Very rare Belgian FN model M86 600cc OHV with hairpin springs delivered to the Belgian army. Of this model there are only about 30 delivered to the Belgian army. So far there are only 3 known motorcycles that still exist. Everything is different on this army motorcycle than the well known civilian sports version. Frame is different, front fork is wider to use the hubs of the FN 1000cc and both fuel tank and material box and many small parts are different from the civilian model.
