Registration no. OTU 190
Frame no. 82264
Engine no. 52/18S 20587
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 ruggedly built 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, models so-equipped being suffixed 'S'. Cleverly, AMC had devised this frame by the simple expedient of producing a new suspension-carrying rear sub-frame that bolted on in place of the old rigid back end. Thus it proved a relatively simple matter for owners of older rigid models to update them. Acquired in the mid/late 1970s, this dismantled Model 18S is offered for restoration and sold strictly as viewed. Accompanying paperwork consists of an old-style continuation logbook and V5/V5C registration documents. No reserve.
