Riley RMF Saloon LHD


Herman Deroost


Riley introduced an entirely new post-war model in September 1945. The engine was not much different from that of the pre-war 1½-Litre unit giving 54 bhp and a top speed of 75 mph. The new chassis featured Torsionic IFS with torsion bars. Rear suspension was by semi elliptics with a torque tube axle, and brakes were hydro mechanical. The body, too, was of an entirely new design. Cubic capacity of the engine was 1496 cc. Wheelbase was 9 ft 4½ in.

And then the RMF came. Where the ‘B kept the same basic look as the ‘A, but had a longer wheelbase and bonnet and in 1946, 90bhp was available, eventually this went up to 100bhp by 1948. By happy coincidence, this also brought top speed up to 100mph as well. A total of 1,050 models were produced after introduction in 1952. Replacing the large RMB limousine in 1952, the Riley RMF was once again powered by the upgraded 2.5 L ‘Big Four’ engine and also shared the mechanical updates from the RME model. 1952’s RMF was an almost identical-looking replacement with improved suspension, hydraulic brakes in place of the previous hydromechanical ones and a larger, curved rear screen unfortunately only in production for 20 months. Manufacture continued until 1953 the RMF was the first to cease production as the 2½litre car gave way to Gerald Palmer’s Riley RMH Pathfinder in 1953.

Numerical prefix were added to the diamond bulkhead plate for RMs as in pre war cars until 1952 when it stopped and can be checked via the chassis number held by the club
