The 14-6 Riley had a 1,633 cc 6-cylinder OHV engine which produced 50 bhp (37 kW). The car could reach a top speed of 109 km/h. All four wheels were suspended with semi-elliptic springs.

In 1930, the Riley Stelvio appeared with the same engine and a slightly longer wheelbase. It reached 107 km/h, and the sedan received a bigger engine with a capacity of 1726 cc, just before the model was discontinued.

In 1931, the Alpine Riley appeared with the same chassis and the same engine as the Model 14-6. After 2 years this model was dropped.

The successor was the Riley 12/6 which had a slightly smaller engine.
