German B.A.M Version
and the Belgium model 200cc
version contains Villiers engine, with double exhaust cylinder and a separated
Alboin 3 gears gearbox , also its own Villiers carburetor and
ignition on a flywheel.
Here in "PDF" form the whole German article about the FN m200.
Belgium Version contains a “Block engine = all components in one such as
sprockets/ crankshaft and more in one” see picture from an open m 250 3 speed engine.
Belgium version has a Gurtner type “D” carburetor and the 200 cc has a Bosch
but the 3 speed 200 and 250 has a
Bosch magneto/battery coil
Note that the 200 cc and the 250 cc 3 speed model has only a external flywheel like
the m 71.
Even in the book “Quand la FN avait 2 roues” is not spoken about that model
from the German Range of FN’s but called B.A.M = Berliner (offices) Aacher (building FN's)
own a lot of German manuals but there is not often spoken about the 2 stroke
with English engine.
Most BAM’s are regular FN’s( even build in Herstal transported to Aachen approx
50 km from Herstal) with small changed details such as logo's at the tank
other steering handlebar and speedo meter and.....
Even more I never saw a German BAM 2 stroke at any kind of jumble/rally, I think
there will be probably one in live somewhere in Germany or?.
us hope we got the luck to see or meet ounce a running bike as the brother of
the Belgium model with his small block engine what is a other story to tell.
greetings Jacques owner of a m 250 3 speed 1937.
