The Velocette KSS was a pre-war British sporting motorcycle, built from the mid-1920s through to the late 1930s.

It features a 348cc single-cylinder engine with an overhead camshaft driven by a shaft-and-bevel system, producing around 20–25 bhp. The design focused on smooth, precise running rather than outright power.

With a lightweight chassis and advanced engine layout for its time, it offered strong performance on UK roads and was popular in club-level competition, becoming one of the standout British singles of the period.
