Historical Notes and Mythology

The Debut (1990): Created by Willie G. Davidson and Louie Netz, the first version is known as the 'Gray Ghost' for its silver livery and the yellow accents on the cylinder heads.
The 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 bulky and "muscular" appearance of the motorcycle.
Special Editions: In 2025, a limited 35th Anniversary Gray Ghost was launched (1,990 units worldwide), paying homage to the original 1990 color scheme with modern technologies.
