Aside from the change in displacement, everything else remained similar to the 1905 model.

However, the 1906 model featured the same single-speed transmission with pedal start and coaster brakes as the 1905 mode. Through this, the engine output jumped from 3.45hp to 4.5hp. In 1906, the displacement was increased from 362cc to 410cc. Want to know why? The mass production of cars for the public actually started later in 1908 which made motorcycles the prime mean of motorized personal transportation.ĭid you know, the FN motorcycles also held the world record for the World’s fastest production motorcycle from 1911-1912. The production only ran for 20 years, from 1905-1923, however, the FN motorcycles were a massive commercial success. Later with time, Fabrique Nationale designed and developed various different upgraded models of the FN Four which we will look into detail later. The FN Four was developed in 1904 and launched later in 1905 at the Paris Motorcycle Show. Note, there have been numerous motorcycles before the FN Four was developed but they mostly used a single cylinder or horizontally opposed “boxer” twin/four engine.

However, the first production inline-four motorcycle was manufactured in the earlier 1900s.ġ905 FN four is the world’s first production inline-4 motorcycle manufactured by Belgian Firearm manufacturer, FN (Fabrique Nationale) in Liége, Belgium. Ever wondered how inline-four motorcycles came to life? well, it all started way back in the late 1890s.
