The Harley-Davidson softail frame is designed to look like the rigid frame bikes of the past, while still having the comfort of rear suspension. The shock absorbers are positioned along the axis of the motorcycle, tucked under the transmission on models from 1984 to 2017 and under the seat on 2018 models. Bill Davis, an avid Harley rider and engineer from St. Louis, Missouri, designed the softail in the mid-1970s. After testing and development, Davis's design was introduced in June 1983 as the 1984 Harley-Davidson FXST Softail.
The WIL-D Betty adopts the purist frame shape of the soft-tail models. With its squat and purified design language, the motorbike has a very powerful appearance. The WIL-D Betty.
