FN 1933 “ M 67 C” 496 cc OHV frame # 30064 engine # 523
At the end of 1923 FN marketed a 350 cc single cylinder ohv with unit construction engine and horizontally split crankcase.
This model, the M60, was the start of a successful new line of models in a period in which the heavy and expensive four cylinder was quickly loosing ground.
Two years later a bigger 500cc brother was brought out, the M 67 with bore and stroke dimensions of 85×87 mm.
In October 1927 the M 67 B was brought out, with a new type of frame and a bigger petrol tank.
In 1929 the M 67 “C” got enclosed pushrods and rocker gear.
The M67 was very successful in sporting events.
The Depression years were very hard for the factory: in 1932 the total production amounted to 3,263 machines, less than half of the production of 1931.
1933 was even worse with only 1,742 units produced.
Production of the M 67 ended in 1934 when its successor, the venerable M 86, was introduced.
The M 67 was with its 140 kilos a relatively light and agile machine with a top speed of about 110 kms.
This machine is equipped with Bosch electrics – as usual with FN- and French Gurtner carburettor and comes complete with O.S. speedometer.
It has been restored with an excellent eye for detail: note the spacers for the operating cables in front of the handlebars.
