It took place on the weekend of 23–25 August 1991 at the Masaryk Circuit located in Brno, Czechoslovakia.

Wayne Rainey on pole, his 6th for the season; Mick Doohan 0.1 seconds behind.

Doohan sets the fastest lap on the 8th, and Rainey is still with him.

Rainey on how to beat Doohan: "I'd just sit on his wheel in the middle part of the race, and I'd make sure he could feel me, so he’d have to work his front tire harder, braking later and going deeper into the bends.

As the tire got used up, his bike'd start to push and run out wide.
