Bah, do something different! Buyers won't go for wild graphics, but a good-looking non-standard color could help it stand out from the for-sale crowd. I would paint one in sort of a medium-dark blue with a subtle metalflake in it, something that only showed in highlights. The stock colors are too flat to my eye.
Stock colors are chosen to appeal to the largest possible market - the lowest common denominator. By definition: boring! Millions of cars and motos, but all the same basic plain colors. Break out a little!
Yellow would be a good safety color, and not as weird as you might think. Lance328's bike is yellow, I've seen it. Looks kewl!
Laissez les bon temps rouler!
