The Riley Imp was in production for only a short period of time, with a total of just 75 examples being made. Though few in numbers, they did earn a reputation for their performance in road races, rallies, trials, and speed competitions. The Imps featured dual carburetor performance engines and Riley’s excellent ‘Silent Third’ manual transmission, though many were specified with optional Wilson pre-selector gearboxes.
The Riley Imp was given Riley-built steering, cable-operated brakes, and a 1.1L four-cylinder engine that offered 50 horsepower.
