1952 Model K

The 1952 Model K can be considered the grand-daddy of the modern day Sportster. The Model K was developed with a revised flat-head engine and a new four-speed transmission contained in the same castings that would eventually be used for the Sportster. There were many other design cues and features, such as the gas tank, fenders and frame, that would also be utilized by the Sportster, which was introduced in 1957.
