Jon Ekerold
Jonathan "Jon" Ekerold is a South African former professional Grand Prix motorcycle road racer.
Born in Johannesburg, South Africa, Ekerold is one of the few racers in the modern era to have won a world championship as a privateer without the benefit of a motorcycle manufacturer's support when he defeated Kawasaki factory racing team rider Anton Mang for the 1980 350cc Grand Prix road racing world championship. Ekerold rode a self-modified Yamaha TZ350 engine in a Bimota chassis during his championship season. He also won the Ulster Grand Prix once and finished second at the Isle of Man TT twice.| Position | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
