very interesting, the single bike is a F9 Big Horn 350cc on a A7R frame, very competitive in 250cc class in USA as rules were twin 250cc single 350cc, on the picture on which you see Didier RAVEL, brother of Christain RAVEL you see also right side left hand PC a woman with short hair. She is Anne-Marie LAGAUCHE who raced on endurance on Kawasaki H1 H2 and sadly crashed on 24 hours of Montjuich 1975. She is tetraplegic.
