500 cc race report
Wayne Gardner was on pole, but Eddie Lawson got into the lead at the start, ahead of Wayne Rainey and Kevin Schwantz. Back in 6th place, Gardner was almost cut off by Pierfrancesco Chili, who tried a block pass on him; Gardner shook a fist.

Schwantz got around Lawson for 1st, but Lawson looked like he's not going to let it go. Gardner caught up to make it a trio, while Lawson retook the lead. Randy Mamola was hot-dogging, deliberately sliding the rear. Schwantz and Gardner went at it for 2nd place. Mamola almost highsided trying to impress the crowd, a bit later on a left-hander he looked over his shoulder and immediately slid the bike into a highside. Schwantz will do something similar next year at Phillip Island. Rainey retired with a punctured tire.
