Harley-Davidson, one of the most iconic motorcycle manufacturers, has a rich history spanning over a century. While the precise number of surviving early Harley-Davidson motorcycles is difficult to determine, here are some notable models that have survived from the early years:
Serial Number One (1903): This is the oldest known Harley-Davidson motorcycle in existence. It is a prototype built by William S. Harley and Arthur Davidson in a small shed in Milwaukee, Wisconsin. Serial Number One features a single-cylinder engine, pedal power, and a leather belt drive.
Silent Gray Fellow (1911): Also known as the Model 6A, this motorcycle was part of the first Harley-Davidson V-twin engine series. It earned its nickname due to its quiet operation compared to earlier models. The Silent Gray Fellow is highly sought after by collectors and enthusiasts.
Single Belt Drive (1912): In 1912, Harley-Davidson introduced the belt drive system, replacing the previous chain drive. This design improvement significantly reduced vibration and provided a smoother ride. Examples of Harley-Davidson motorcycles with belt drive from this era can still be found in private collections and museums.
Model J (1920s): The Model J was a popular motorcycle series produced by Harley-Davidson during the 1920s. These bikes featured a 1000cc V-twin engine, a three-speed transmission, and electric lighting. Some surviving examples of the Model J can still be seen today, showcasing the craftsmanship of that era.
Knucklehead (1936): The Knucklehead, introduced in 1936, was Harley-Davidson's first overhead valve V-twin engine. Its unique appearance, with valve covers resembling knuckles, gave it the name "Knucklehead." This model represented a significant engineering advancement for Harley-Davidson and is highly prized by collectors.
These are just a few examples of the oldest surviving Harley-Davidson motorcycles. It's worth noting that many early motorcycles have been preserved in private collections, museums, and by dedicated enthusiasts worldwide, ensuring the legacy of these historic machines.
