The definition of a classic motorcycle has been debated many times over by motorcycle enthusiasts. These debates range not only into the age of the motorcycle and its place in the history of motorcycles but also into the style of the motorcycle itself. Taking the different opinions on what defines a classic motorcycle into account, they seem to find their common ground in the age, simplicity, appearance and status of the motorcycle. Generally, a motorcycle that is at least 25 years old and has a simple, traditional look is considered to be a classic motorcycle.
Age is the primary consideration in terms of a motorcycle being called classic. Motorcycles have a long history, and it is considered remiss to call a relatively new motorcycle a classic before seeing how well it stands on its own among the countless varieties of motorcycles that have been produced. 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. Air-cooled, two-cylinder engines, single headlights and double supports on the rear wheel are all considered classic motorcycle hallmarks. Fairings, cast wheels and liquid cooling are examples of things that typically remove motorcycles from consideration as classics.
