Engine no. M51/18S 17026
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 1950, models so-equipped being suffixed S. there are no documents with this incomplete AJS Model 18S, which is offered for restoration and sold strictly as viewed. No reserve.
- The engine number is 51/18S 17026.
