Harley Davidson Softail

Bill Davis, an avid Harley rider and engineer from St. Louis, Mo. 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. Upon working out his design, Davis built a prototype based on his 1972 Super Glide. Davis patented his design and contacted Willie G. Davidson, arranging a meeting in August 1976. Davidson was impressed, but made no commitments. Davidson replied six months later, stating that the company would not be able to use the design at the time but was still interested in it.

Davis continued to develop the design, switching the pivot and the springing points around so that the springs and shock absorber were under the frame and the pivot point was at the top of the triangular swingarm. This allowed the traditional Harley-Davidson oil tank to be placed under the seat. Davis attempted to produce the new design independently as the Road Worx Sub-Shock, but the partnership he had put together for this purpose collapsed. Harley-Davidson executive Jeffrey Bleustein contacted Davis shortly afterward and began negotiations to buy Davis's design. Davis sold his patents, prototype, and tooling to Harley-Davidson in January 1982. After further testing and development, Davis's design was introduced in June 1983 as the 1984 Harley-Davidson FXST Softail.
