The 1926 A.B.C. motorcycle was made in Great Britain. It featured an air-cooled, horizontally opposed twin four stroke engine. The ignition was by magneto. The engine displacement was 398cc. Fuel was supplied via a single carburetor. Getting the power to the ground was by a four speed transmission that was hand shifted. The suspension featured front and rear leaf springs that were 1/4 elliptical. Drum brakes were on both the front and rear. The motorcycle weighed in at 275 pounds. Top speed for the bike was 50 m.p.h.

According to the museum's fact sheet "When the prototypes of the ABC appeared in 1919 they were some of the most advanced specifications of any motorcycle up to that date. Front and rear suspension, drum brakes, a four speed transmission, multi-plate clutch and tubular cradle frame to name a few. In many ways the ABC was a forerunner of the BMW flat twin that appeared in 1923. Originally made in England by the Sopwith Aircraft Company, these machines were also made under license in France by aircraft engine makers Gnome et Rhone between 1920 and 1924."
