Also on this day, the AMA announced that the upcoming Trans-USA Series (previously the Trans-AMA Series) was now going to be for 250cc motorcycles rather than the Open class. They also announced that the winner of the series would get an ironic bonus: a brand-new Pontiac Trans-Am.

1997
In Venezuela, Stefan Everts took the 250cc Grand Prix overall win with 1-3 finishes. Germany's Pit Beirer won the second moto, but a DNF in the first moto cost him a shot at beating Everts for the overall.
And in the 125cc Grand Prix of Finland, American rider Bob Moore won the first moto but was a DNF the second time out. The winner of the second moto and the overall after running second in the first moto was Yamaha-mounted Alessio Chiodi, who would go on to win the world title that year.
