Fx Series Introduction:
The FX platform was introduced in the early 1970s, offering a more versatile chassis than the traditional FL (Electra Glide) models. The FXS was a specific variant within this series.
Super Glide Concept:
The Super Glide was designed to combine the power of the Shovelhead engine with a lighter, more agile chassis compared to the larger touring bikes.
Production Era:
The FXS Super Glide was produced through the 1970s and early 1980s, with the 1977 model representing a key iteration.
