Historical Notes and Mythology

Debut (1990): Created by Willie G. Davidson and Louie Netz, the first version is known as the "Gray Ghost" for its silver livery and yellow outlines on the engine heads.
Origin of the Name: Although an urban legend links the name to the atomic bombs "Fat Man" and "Little Boy", the parent company has always denied it, stating that the name simply describes the massive and muscular look of the motorcycle.
Special Editions: In 2025 a limited 35th Anniversary Gray Ghost edition was launched (1,990 units worldwide) paying homage to the original 1990 color with modern technologies.
