Although this is car related (its from Pebble Beach) it gives you a basic idea...
A concours d’elegance is, quite literally, an automotive contest
of elegance.
To contend in the Pebble Beach Concours d’Elegance, an automobile must be a well preserved or accurately restored vehicle still quite capable of doing what it was meant to do—be driven. It will almost certainly have some historic value—perhaps in its day it served to debut new technology or new styling trends or it has an amazing racing record. And it will be rare—possibly a singular example of a special chassis bearing a respected coachbuilder’s art.
A VERY well kept or restored car or bike can be entered in a regular Concours, but it has to be better than the day it rolled out of the factory!
