Fourth roundBritish/Commonwealth FinalNordic FinalFifth roundBritish/Commonwealth/Nordic FinalContinental FinalSixth roundPolish qualifiersEuropean FinalWorld FinalFinal ControversyThe Final was surrounded by controversy, with decisions made by Georg Traunspurger, the referee assigned to the meeting by the FIM, seeming to favour the Polish riders. One of his decisions was to have 2nd reserve Andrzej Wyglenda of Poland race in Heat 16 in front of 1st reserve Tommy Jansson of Sweden, making it four Polish riders in the race. In the race, second placed Edward Jancarz, who led for the first three laps, seemed to let Zenon Plech take the lead in the final turn, allowing Plech, who had more points at that stage of the meeting, to collect another three points for the win. His most controversial decision was to exclude Soviet rider Grigory Khlinovsky from heat 19. Khlinovsky had attempted to pass on the inside of Zenon Plech for the lead going into the back straight of the last lap. As he was passed by the Russian, Plech lost control of his bike and fell. Despite protests from riders and the Soviet officials Khlinovsky was excluded and England's Peter Collins, who was in 3rd place at the time of the crash, was awarded the heat win, Plech, who didn't actually finish the race, was awarded 2nd. The result of the two points he gained for second place allowed Plech to finish a clear third in the championship. Had Khlinovsky been the winner of the heat, he would have ended on 13 points, which would have put him in the run-off for the title with Szczakiel and Mauger. British television commentator Dave Lanning called the ruling "The craziest piece of speedway regulations in the history of World Championship racing", before adding that ''"It seems to me that the authorities here in Katowice are making up the rules to suit themselves to get their boys a world title."''
