I've found that Motul Shine and Go silicon spray keeps the black plastic components like new. I also use Autoglym Super Resin Polish on the paintwork and Autoglym Show and Shine on the (stock) seat and the chrome. Haven't decided on what to do with the wheels yet. Buggers to get at actually. Wish they'd made them matte black instead of gloss then the brake dust wouldn't matter so much.
