The AJS 500cc Model 18 and AJS Model 18S are 500 cc British motorcycles almost identical to the Matchless G80 and both were produced in the same Associated Motor Cycles (AMC) London factory from 1945 to 1966. These bikes represent the end of the era of big British singles, as when AMC merged with Norton production concentrated on twins.
