The debuting Vincent Black Shadow-motored &quot;Black Falcon&quot; is the stunning creation of designer/fabricator Ian Barry (center, with business partner Amaryllis Knight) while others admire the one-off masterpiece.  Paul d&#039;Orleans bends to check out the rear of the bike, while Herb Harris (red jacket) talks with Barry and Knight.  Stephen Pate (far right) worked on the bike&#039;s heart, balancing every moving part of the engine to within 1/10th of a gram.
