Harley Davidson FL 1200 Type 74 Knucklehead
1946 Harley-Davidson 1200cc
Knucklehead Type 74 In its 90 year history, Harley-Davidson could never have
been accused of being technically adventurous. But this conservative outlook has
saved the Milwaukee company from making disastrous mistakes. In the early
Twenties, Harley-Davidson became the world's biggest motorcycle manufacturer,
with an annual capacity of 35,000 machines.
Consistent Policy
Since 1909, the firm's hallmark has been the big vee-twin, a policy that has ensured the survival of Harley-Davidson when all the other American motorcycle manufacturers have fallen by the wayside. In 1936 the company introduced the valve-in-head 61 cubic inch. (100cc) Type EL, nicknamed "Knucklehead" because of the shape of its rockerbox castings. Conservative Specs
The Knucklehead boasted such features as a four-speed gearbox with hand change and food clutch, a double cradle frame and pressure lubrication. After the war, America (which had imported only a handful of European motorcycles before the war) discovered the charms of the light, fast British twins. In 1946, American built just 20,000 motorcycles-and imported 9,000, of which 8,000 were English! To respond to this new scenario, Harley offered the Type 74, a 1200cc derivative of the prewar Knucklehead, which saw the light of day in 1941. It remained in production only until 1948.
