The Nine Brooklands was a car made by Riley between 1928 and 1932. Approximately 115 cars were built.
The Riley Nine engine was introduced in 1926 and it was only a matter of time until someone tuned it to make a car capable of lapping Brooklands at speed and getting multiple records under its belt.
The engine had two camshafts mounted high in the block, one was for inlet and the other was for outlet gases. A plunger type lubrication pump supplied oil at full pressure directly to the main bearings. The helical timing gears were at the front of the crankcase and the magneto was driven by a skew gear driven by the inlet camshaft.
The engine was connected to a four speed gearbox by a single plate clutch. The engine produced 50bhp and took the car up to 80mph (129kmh).
The chassis was 8ft long and had semi-elliptical spings all round. The brakes were cable operated and the car weighed 1100lb (488kg).
The works cars managed to win class races at the Brooklands Six Hour race and the Twelve Hour race at Le Mans.
The cars cost £395 in 1928 and £420 in 1931.
