The AJS 16, 18, 20, 31, 31CS, and 31CSR motorcycles, produced in 1962, were a diverse range of machines catering to various needs and riding styles. The AJS 16 was a lightweight, entry-level motorcycle powered by a 197 cc single-cylinder engine, making it ideal for beginners or those seeking economical transportation. The AJS 18, with its 249 cc engine, offered a slightly more powerful experience, suitable for commuting and short trips. The AJS 20, however, was a different beast entirely, equipped with a 498 cc parallel-twin engine, providing ample power for longer journeys and even some light touring. The AJS 31, 31CS, and 31CSR models, all powered by a 498 cc engine, were designed for more serious riders. The 31 was a standard roadster, the 31CS featured a café racer design with clip-on handlebars and a streamlined fairing, and the 31CSR was a scrambler version optimized for off-road riding.

These AJS motorcycles, despite their diverse configurations, shared a common heritage of robust build quality and reliable performance. They were known for their simple yet effective design, featuring a traditional tubular steel frame, telescopic forks, and a swingarm rear suspension. The single-cylinder and parallel-twin engines were renowned for their durability and smooth operation, with a characteristic British "thump" that added to their charm. The AJS models of 1962, while no longer in active production, remain a testament to British motorcycle engineering and a cherished part of motorcycle history. For enthusiasts, collectors, and riders who appreciate the classic character of vintage motorcycles, these machines continue to attract attention and provide a unique experience on the road.
