• The world's first practical four-cylinder motorcycle
• Offered for restoration
• Unregistered

Like BSA, La Fabrique Nationale d'Armes de Guerre ('FN' for short) began as a munitions manufacturer, turning to the production of motorcycles in 1900. Today the Belgian company is best remembered for its sensational four-cylinder models, the first of which appeared in 1904. The FN was the world's first practical four-cylinder motorcycle, its smooth, almost vibration-free operation setting it apart from rival singles and v-twins. Advanced for its day, the 362cc air-cooled four featured 'atmospheric' inlet and mechanical (side) exhaust valves; a robust five-bearing crankshaft; individual crankcase oil wells for the connecting rods; and reliable Bosch magneto ignition. Shaft final drive was another innovation. Supported on ball bearings, the driveshaft ran inside the right-hand frame member to a bevel gear on the rear axle. At first there was no clutch, the direct-drive machine being started by pedalling away until the engine fired. Two brakes (drum and rim-type) both operated on the rear wheel. The engine was enlarged to 410cc in 1906 and 498cc in 1910. In 1911 the factory introduced its own two-speed transmission, similar to that already offered by Horstmann in Britain, which was contained within the drive-shaft housing.

An earlier restoration (date unknown), this FN Four features a highly polished tank, while some of the plated parts are chrome rather than nickel. A kickstart is fitted, but one grip and its control are missing. There are no documents with this Lot. Requiring restoration to a greater or lesser extent, prospective bidders must satisfy themselves as to the condition, completeness, correctness, date and suitability of the machine's component parts prior to bidding.
