Ron Pierce is on the bike as his Team Kawasaki crew quickly preps the team’s KZ1000-based Superbike during a pit stop for the 1981 AFM Budweiser Six-Hour at Riverside International Raceway. Pierce and Eddie Lawson teamed up to win the race over Team Hammer’s Bruce Hammer and John Ulrich who rode a Suzuki. Third went to David Emde and Harry Klinzmann on a San Jose BMW. So there were three different makers on the podium filled with national-level riders, showing the importance of the AFM Six-Hour during that period on time. (Cycle News Photo Collection)
