Harley-Davidson is an American motorcycle manufacturer that was founded in Milwaukee, Wisconsin. The Harley-Davidson Motor Company began production with the "Silent Gray Fellow" in 1904. Over the next 14 years, design modifications increased engine capacity, incorporated an inlet-over-exhaust valve gear and strengthened the frame.

Function

General transportation.

Technical

The 1912 models ushered in a new frame that moved away from the bicycle look. The top rail now sloped downward at the rear and permitted a lower saddle. Harley-Davidson made its motorcycles more comfortable in 1912 by offereing seat posts (a patented "Ful-Flotein" device that cushioned the seat with a spring inside the seat tube), The pedal cranks were mounted on a hub that had eccentric end pieces holding the hub of the frame. This new design allowed the pedal crank chain to be adjusted by loosening, rotating and retightening the pedal crank hub - all without disturbing the rear wheel or the drive belt. 1912 was also the first year that Harley-Davidson motorcycles incorporated clutches. The clutch mechanism was mounted in the rear hub. The leather drive belt turned a separate spoked belt rim, which transmitted power through the clutch hub to the rear wheel. Control was by a handlever on the left side of the tank. With this clutch, riders could easy accomplish a smooth start from a dead stop, a feat that had been challenging with the old system of drive belt tensioning. The bicycle pedals were still there for starting the motor, but not for pedaling off and easying motor power into operation. (Hatfield, "Inside Harley-Davdison", 15-18). In the years that followed this model, Harley-Davidson introduced chain drive and a single-speed transmission (1913), internal expanding rear brake, gas lights, side cars and a two-speed transmission (1914), and an electrical lighting system and a three-speed transmission (1915).
