Charles Mortimer (born 14 April 1949) is an English former professional motorcycle short-circuit road racer and race-school instructor. He competed in the Grand Prix motorcycle road racing world championships from 1969 to 1979.[1] He remains the only competitor to have won FIM Grand Prix races in the 125, 250, 350, 500 and 750 world championship classes.[2]
Born in Shere, Surrey, UK, Mortimer is the son of Charles Mortimer Senior, a former motorcycle road racer and proprietor of the Charles Mortimer Race School based at Brands Hatch race circuit, Kent. The school was originally named in 1963 as the Beart-Mortimer racing school, with engine tuner Francis Beart being a partner to Mortimer Senior which ended in 1965 due to Beart's other business involvements.[3] From 1966 the venues included Cadwell Park, Silverstone and Mallory Park.[4] [5]
Mortimer began racing in 1965 on a Greeves Silverstone as used by the race school.[6] At 18 years of age in 1967, Mortimer was one of the school's instructors, with Paul Smart being another. Both were competitive riders sponsored by Charles Senior, riding from a stable of machines consisting of RDS Greeves 250s, a Bultaco 125 and an Aermacchi 350.[7] He competed for most of his career as a privateer riding Yamaha motorcycles. When Mortimer won the 1972 500cc Spanish Grand Prix on a Yamaha, it marked the first 500cc Grand Prix victory for the Japanese manufacturer.[2] He had his best Grand Prix season in 1973 when he finished second to Kent Andersson in the 125cc world championship.[1] Mortimer also competed successfully at the Isle of Man TT, with eight victories at the event.[8] [9] In 1976, he won the Macau Grand Prix.
In the 1970s Mortimer operated a race school and ran a business in Reading, Berkshire importing motorcycle parts .[10] [11] As of 2013 he is running a transportation company specialising in transportation of motorcycles.[6] His brother Robin Mortimer had a long career in motor sport. When he died in 2007, he was manager of RPM Motorsport with his son Alex as driver in GT class.[12]
