1931: MATCHLESS SILVER HAWK:
Prior to World War 2, Matchless manufactured engines for various
Companies including Brough Superior, Calthorpe and Morgan for their three wheel
cars. The Silver Hawk was manufactured in 1930 and the design was very advanced
for the era, features included a narrow angle V-four over head cam engine. The
motorcycle was powered by a 600cc V-four gear driven OHC engine driving through
a four speed transmission.
Of particular note are the very neat exhaust headers, single
carburettor for ease of tuning, a surprisingly simple intake air filter housing,
the neat gear drive to the OHC head, the protected distributor behind the engine
block, the horizontally split crankcase and the generous size valve covers for
maintenance.
