Harley-Davidson introduced the FXR chassis in 1982 as a stiffer, better-handling platform.
The FXR was developed to improve the rigidity and riding behavior of Harley-Davidson’s large motorcycles. Its frame used more sophisticated construction than the company’s traditional touring and cruiser frames, and the engine was rubber-mounted to reduce vibration reaching the rider.
The first FXR models included the Super Glide II and related variants. The platform combined a five-speed transmission with a chassis intended to provide more controlled handling than many earlier large Harley-Davidson motorcycles.
The FXR name is often confused with Dyna, another Harley-Davidson chassis family introduced later. Although the Dyna eventually occupied a similar market position and replaced the FXR in the lineup for a period, the two platforms were distinct designs.
