Jeff Heino (13) leads a group of riders in the AMA Superbike race at Riverside Intl. Raceway on April 17, 1983. Also visible is David Aldana (40), Roberto Pietri (11) and Wayne Rainey (behind No. 40 Aldana). The Suzuki GS750ES was fairly rare in AMA Superbike competition with the Honda V750 dominating the grid along with a fair number of Kawasaki KZ750s and GPz750s. 1983 was the first year AMA Superbike went to 750cc multi-cylinder machines. Everyone who still had 1000s Superbikes had to move up to race the AMA’s Formula 1 class.

The Suzuki was a very reliable platform to race and was in my opinion as fast as any Honda. I had a lot of success racing one in both the wera and amaccs endurance races in 1983 thru 1985.
