William Raymond Amm (10 December 1927 – 11 April 1955) was a Rhodesian professional Grand Prix motorcycle road racer.
The purchase of a brand new Norton motorcycle allowed Amm to enter the prestigious 1949 Port Elizabeth 200 Motor-Cycle Race in South Africa and despite breaking the lap-record he finished in 17th place when the clutch started to slip.
Again entering the 1950 Port Elizabeth 200, Amm finished in 1st place for the 500 cc race and set a new lap record of 95.86 mph.
To practice on short circuits before the Manx Nortons where delivered, a 'hack' 7R AJS motorcycle was purchased and Ray Amm won the 350 cc class at a Peveril M.C.
Also at Montlhéry in November 1953, Amm shared a streamlined Norton Sidecar outfit with Eric Oliver to set further speed records.
The 1954 Senior TT race was delayed due to weather conditions and reduced visibility on the Mountain Section of the course.
[6] Further heavy rain and low cloud on the Mountain Section reduced speed further and on lap 2 and Amm used "feet-down"[7] tactics on the slower corners.
The next event after the 1954 Isle of Man TT Races was the Ulster Grand Prix held at the Dundrod Circuit in Northern Ireland.
[2] Despite many offers Amm finally moved from the works Norton motorcycles to the factory MV Agusta racing team.
Riding a 350cc four-cylinder MV Agusta in the Coppa d'Oro Shell Race, Amm lost control at the Rivazza Corner as he pursued Kavanagh and crashed in slippery conditions and died of his injuries on the way to hospital.
