Arthur James Bell (6 September 1914 – 7 August 1972) was a British (Northern Irish) motorcycle road racer who became known for his short post-World War II Isle of Man TT career that came to notice with his second-place finish in the 1947 Isle of Man TT on a second-hand 500cc Norton he bought himself on which he led for three of the seven laps.

[1] Bell began motorcycling as a teenager despite the opposition of his father, who at one time forced him to get rid of his Sunbeam motorcycle, but by 1938 Bell prevailed and rode in minor events progressing to a second-place finish in the North West 200 an event that still takes place in Northern Ireland.

Unfortunately, his promising racing career came to an end following a high-speed crash during the 1950 season at La Source Hairpin during the 1950 Belgian Grand Prix at the extremely fast Spa-Francorchamps circuit.

The accident occurred during the 500cc race when the leader Carlo Bandirola was being followed by Les Graham and Bell.

Although Graham was thrown clear, Bell hit the AJS Porcupine and machines collided at high speed with a timing-post at La Source Hairpin.
