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.
The terms Veteran, Vintage, and Classic have specific time periods that define the terms...IF you are in the United Kingdom. Here in the States, the terms are used arbitrarily, and have taken on different definitions depending on who is doing the defining. Veteran is a term that is rarely, if ever used here. Classic is used arbitrarily for the most part, in some cases the term is used to describe a new vehicle, such as a Hinckley Bonneville. Vintage is a little more defined. It is becoming somewhat accepted that the term vintage applies to any motorcycle 25 years old or older.
