The AJS Model 18CS was an evolution of the Model 18 – a bike that can trace its roots back to the G3L, an ex-military bike that was sold off in surplus once the war had ended. The C stood for Competition (as a scrambler bike), and the S stood for the fact that it had a suspension as opposed to a rigid rear frame.

Built for 15 years, the 18CS featured a 497cc single that produced 32 horsepower, which helped the bike attained a top speed of 81 miles per hour. Wet weight was 375 pounds, and the original MSRP was $425 – just over a dollar per pound!
