Do motorcycles carry us to future, or past?

A Royal Enfield Military motorcycle photographed next to a stylized chopper is one of my favorite pictures seen on eBay recently. The Royal Enfield has been relisted, and the seller has included yet another photo, seen here, of the odd couple.

The olive drab Military, intentionally vintage in appearance, and the futuristic fantasy bike could not be more different and still both possess two wheels. As I said before, both are eye catching although the Royal Enfield is deliberately camouflaged and the chopper is scarlet in color.

The motorcycle store has unintentionally produced an artistic statement. What do these two motorcycles say about why we buy motorcycles?
