Zenon Plech (born 1 January 1953 in Zwierzyn, Poland) is a former Polish international motorcycle speedway rider. He finished third in the Speedway World Championship in 1973 and then runner-up in 1979.
Plech won the Polish National Championship five times (1972, 1975, 1979, 1985 and 1986) and runner-up twice (1981 and 1983). He also was a member of the Poland to third place in the World Team Cup in 1972 and 1981.
Zenon Plech's third place in the 1973 World Final at the Silesian Stadium in Chorzów, Poland was controversial. On the last lap of Heat 19, Soviet rider Gregory Khlynovski had attempted to pass Plech for the lead going into the back straight. As he was passed by the Russian, Plech lost control of his bike and fell. Despite protests from riders and the Soviet officials, and taking no other eye witness account into consideration, the Polish referee assigned to the meeting by the FIM simply took Plech's word that Khlynovski had knocked him off his bike. England's Peter Collins was awarded the heat win, Plech was awarded 2nd despite not actually finishing the race, while another Russian, Valery Gordeev, was awarded third place.
The result of the two points he gained for second place allowed Plech to finish a clear third in the championship. The ruling, with Khlynovski excluded, should have seen Collins 1st, Gordeev 2nd, and Plech scoring no points after failing to finish. This would have resulted in Plech only finishing the championship on 10 points and in a 5th place tie with Khlynovski. Had the Russian not been excluded and had been awarded the heat win as many, including World Champions Ivan Mauger and Ole Olsen, believe he should have been, he would have ended on 13 points. This would have put him in the run-off for the title with winner Jerzy Szczakiel (Poland) and defending champion Mauger.
