Under AMC the AJS badge may have been put on the "bread and butter" Matchless motorcycles, but the Colliers were mindful of the AJS racing heritage, and used the name on some innovative racing machinery. These racing bikes kept the AJS name alive. | Under AMC the AJS badge may have been put on the "bread and butter" Matchless motorcycles, but the Colliers were mindful of the AJS racing heritage, and used the name on some innovative racing machinery.

In 1935, at the Olympia Show, an air cooled SOHC AJS 50° V4 was shown, a fully equipped road going version, which did not make it into production. In 1936 Harold Daniell rode a supercharged race version in the Isle of Man Senior TT, but despite its high top speed, it lacked acceleration. | In 1935, at the Olympia Show, an air cooled [[SOHC]] AJS 50° V4 was shown, a fully equipped road going version, which did not make it into production.

In 1939 the dry sump V4 was the first bike to lap the Ulster Grand Prix course at over 100 mph (160 km/h). It weighed 405 lb (184 kg). and its top speed was 135 mph (217 km/h). Then World War II intervened. | ||
At the end of the 40s and start of the 50s, the AJS Porcupine, a 500 cc forward facing parallel twin, and the AJS 7R (32 bhp, 350 cc OHC single) were being raced alongside their AMC stablemates the Matchless G50 (effectively a 500 cc 7R) and by 1951, the Matchless G45 (a 500 cc vertical twin). The AJS Porcupine had been designed for supercharging, before the rules changed banning supercharged racing motorcycles, but even so, Les Graham won the 1949 World Championship on an unsupercharged AJS E90 500 cc Porcupine. | At the end of the 40s and start of the 50s, the AJS Porcupine, a 500 cc forward facing parallel twin, and the AJS 7R (32 bhp, 350 cc OHC single) were being raced alongside their AMC stablemates the Matchless G50 (effectively a 500 cc 7R) and by 1951, the Matchless G45 (a 500 cc vertical twin).
