The Matchless G9 Super Clubman and corresponding AJS Model 20 were launched at the Earls Court motorcycle show in late 1948. At first exclusively for export to the US, it was not until late in the summer of 1949 that Matchless first offered the G9 on the home market. From the beginning, it had a "Teledraulic" telescopic front fork, swinging arm rear suspension, dual seat, and "megaphone" silencers. The basic design changed little over the course of the next few years.
