Associated Motor Cycles announced its post-war range of AJS and Matchless 'heavyweight' singles in June 1945. Coded Model 18 and G80 respectively, the two 500cc models shared the same 93mm stroke as their 350cc brethren, coupled to an 82.5mm bore. Housed in a rigid frame with Teledraulic front fork, the rugged overhead-valve engine drove via a four-speed gearbox. Hairpin valve springs were adopted for 1949 and a swinging-arm frame introduced, the latter initially for export only but available in the UK from 1949, models so-equipped being suffixed 'S'. This 1950 AJS Model 18 has been fitted with an earlier (1946) engine. Purchased from Andy Tiernan Classics in 2016 (invoice on file), the machine has been totally restored by the Museum, as commemorated by the attached silver plaque. The machine's mechanical condition is not known; accordingly, prospective purchasers must satisfy themselves with regard to its condition, completeness, correctness, or otherwise prior to bidding.
