The Harley Davidson Super Glide is a motorcycle model made by the Harley Davidson Motor Company. Reputed to be the first factory custom motorcycle, it originated Harley's FX series of motorcycles by mating Harley Davidson Sportster components, most notably the front end, with the chassis of their larger big twin motorcycles. The current Super Glide model is now based on the Dyna Glide chassis which offers a wider variety of front ends and trim levels, and continues to fill the intermediate niche between the smallest and largest Harley models.
1971 FX Super Glide
From 1934 to 1970, with the exception of the Servi-Car, there have been two distinct lines of V-Twin Harley-Davidson motorcycles, the small twins and the big twins. However, individual bikers would sometimes customize bikes by changing parts around or cutting and rewelding frames and other components to suit their tastes.
The production FX Super Glide was released in 1971 to a lukewarm reception. Particularly not well received was the "boattail", which also proved to be unpopular on the Sportsters that had it. Sales of both models improved when less radical rear styling was made available.
In 1974, the FX was joined by the FXE, a version of the Super Glide with an electric starter. Both versions also got an exclusive one-piece tank instead of the Fat Bob tank used by the FL.
