What Is a Motorcycle?

Whether you love the camaraderie of a group ride on a weekend or the vistas of an off-pavement excursion, motorcycling engages all your senses and creates a feeling of freedom that can’t be matched by a car. Motorcycling also is more economical than driving, and it’s easier to keep your bike safe and in good condition.

It’s easy to get confused by the various types of motorcycle, especially if you’re just starting out. If you’re a first-time rider or looking to upgrade your current ride, it helps to know what makes one type different from another.

Some people refer to their bikes by slang terms like ‘hog’ or ‘chopper’, depending on their personal preference and the style of motorcycle they have. Others stick to the formal term, “motorcycle,” when it comes to formal documentation or insurance.

The reason for the difference in terminology is that not all states used the same definition when reporting highway statistics to the Federal Highway Administration (FARS). This resulted in erroneous data about the number of motorcycles on the road, and it was clear that a standard definition needed to be adopted.

The official definition of a motorcycle is two- or three-wheeled motor vehicles steered by handlebars from a saddle-style seat. The engine is in the rear of the vehicle and can be either side- or inline-four-cylinder. It is primarily powered by an internal combustion engine, although some models are electric. Weight is a consideration when handling a motorcycle, and manufacturers strive to keep center of gravity low for stability and maneuverability.
