The Harley Davidson Hummer was a small, lightweight motorcycle manufactured by Harley-Davidson. Harley Davidson debuted their new, light-weight motorcycle model in 1948, and it was refered to as the Harley “Model 125”. It utilized a 125 c.c. two-stroke engine, a three-speed transmission, and a unusual front suspension that used a girder style fork, which was suspended by large rubber bands. In 1951, the rubber band style front fork was upgraded to a spring-dampened “Tele-Glide” front fork. In 1953 the engine size was increased from 125 cc to 165 cc, and the model name was changed from a “Model 125”, to the “Model 165”. The Model 165 sported chrome rims, a battery, and a generator powered ignition and lighting system. By the mid 1950’s, sales of the Model 165 were begining to slow down. Harley Davidson was loosing sales to less expensive motorcycle brands, such as Cushman. Despite low sales numbers, Harley maintained the Model 165 for 1955, yet in an effort to lower costs and increase sales, they introduced a brand new, stripped down model called the Harley Davidson “Hummer”. From 1955 through 1959 Haley Davidson offered consumers both the Model 165 as well as the new, more affordable Hummer. The new Hummer model offered a lower price, black painted wheels instead of chrome, and a simple magento style ignition and lighting as opposed to the Model 165’s chrome wheels and battery style ignition and lighting. From 1955 through 1959 Haley Davidson offered consumers 2 different lightweight options, including both the Model 165 and the more affordable Hummer. Both models were popular with beginers, young riders, and with veterens returning home after serving World War 2. The Model 165 and the Hummer models were discontinued at the end of the 1959 model year. A new model, the Harley Davidson “Super 10” (10 Cubic Inch’s = 165 cc) was introduced in 1960, only to be discontinued in 1961. For 1962, Harley increased the engine size slightly to 175 cc, and offered 3 new variations including the Pacer, Scat, and Ranger. The 1962 Harley Pacer was a lightweight street bike, that offered a headlight, tail light, and full fenders. The 1962 Harley Scat was a trail bike that offered lighting, yet also offered a high mounted exhaust and high mounted fenders for trail riding. The 1962 Ranger (1 year only) was Harley Davidson’s rugged, off road bike with aggressive Grass Hopper tires, no lighting, and a high mounted exhaust. The 1962 Ranger was discontinued after just 1 year. From 1963 through 1965, the Harley Davidson Pacer and Scat models gained a rear suspension for the first time. The hard tail frames were upgraded to a swingarm suspension, dampened via springs. 1966 was the last year of the American made, Harley Davidson lightweights and this model was named the Harley Davidson “Bobcat”. The 1966 Bobcat was a unique, 1 year only model, that sported a ABS body, that wrapped around the fuel tank and frame. Although many parts will interchange throughout the series, the 1966 Bobcat was a futuristic ending, to the American made Harley Davidson lightweights that were made in Milwaukee, from 1948 to 1966.
