You would indeed need 4 separate molds (with at least 2 halves each) to produce these and they appear to be made from a solid llow-density flexible plastic (for less weight) with a solid skin that's closer to the cladding. I'm not sure what process was used to originally make them. They could be reproduced through an injection mold (expensive) or some type of lay-up, but I'm not sure how rigid or forgiving they would be either way. To reproduce these would be very expensive, I think.

Carbon fiber could be an option but I would hate to see what these would look like after a year of road crap being slung against them. They do add tremendously to the look and functionality of the VX.
