Odsal Stadium hosted its second World Final in 1990. Swedish rider Per Jonsson won his only World Championship when he defeated Shawn Moran in a runoff after both had finished the meeting on 13 points. Moran was later stripped of his silver medal by the FIM after he had tested positive to a drug test taken three months earlier at the Overseas Final in Coventry. Moran claimed that the drug he took was a pain killer prescribed by a doctor in Sweden, but the FIM stood firm. They also did not upgrade the standings and the official records show no second place rider. Young Australian rider Todd Wiltshire riding in his first World Final surprised many by finishing in third place with 12 points.
