Electra Glide Introduction:
The Electra Glide nameplate was introduced in 1965, with the 1960 model likely referring to a predecessor or a model that would evolve into the Electra Glide, such as the Duo-Glide or Hydra-Glide, which shared many of its core characteristics and powertrain.
Predecessor Models:
Panhead models (1948-1965) served as the foundation for the Electra Glide, with the Duo-Glide (1958-1962) being a direct precursor, featuring dual rear shock absorbers and the Panhead engine.
Manufacturing Era:
Panhead era (1948-1965) represents the technological baseline for this manual.
Key Innovations Of Era:
Introduction of dual rear shock absorbers (Duo-Glide), electric starter (later models).
