Hydra-Glide
In 1949, a year after receiving the "Panhead" engine, the FL was given a new front suspension and a model name to go along with it. In honor of their first production motorcycle with hydraulically damped telescopic forks, the FL was officially called the Hydra-Glide. This name would change twice in the history of the basic large-framed FL bikes, each time signalling an improvement in the bike's technology. In addition, the Glide ending would be used on other models, based on both and FL and FX formats.
In 1952, the Hydra-Glide's transmission standard hand-shift/foot-clutch was joined by the optional foot-shift/hand-clutch. Although the original format continued to be offered as an option until 1978. 1952 was also the last year of the 61 cu in (1,000 cc) EL, making the FL the last remaining large-frame model.
Although the 1903 founding is now the basis for "Anniversary Models", Harley-Davidson's 50th Golden Anniversary was celebrated in 1954 with special paints and badges on the front fender. (1904 was the first year of production.)
A more highly tuned engine with high-compression heads, higher-lift cams, and polished ports, was offered with the FLH version of 1955. The FLH designation has continued up to the present.
