The Velocette KTT is a racing British motorcycle made by Veloce Ltd. The most significant variant of the Model K series of overhead camshaft Velocette motorcycles, the TT designation indicated the machine was intended for racing, and was an early example of a 'production racer' (although KTTs could be ordered as road-legal machines). The Velocette KTT was notable for having the first positive-stop foot gear change on a motorcycle, and one of the first with a swingarm rear suspension using separate sprung suspension units, although the Danish Nimbus pioneered this arrangement in 1919. The foot shift innovation significant improvement for racing, and quickly replaced the hand gear change lever, and became the standard for almost all motorcycles to this day. Veloce's swingarm suspension also had profound and lasting effects on the motorcycle industry, and remains the standard for motorcycle rear suspension to this day.
