The AJS 16M, 16MS, 16MC, 16MCS, 18, 18S, 18C, and 18CS motorcycles were a series of popular British machines produced by AJS Motorcycles from 1951 onward. These models represented a significant shift for AJS, moving away from their traditional overhead valve engine designs towards the more modern overhead camshaft (OHC) configuration. The 16M and 18 models were equipped with a single-cylinder, air-cooled 16 or 18-horsepower engine, respectively, while the "S" models (16MS and 18S) offered a more sporting focus with a higher compression ratio and a higher top speed. The "C" models (16MC and 18C) were designed for touring and featured a larger fuel tank, while the "CS" models combined the sportiness of the "S" models with the touring features of the "C" models. These motorcycles were renowned for their reliable performance, ease of maintenance, and stylish design, featuring a classic British motorcycle aesthetic with a robust tubular frame and a distinctive chrome-plated tank. These AJS models were highly successful in the 1950s and 1960s, capturing a significant share of the motorcycle market in both the UK and overseas. They were popular among both commuters and enthusiasts, appreciated for their versatility and affordability. The 16M and 18 models, with their simplicity and reliability, were particularly popular with novice riders, while the "S" and "CS" models offered a more spirited experience for the more experienced rider. Despite their success, the AJS brand faced challenges in the late 1960s and early 1970s due to increased competition from Japanese manufacturers. While the AJS 16M, 16MS, 16MC, 16MCS, 18, 18S, 18C, and 18CS models were eventually discontinued, they remain highly sought after by collectors and enthusiasts today, representing a key chapter in the history of British motorcycle manufacturing.
