After cleaning the black downpipes on my FZS600 I would give them a coat of Zebo black firegrate polish, leave for an hour, then buff to a semi-shine. Also works well on the black parts of your brake calipers if they're looking a bit grubby. Work it in with an old toothbrush and buff off with a shoebrush.
Wear gloves, though.
