K
K: The first new model received the letter "K", according to some sources, was the letter for "Kamshaft". They used very briefly the old name "Veloce", which was used up to the First World War. The Goodman brothers felt it appropriate to return to the old name, but the dealers do not. Velocette, with its two strokes built up a good name, and that name should therefore also be retained, they argued. Whether there was really K with "Veloce" on the tank is not certain; in any case name disappeared quickly.
The brothers did nothing in half measures. The Model K had a thoroughly modern engine with an overhead camshaft. The structure of the rest of the motorcycle was still quite conventional. It had an open flat frame with the engine as a load-bearing part, a parallellogram dork with friction dampers and no rear suspension. It was three speed manual.
KT: In 1925 already a second model appeared, which was not much different from the first. This model KT (Touring) had shields to protect the legs of the rider from the elements. Both models went out of production in 1927.
Velocette KS, KE, KES, KN, KNS
KS: In 1927, the KS came out, a KSS with the normal engine with low compression ratio.
KE and KES: In 1928 followed two "economy" models, KE (Economy) and KES (Economy Sport).
KN and KNS: In 1929, they were followed by two similar, inexpensive models, KN (Normal) and KNS (Normal Sport). These models used a modified big-end connecting rod bearing and had a saddle tank. They also disappeared after one year from the scene.
