Thanks guys for all the replies - I guess I wasn't too specific with the original question, striped fenders on the C5 Classic. I recently sold a C5 Chrome, yes that model does have stripes on the fender.
My quandry right now, is I regret selling my C5 black/chrome, and am looking to replace it. Right now, it's either another black/chrome, or, a black C5 Classic. Poking through the many internet pictures I ran across some pics of the C5 Classic with the white striped fenders, and wondered if that was specific to a certain year, etc. Motomataya put that question to rest, they weren't available from the factory that way.
I have an chance to pick a new, 'left-over' 2012 C5 black/chrome for $500 under list .... tempting.
