Responding to demands from sidecar drivers for more power, FN introduced a new 748cc four – the Type 700 – for 1914. This new engine was a sidevalve of 'T'-head layout, with mechanically operated valves and a mechanical oil pump, which drove the three-speed gearbox via a steel, multi-plate clutch. Pedal starting was dispensed with on the Type 700, a kick-start mechanism being added at the engine's right-hand side. The Type 700 had not been in production long before the FN works was seized by the invading German Army in the autumn of 1914. The occupying Germans used the FN factory to manufacture ammunition while continuing production of the Type 700, which had a top speed of around 72km/h (45mph) and was widely used by despatch riders. The model remained in production up to 1923 when it was replaced by a new overhead-valve, chain-driven four. FN's new 748cc four featured an integral three-speed gearbox and electric lighting as standard although, bizarrely, the dynamo was an optional 'extra'! Despite this improved specification, sales were disappointingly sluggish and FN's long-running four was dropped from the range in 1926, thus closing the chapter on the world's first commercially successful four-cylinder motorcycle. Dating from the final year of production, this restored FN motorcycle combination previously formed part of the Spanish Pamplona Collection, sold by Bonhams in February 2010. The machine was last used a few months ago and is described as all original and in excellent working order. It is offered with a (copy) instruction manual and Belgian registration papers.

    En réponse aux demandes des utilisateurs de side-cars en faveur d'un supplément de puissance, FN introduisit une nouvelle quatre cylindres de 748 cm3 - le Type 700 – en 1914. Le nouveau moteur doté de soupapes latérales symétriques commandées et d'une pompe à huile mécanique entraînait une boîte à trois vitesses via un embrayage multidisque en acier. Le démarrage par pédalage fut remplacé sur le Type 700 par un mécanisme à kick ajouté sur le côté droit du moteur. La Type 700 n'était pas en production depuis longtemps quand l'armée allemande mit la main sur les usines FN à l'automne 1914. Les occupants convertirent l'usine à la fabrication de munitions tout en poursuivant la production du Type 700 qui atteignait 72 km/h et que les estafettes militaires utilisèrent en grand nombre.La modèle demeura en production jusqu'en 1923, date à laquelle il fit place à une nouvelle quatre-cylindres à soupapes en tête et transmission par chaîne. La nouvelle « quatre » 748 cm3 de FN bénéficiait d'une boîte intégrale à trois rapports et de l'éclairage électrique installé d'origine, mais, bizarrement, la dynamo était en option. Malgré ces spécifications supérieures, les ventes furent désespérément médiocres et la quatre-cylindres FN disparut du catalogue après une longue carrière en 1926, fermant ainsi le chapitre relatif à la première moto à quatre cylindres du monde ayant connu le succès commercial.

    Datant de la dernière année de production, cette FN restaurée faisait autrefois partie de la Pamplona Collection espagnole vendue chez Bonhams en février 2010. Cette machine qui a roulé il y a quelques mois, décrite comme étant toute d'origine et en excellent état de fonctionnement, est accompagnée de son manuel d'utilisation (en copie) et de ses papiers d'immatriculation en Belgique.
