Great rider intro shot of some of the field in the 1971 AMA Grand National at the Action Track in Terre Haute, Indiana. From left to right you have the bikes of Dave Sehl (16), Jim Rice (2), John Hateley (43R), Bart Markel (32), Don Castro (5) and Gene Romero (1). Riders are lined up counter-race direction for intros. Sehl went on to win the national on his Harley-Davidson over Castro on a Triumph and Markel on another Harley.
