Chopper classic

A chopper is a type of moto cycle that was either modified from an original motorcycle design ("chopped") or built from scratch to have an authentic appearance. The main features of a chopper that make it stand out are its longer motor cycle frame.design accompanied by a stretch front end (or rake). To achieve a longer front end, while the frame is being designed, the will tilt the neck of the frame at less of an incline and install a longerfork. Another unique aspect of a chopper design is that there is usually no rear suspension meaning the frame of the motorcycle will extend from the neck (or front of the frame) all the way to the rear wheel.

This can make handling the motorcycle more challenging and the ride a bit more "bumpy". These attributes may seem radical to some but is necessary for the look that is desired. One look that is becoming more popular with chopper designs is a low frame to ground clearance or a low rider look. Well known examples of chopper designs are the customized harlay davidson seen in the 1969.

Beginning

In 1901, willyam S.harley, age 21, drew up plans for a small engine with a displacement of 7.07 cubic inches (116 cc) and four-inch (102 mm) flywheels. The engine was designed for use in a regular pedal-bicycle frame. Over the next two years, Harley and his childhood friend Arthur davidson, labored on their motor-bicycle using the northside Milwakee machine shop at the home of their friend, Henry Melk. It was finished in 1903 with the help of Arthur's brother, Walter Davidson. Upon completion, the boys found their power-cycle unable to conquer Milwaukee's modest hills without pedal assistance. Will Harley and the Davidsons quickly wrote off their first motor-bicycle as a valuable learning experiment.

Harley Davidson

Founded in Milwaukee, Wisconsin, during the first decade of the 20th century, it was one of two major American motorcycle manufacturers to survive the Great Depression.Harley-Davidson also survived a period of poor quality control and competition from Japanese manufacturers.

The company sells heavyweight (over 750 cc) motorcycles designed for cruising on the highway. Harley-Davidson motorcycles (popularly known as "Harley davidson") have a distinctive design and exhaust note. They are especially noted for the tradition of heavy customization that gave rise to the chopper style of motorcycle.current Harley-Davidson motorcycles reflect the styles of classic Harley designs. Harley-Davidson's attempts to establish itself in the light motorcycle market have met with limited success and have largely been abandoned since the 1978 sale of its Italian AERMACHI subsidiary.
