While the reprint of the original 108 page AMC workshop manual states that it is appropriate for the 1957-1964 models, it actually covers the entire line of AJS and Matchless 250cc to 650cc Lightweight and Heavyweight singles and 500cc to 650cc twins manufactured by AMC through 1966 (see below). Please note that it does not include the 750cc AMC G15/45 (1962-63) or the later Norton/AJS/ Matchless G15 hybrids. Owners of these 750cc hybrids are directed to the 'Norton 1966-70 Lightweight & Heavyweight Twins' workshop manual, ISBN 9781588502421 as it includes significant maintenance and repair information on those models.
While the single cylinder machines are always considered the backbone of AMC's post-war production, in 1948 they introduced a 500cc twin cylinder, the AJS model 20 and Matchless G9. However, it was 1957 before that singular model was joined by a number of additional 500cc, 600cc and 650cc twins. In 1958 they also added two 'lightweight' singles to their well respected line of 'heavyweight' singles. Unfortunately, by the mid 1960's, along with most British motorcycle manufacturers, AMC was struggling to compete with the flood of Japanese imports and by 1966, the AMC conglomerate had collapsed. While the reason is mired in mergers, finances, consolidation, politics and worker unrest, both the AJS and Matchless name continued onward, under license, until early 1970, at which point both marques were history.
