This 1955 AJS Model 20 is powered by a 498cc parallel-twin and utilizes a Teledraulic fork and rear swing arm. The longterm previous owner reportedly purchased the bike at the age of 16 in Thailand, and eventually relocated it to the US. A refurbishment was performed in the early 2000s, and the seller acquired the bike about three years ago. Within the past two months, a new battery and tires have been installed. This Model 20 is now being offered with a clear Mississippi title in the seller’s name. Associated Motorcycles Limited (AMC) released the AJS Model 20, along with its brand-engineered counterpart the Matchless G9, in 1949. The Model 20 received a chrome fuel tank with blue, black, and gold accents, while multiple components were carried over from AMC’s single cylinder line-up. Some signs of age are present in the brightwork, rubber, and black finish. Original components such as tank badges, jampot rear shocks, and rear-mounted tire pump have been retained. Braking is managed by 7″ drums in the front and rear, and a new set of Avon tires have been installed within the past two months. A 120 mph Smith speedometer is housed in the headlight shell and currently shows 714 miles. Actual mileage is unknown. The air-cooled parallel-twin displaces 498cc and uses overhead valves, an equal-length twin exhaust, and single Amal carburetor. Individual aluminum cylinder heads are utilized with a cast iron cylinder, and the pistons meet the three-bearing crank with a pair of connecting rods made from Hiduminium, an aluminum alloy developed by Rolls Royce. Charging for the 6-volt electric system is managed by a front-mount dynamo, while the ignition system utilizes a magneto mounted behind the cylinders. Behind the pressed steel cover is a chain drive primary and wet clutch, which sends power to the Burman four-speed gearbox. The seller recently cleaned the fuel tank and carburetor and performed a valve adjustment. A few small oil leaks are present.
