Bill Davis, an avid Harley rider and engineer from St. Louis, Missouri, designed the softail in the mid-1970s. His first design, which he worked on in 1974 and 1975, had a cantilever swingarm pivoted at the bottom and sprung at the top with the springs and shock absorber hidden under the seat. Davis then built a prototype based on his 1972 Super Glide. He patented the design and arranged to meet Willie G. Davidson August 1976. Davidson was impressed, but made no commitments, and six months later, said Harley-Davidson was interested but would not use the design at that time.
