F04 and F05???? Factory bikes as in race bikes? They'll use the pierobon bracket and it's a nosecone and sides with a seperate belly pan.
Or do you mean MY04 and MY05 "road" bikes? if so yes as far as I am aware it's merely cosmetic for the R model, the R model also came with slightly wider nosecone over the other models, but all models from 05 onwards had the same width.
The easy answer is yes in theory
