But by the time the market got behind the FXRs, its replacement, the FXD Dyna, was already in the works. In many ways, the Dyna was designed to be what the FXR was not. If the FXR wrapped its frame around components, the Dyna would revert to a backbone construction, harking back to the original FX look even at some cost in frame stiffness. If the soft rubber mounts of the FXR allowed almost an inch of engine movement, forcing gas tank and other components to be located with airy spacing, the Dyna would shorten that with two stiffer rubber mounts—even with some increase in the amount of vibration transmitted. If the FXR frame had too many joints and was expensive to build, the Dyna frame would be simpler, with a investment-cast steering head that plugged right into the backbone—even if that technique made it far more difficult for customizers to rake it out. But by the time the Dyna came out, the FXR was not a strange new addition to the Harley line; it was one of the mainstreams. And when it went away, it was missed.
