His best season was in 1951 when he won the Dutch TT and finished the year second to Geoff Duke in the 350cc world championship.[6][7][8] Doran won two Grand Prix races during his career.
Doran had part of the Isle of Man TT course named after him. He was proud because, at the time of dedication, he was the only living recipient with a named section.[5] He crashed during a Thursday evening practice for the 1952 Isle of Man TT riding an AJS motorcycle resulting in a broken leg.[9] The accident occurred on the left-hand bend after Ballig Bridge and was renamed Doran's Bend.
In late 1952 at the London Motorcycle Show, Doran approached the Italian company Gilera for a works ride for the 1953 season. However, in a letter dated November 27, 1952 Gilera replied to the request stating the positions on their team were filled for the coming season so Doran started the 1953 season on his now obsolete AJS scoring three points paying finishes before the career ending crash at Rouen.
After retirement from racing in 1954 he opened a motorcycle business in Wellington, Shropshire, with former AJS race-chief Matt Wright,[10] selling new motorcycles collected from the Birmingham factories in a pick-up vehicle driven by Doran's wife Peggy, daughter of Herbert Ratcliffe,[5] whom he married in 1955.[11]Isetta and Messerschmittthree-wheelers were also collected from Luton airport.[5]
Partner Matt Wright retired in 1967, and with the demise of the British Motorcycle manufacturers, most notably BSA in 1971, Doran developed the business into a Yamaha, Suzuki and Lambretta dealership in addition to a FIAT car dealership, car repairs and petrol sales, with the later acquisition of two further nearby sites.[1][5]
Known physically by his jutting chin, Doran died of a heart attack[5] at his home, Carn Brea, Station Road, Admaston, near Wellington[12][13] in September 1973 aged 56.[14] After a funeral service at Wrockwardine Parish Church on 14 September 1973 he was cremated at Emstrey Crematorium, Shrewsbury.[13]
