On Harley-Davidson motorcycles, FXR and FXD are model designations that represent different motorcycle families or series. Here's what they stand for:
FXR: FXR stands for "Factory Experimental Racing." The FXR series was introduced by Harley-Davidson in the early 1980s and was known for its frame design and handling characteristics. The FXR models featured rubber-mounted engines and a frame that provided improved stability and handling compared to previous Harley-Davidson models. The FXR series was popular among riders who preferred a more performance-oriented Harley-Davidson motorcycle.
FXD: FXD stands for "Super Glide." The FXD series is a part of Harley-Davidson's Dyna family of motorcycles. The Super Glide models within the Dyna family typically have a traditional cruiser-style appearance, with a blend of classic and modern styling elements. The FXD models are known for their balance of comfort and performance, making them popular among riders looking for a versatile Harley-Davidson motorcycle.
It's important to note that the model designations and naming conventions used by Harley-Davidson have evolved over time, and new models or series may have different designations. It's always a good idea to refer to the specific year and model of a Harley-Davidson motorcycle to get accurate information about its features and specifications.
