Riley RM Roadster


Riley RM Roadster

It might look like the definition of an antique car, but under the skin the Riley RM Roadster was an advanced machine. Built to traditional methods with a separate chassis and ash-frame bodywork, the RM was Riley's first post-war car, and although the construction might have been old-fashioned, the engine and suspension certainly weren't. Power came from a revvy 1.5-liter twin cam unit that gave it a surprising turn of speed, while a fluent gearchange and hydraulic brakes meant driving quickly was also safe. At the rear, the car had semi-elliptic leaf springs, while independent torsion bars at the front meant it had good roadholding. The RM was a touring car in the most traditional British style, and in drophead form was rightly considered very desirable. However it was not a great export success and as a result the Riley RM series is much prized today.
