1990 Yugoslav motorcycle Grand Prix

The 1990 Yugoslavian motorcycle Grand Prix was the seventh round of the 1990 Grand Prix motorcycle racing season. It took place on the weekend of 15–17 June 1990 at the Rijeka circuit.^[3]

In qualifying Christian Sarron crashed and dragged off the tarmac by track marshals, which brought complaints from riders that the race organization was unprofessional.

At the start, Wayne Rainey led, followed by Mick Doohan and Niall Mackenzie, while behind them two Cagiva riders collided and crashed: Ron Haslam and Randy Mamola. Haslam touched the back of a bike, and fell off into Mamola. After this, Alex Barros crashed, leaving Cagiva without anymore riders in the race.

Schwantz found his rhythm and caught the group of three chasing Rainey: Doohan, Mackenzie and Chili; a small gap to the fight for sixth between Ruggia and Sito Pons.

The gap to Rainey looked too big to close, and the fight for second narrowed down to Mackenzie and Schwantz. Behind him, Doohan led Pons and Chili, but Pons lost the front end on the exit of a right turn, and Chili hit the fallen rider or bike and was thrown into the air. The question of race organization came to mind again when Pons was not immediately sent for a medical checkup.

During practice Wilco Zeelenberg was severely injured in an accident that sent him and his bike up a hill into the spectators behind scattered hay bales. None were injured. Australian Darren Milner would deputise for him in the remaining sessions.

The race was disrupted by torrential rain, and it would have been stopped with two laps to go. However, with marshalls not waving red flags at all parts of the circuit, this was not properly communicated to the riders. Milner spotted a red flag in the distance and slowed down to a dangerous degree. Reinhold Roth came from behind at full speed and was trying to evade Àlex Crivillé, but he was blindsided by Milner and they collided, flinging both riders through the air over the track and collecting Crivillé from his bike mid-air. With all of the red flags finally out, riders were still lapping around the circuit, while spectators and medical personnel flooded the scene to aid the three afflicted. Milner and Crivillé were dragged away in an unprofessional and dangerous manner, but Roth was left comatose and had to be airlifted to a nearby clinic for emergency checkups. The impact of the accident left him paralysed from the waist down, and the cerebral damage he suffered would eventually lead to a fatal lung collapse in 2021.

Carlos Cardus was declared the winner.
