Riding his 1939 Norton, he participated in several races in the immediate post-World War II period including the 1946
Cookstown 100 event where he recorded the fastest lap time of 76.60 mph and winning the 1947 500cc
Ulster Grand Prix race with an average speed of 91.25 mph (146 km/h) in a time of 2 hours 43 minutes 1 second, while setting a new lap record of 94.79 mph (151.17 km/h). Away from motorbikes, he also won the 1946 Circuit of Ireland Rally, in a 12/4 Riley Sprite. Bell also won the 1947 North West 200. Following his 1947 Isle of Man performance, Norton picked him up as a works rider for the following season. He did not finish in his TT Junior 350cc race, however, the next season he claimed first place in the 500cc
Senior TT race and third place in the 350cc Junior event. In
1949 he placed third and fourth in the TT as well as taking the North West 200 again. Norton introduced the
Featherbed frame in
1950 contributing to his
1950 first place in the 350cc Junior race and second place in the 500cc Senior race. Further placings in the 1950
Dutch TT and
Swiss Grand Prix ensured his position in the
1950 Grand Prix season with seventh and fourth place respectively in the 500cc and 350cc championship standings. Bell also claimed the North West 200 for a third time. 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. When Bandirola braked early for the La Source Hairpin, a collision occurred when the
AJS Porcupine motorcycle ridden by Graham hit the rear wheel of the motorcycle ridden by Bandirola. Although Graham was thrown clear, Bell hit the AJS Porcupine and machines collided at high speed with a timing-post at La Source Hairpin. Bell was unable to race again even though he survived serious injury. He died on 7 August 1972 at his home in
County Down. In 1996 the
Irish Post Office issued a set
postage stamps of notable Irish motorcyclists that included a stamp depicting Artie Bell. Also in 1996, the
Isle of Man Post Office issued a set of post stamps of Irish Isle of Man TT winners including Artie Bell's win during the 1950 Junior TT race. ==Motor-Cycle Grand Prix results==
