IMHO, over time, the durability of anything painted is less than something chromed.

Vic had a CC last year that was red with black pipes, black accents, etc. Sharp looking bike!!! I saw one that was 'used' for a few months and the black was already starting to transition into gray. Not much, but noticable.

Fade rate will also be differnt in different materials,,, ie where hard plastic meets 'rubber' mount (Vic t-sigs)

Black is ~nice~,,, if it stays that way,,,
