FN  1937    350 cc side valve  M 71   frame # 40794  engine # 18791

At the end of 1923 FN marketed a 350 cc  single cylinder ohv with unit construction engine.
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. 
Shortly after that four cylinder production was stopped altogether with FN.
The ohv singles were very successful, but the factory realised they were mainly appealing to  the sporty type of rider so it was decided to produce a side valve unit construction model as a utilitarian type of machine .
The model M70 had bore/stroke dimensions of 74x80.5 mm , unit construction engine and 3 speed gearbox.
The external flywheel of the early models was coloured red, hence the model’s nickname of           “ Moulin Rouge”.
To prove the model’s reliability   two French army officers and a Belgian mechanic crossed the Sahara desert with M 70s in April, May and June 1927.
They covered 6300 km of desert without  the machines failing them.
A heroic performance, that brought much publicity to the factory and coined the name “ Sahara” for the brave little machine.
The Sahara was a very successful machine: it was an easy starter, its reliability was high and it had a remarkable top speed of more than 90 km/ hour.
In 1936 the new M 71 was brought out. At first sight this new model  could be  seen as a make-over of the ubiquitous “Sahara”,  but appearances are deceptive here.
The engine was indeed  of the “Sahara” type, but this reliable and economical engine was built in  a new frame, an adapted  version of the 200 cc lightweight two stroke  frame. 
This combination resulted  in an ultra light motorcycle  that weighed less than 105 kilograms , had snappy acceleration and  remarkably good road holding and manoeuvrability. 
The M  71 could easily attain 100 km/h and  was  relatively cheap to buy.

The model  was available in “Touring Standard” and “Touring Luxe”. 
The latter had chromium petrol tank and exhaust damper and was fitted with more substantial tyres. This good-looking  “Touring Luxe” is a  older restoration and is equipped with Bosch electrics
