Oldtimer motorcycles: 1902-1965.
Pictured here is factory literature from the FN 1902 up the FN M.60 of 1924. These are all the 1- and 4-cylinder owner and parts lists that I own.
The end of the shaft driven FN motorcycles came in 1924. The four-cylinder engine remained but the bike was chain driven. This was the M.50. The four cylinder engine was also abandoned afterwards as it was more economical to build single-cylinder motorcycles like the 350 OHV M.60 and the 500 OHV M.67. The M.67 came in A, B, C or D versions, this designation can be identified by the serial number. Please refer to the serial number data for more information.
In 1926 FN introduced an affordable motorcycle, The Sahara M.70, this model was very popular compared to the earlier and more expensive M.60 and M.67. The M.70 remained available for many years in different versions. It was finally replaced in 1936 by the M.71.
1934-35 saw the introduction on the powerful M.86. This model was soon used in racing with 500 and 600cc OHV engine configurations.
FN introduced the 2 stroke lightweight M 200 (2 gears) and M 250 (3 gears) during the great depression. These models were affordable and helped the company with sales in harsh times.
The M 11 (with 350 OHV, 500 or 600 SV engine) and the M 90 /91 (500 SV) were introduced in the latter part of the 1930s. The M.90/91 was a more powerful version of the M. 70 (350 SV).
FN's motorcycle department reacted to the military build-up of the 1930s with the introduction of the M.12SM in 1937. This model was powered by a two cylinder 1000cc. boxer engine. The M.12 was made available in a variety of configurations including various military TriCar configurations.
After the WW II FN introduced the type XIII followed in the 56s by the M22/175cc and M22/250cc. Toward the end they also had a range op moped. First with Royal - Nord engines and then with there own engine.
