John 'Mooneyes' Cooper had the given name of John Herbert Cooper. He started motorcycle sport local to Derbyshire by riding a rigid-framed 197cc James entering off-road trials in 1954 at age 16. He progressed to a plunger-sprung James track race bike tuned by Harry Lomas entering informal events organised by his local Derby club at Osmaston Manor. For 1958 Cooper had a different James powered by a tuned Triumph Tiger Cub engine, which he raced against Percy Tait who also had a Cub. Cooper had a long-standing association with motorcycle dealer Wraggs. By 1960 he was riding their BSA Gold Star for the 500cc class and later a 350cc Gold Star engined Norton. 1961 saw Wraggs providing him with 1960 350 and 500 Manx Nortons which he later purchased in 1964, selling them on in 1966. A trained mechanic, he preferred to work on his own bikes, excepting the engine preparation which was by respected tuner Francis Beart. Cooper first entered the TT races in 1964, scoring ninth-place in the Senior 500cc race, failing to finish in the other classes and again in the 1965 races when riding a 250cc Greeves with 350 and 500 Nortons. Cooper was famously known as 'Mooneyes'. He initially decorated his helmet with the initials 'J C' followed by a hand-drawn cartoon character "Jiminy Cricket", continuing the 'J C' theme. His helmet was rejected by race officials, so he painted a new helmet red but found it plain. Adding two stick-on giant 'eyes', a motoring gimmick of the 1960s, endured as his personal design throughout his career. Cooper's experience and successes continued throughout the 1960s becoming a rival to Derek Minter who retired from racing in 1967. Minter was known by his race successes as 'King of Brands', and Cooper as 'Master of Mallory'. A section of the Mallory Park, Leicestershire circuit has been renamed from Lake Esses to the John Cooper Esses in his honor. Cooper rode a variety of machinery during his race career, including a Kawasaki 250 cc twin in the 1967 Lightweight TT, Norton twins, Seeley AJS 350 cc and Seeley Matchless 500 cc, 250 cc and 350 cc Yamsels – Yamaha two-stroke engines fitted into Seeley frames, and in the 1970 Production 750 cc TT race on a works Honda CB750, finishing in ninth place, before being associated with the works BSA Rocket 3.
