1953 AJS MODEL 18 BACKGROUND
Since AMC owned both brands, the AJS Model 18 is almost mechanically identical to the Matchless G80. Besides styling, the only real difference between the two is that AJS mounted it’s magneto in front of the cylinder, and Matchless mounted theirs behind. Both were produced from 1945 through 1966.
