With an off-weekend for the AMA 125 Nationals, Team Honda's Johnny O'Mara decided to take a trip to Fraunfeld, Switzerland, to race the FIM 125cc Motocross World Championship. He met up against Eric Geboers, Suzuki's hottest prospect to keep their 125cc world-title-winning streak going that started in 1975 with Gaston Rahier. O'Mara, a hero for Team USA at the previous year's Motocross and Trophee des Nations, dominated the race, winning both motos for soon-to-be 125cc World Champion Geboers.

At the San Jose SX, Yamaha's Damon Bradshaw scored the win over Honda's Jeff Stanton and teammate Doug Dubach, with four Suzuki riders following: Guy Cooper, Ron Tichenor, Brian Swink, and Denny Stephenson.
