My buddy had either a Ducati 916 or 996 (I forget which was the current model at the time), in traditional red.
He replaced the main bodywork pieces with carbon fiber but actually had it painted red--except for the DUCATI stencil on the sides, which were unpainted and revealed the carbon fiber underneath.
While paint adds weight, they were still lighter than the stock body panels, and made for a pretty cool effect.
To bring this into this thread's purpose, he was grumpy when he crashed it and broke both his arms.
