Wayne Rainey gets the lead and opens a small gap in the first lap, with Kevin Schwantz moving into second to chase him down.
Wayne Gardner and Freddie Spencer go off-track, but get back in the race, while Doohan has a mechanical and Pierfrancesco Chili crashes out.
Rainey is so committed to staying in front of Schwantz that he does a downhill wheelie on the approach to the hairpin; on this lap alone they swap the lead at least 5 times.
Last lap sees Rainey ahead on the straight, but Schwantz passes into Turn One and manages to hold the lead to the finish line.
Crossing the line, Rainey’s arm-flailing betrays his fury, but he manages to extend a hand of congratulations as he comes alongside Schwantz on the cool-down lap.
