Despite the success of the 1906 thru 1927 FN shaft drive fours, FN began producing more conventional chain driven overhead valve four stroke single cylinder machines in the late 1920s
This 1947 model M13 has a side valve engine with wet sump lubrication but its most distinctive feature is its front fork
This trailing link design tensioned the horizontal springs when the wheel was pushed upward when riding forward like pulling a wheelbarrow rather than pushing it
This FN received a complete ground up restoration by Retrospeed in Belgium, Wisconsin and has been featured in Motorcycle Classics Magazine
