Ángel Nieto Roldán was a Spanish professional Grand Prix motorcycle racer. He was one of the most accomplished motorcycle racers in the history of the sport, winning 13 World Championships and 90 Grand Prix victories in a racing career that spanned twenty-three years from 1964 to 1986, mainly engaged in 50cc, 80cc and 125cc respectively. His total of 90 Grand Prix victories ranks him third only to the 122 by Giacomo Agostini, and the 115 for Valentino Rossi. In 2011, Nieto was named an FIM Legend for his motorcycling achievements.

Barry Steven Frank Sheene was a British professional motorcycle racer and television sports presenter. He competed in Grand Prix motorcycle racing between 1971 and 1984, most prominently as a member of the Suzuki factory racing team where he won two consecutive 500cc World Championships in 1976 and 1977. Sheene's 1977 title remained as Britain's last solo motorcycle world championship until Danny Kent won the 2015 Moto3 championship. However, Sheene is still the last British champion in the premier class.
