The MV Agusta F4 is a pretty good motorcycle: some reckon it’s the most beautiful bike ever made. But human nature being what it is, someone will try to improve it. The guilty party here is an Italian company called Aurum, which has covered a perfectly good F4 with 24kt gold leaf. We’d love to know what Massimo Tamburini, designer of the F4, thinks of this. If you’re going to spend silly money on an MV Agusta, you’re better off tracking down an F4CC “Claudio Castiglioni”. It’ll cost $120,000, but at least they’re only making a hundred of them.
