Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles.[1] EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.
The general consensus is that a classic motorcycle must be at least 25 years old. Another consideration of what constitutes a classic motorcycle is the simplicity of the bike itself. To be considered a classic, a motorcycle should maintain simple aesthetics hearkening back to the origins of these vehicles.
A classic is an outstanding example of a particular style; something of lasting worth or with a timeless quality; of the first or highest quality, class, or rank â something that exemplifies its class. The word can be an adjective (a classic car) or a noun (a classic of English literature).
