The AMA 125/500 Nationals went off at Spring Creek in Millville, Minnesota, and Team Honda's Rick Johnson topped both motos ahead of Kawasaki's Ron Lechien. Yamaha riders Keith Bowen and Jeff Stanton were next.
In the 125 Class, hometown hero Donny Schmit, a true rookie, led a Suzuki sweep of the podium, as George Holland and Erik Kehoe followed. Schmit won the first moto by 20 seconds; Kehoe, the current Honda team manager, took the second moto. Series frontrunner Micky Dymond of Team Honda would only finish 13th overall with 6-DNF moto finishes.
With the AMA Nationals on break, Kawasaki's Mike Kiedrowski was dispatched to Suzuka, Japan, to race the final round of the FIM 250cc Motocross World Championship. He ended up winning the three-moto race with 2-1-4 finishes. The other motos were won by Peter Johansson and Alex Puzar. Chesterfield Yamaha's Donny Schmit, who long ago clinched the title, finished third in the first moto.
Honda's Trey Canard won the Salt Lake City 450 National at Miller Motorsports Park in Utah over Red Bull KTM's Ryan Dungey. Canard's Honda teammate Eli Tomac finished third with 4-3 scores. The Utah win turned out to be 250 National Champion Canard's last outdoor national victory. And that year's series champion, KTM rider Ken Roczen, finished fourth in what turned out to be his last ride with Red Bull KTM.
