A motorcycle is a two-wheeled vehicle powered by an internal combustion engine that runs on gasoline. The frame of a motorcycle is usually made from steel, and it includes handlebars, a seat, and two tires (front and rear). A headlight, a taillight, turn signals, and a horn are common features of most modern motorcycles. Some models also feature a windshield for protection from the elements.

In addition to being a means of transportation, motorcycles are used for racing and sport. Many professional races, such as street, drag, and motocross, take place on motorcycles.

Non-racing uses for motorcycles include pleasure riding, commuting, and hauling. They are typically cheaper to purchase and maintain than cars, taking up less space in parking lots, and are much more efficient on fuel. For the rider, a motorcycle is a dynamic and more immersive experience than driving an ordinary automobile. The rider’s body is part of the machine, and movement of the body affects steering, braking, and acceleration.

In developing countries, many people use motorcycles for daily transportation. In places like India and Indonesia, over 80 percent of households own a motorbike. Aid organizations rely on networks of skilled motorcyclists to deliver life-saving medical care to remote areas where there are few other options for delivery. In the United States, motorcyclists enjoy a wide variety of styles and capabilities, from entry-level scooters to full-size sports bikes that can be ridden with a standard driver’s license.
