I sent a picture to Brock himself, so that the bike filled the whole frame in bright sunlight, and you can see all the carbon fiber.
Seriously, the only thing on mine not cf now is the battery cover, and it will be cf next month. That little top tail piece, nobody does because they break immediately. In fact, if you aren't careful, you can break the ABS plastic OEM piece too.
So I'm leaving it alone. It will be under a top case anyway, lol.
