The 1925 AJS Model E1 is one of the first V-twin motorcycles produced by the British brand, and was defined by features such as a hardtail rear suspension, a sprung rider seat and a sprung passenger seat, pull-back handlebars, laced wheels, a rigid front suspension, and a small headlight. At its heart lies an air-cooled, four-stroke, 799cc, V-Twin powerplant paired to a three-speed manual transmission, and can produce a claimed 8 horsepower.
