The John Hobbs Collection c.1906 FN 410cc Four Project Registration no. BX 3851 Frame no. 18728 Engine no. 49 •The world's first practical four-cylinder motorcycle •Offered for restoration •Offered with a V5C 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 and was first exhibited publicly at the 1905 Paris Cycle Show. Designed by Paul Kelecom, 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. This Lot consists of a frame, forks, wheels, handlebars, tank, an incomplete shaft drive, and an engine. Other parts include a saddle, three mudguards, inlet manifold/pipe; and rear hub covers. Offered with a V5C little else is known about this particular machine.
