A softail-style cruiser motorcycle produced by Harley-Davidson
In Harley-Davidson motorcycles, the softail frame is designed to look like the hardtail bikes of the past, while still offering the comfort of rear suspension. The shock absorbers are positioned along the axis of the motorcycle, tucked away under the transmission. There are several Harley-Davidson models with the Softail frame, including the Softail Standard, Custom, Springer Softail, Heritage Softail, Heritage Springer, Night Train, Deluxe, Deuce, Fat Boy, the Dark Custom Cross Bones, and the Dark Custom Blackline.
