Doohan takes the lead; Rainey getting dropped. Serious accident for the Italian Corrado Catalano, he fell, was hit by his motorcycle and for some days was in a comatose.
Doohan has a mechanical problem and drops out; Shinichi Itoh passes Crivillé for 3rd, with Schwantz in 1st and Beattie in 2nd.
Into the last lap, Beattie is in front of Schwantz; Itoh twice comes alongside Schwantz and thwarts Schwantz’ attempts to brake-pass Beattie. Itoh becomes the first rider to pass 200 mph in a speed trap.
Schwantz seems happy with second because Rainey is so far behind, and is now 14 points behind Schwantz.
