Manufacturer: Gnome Rhone Model: D 'Grand Sport' Year: 1923 Displacement: 499cc Engine type: 4-stroke / sv Cylinders: 1 Bore/Stroke: 85x88mm Top speed: 100km/h Frame number: 7591 Engine number: 8003 One of the most famous aero engine manufacturers of WWI, Gnome et Rhône introduced its first motorcycle in 1919, building the Granville Bradshaw-designed ABC under licence. Previously rivals, the two firms had joined forces in 1914 and then in January 1915 Gnome took over Le Rhône, forming Société des Moteurs Gnome et Rhône. The diversification into motorcycle production had been prompted by the sudden decline in the demand for the company’s aeronautical products after WWI. Proprietary engines were used at first and then in 1923 the firm introduced single-cylinder power units of its own manufacture, pioneering the use of unitary construction for engine/gearbox. This 1923 machine has 500cc Gnome Rhone engine with outside flywheel, Gnome Rhone carburettor, pillion seat and a horn. Gnome Rhone used for this models a Marelli magneto and a Burman licence gearbox. This bike bears its first paint. For more details visit our website:
