The 1993 San Marino motorcycle Grand Prix was the ninth round of the 1993 Grand Prix motorcycle racing season.

Doug Chandler crashes in qualifying and briefly loses consciousness, which automatically DQd him from the race.

Doohan takes the start from Wayne Rainey and Kevin Schwantz.

They swap the front many times, but Schwantz develops a tire problem and nurses it home to 2nd.

In the battle with Schwantz, Doohan demonstrates that any lingering weakness from Assen '92 isn't enough to prevent him from riding at the highest level.
