Rainey is using carbon fiber brakes for the first time, which had only been tested and not raced on.

Kevin Schwantz is in around 8th place and tries to pass two or three riders simultaneously at the chicane, but crashes into Ron Haslam and causes a bottleneck.

Haslam struggles to get out of the gravel and back into the race, and Schwantz is out with a broken kneecap.

Randy Mamola and Norihiko Fujiwara come together at the hairpin, but stay up.

Rainey is maintaining a gap, and Gardner makes a mistake at the chicane and lets Sarron and Mackenzie through, but he's soon back to 2nd.
