A motorcycle (also called a motorbike, bike, moto or cycle) is a two or three wheeled motor vehicle. Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sportincluding racing, and off-road riding. Motorcycling is riding a motorcycle and related social activity such as joining amotorcycle club and attending motorcycle rallies.
In 1894, Hildebrand & Wolfmüller became the first series production motorcycle, and the first to be called a motorcycle. In 2012, the three top motorcycle producers globally by volume were Honda, Bajaj Auto, and Hero MotoCorp.
Motorcycles are mainly a luxury good in the developed world, where they are used mostly for recreation, as a lifestyle accessory or a symbol of personal identity. In developing countries, motorcycles are overwhelmingly utilitarian due to lower prices and greater fuel economy. Of all the motorcycles in the world, 58% are in the Asia Pacific and Southern and Eastern Asia regions, excluding car-centric Japan.
According to the United States Department of Transportation the number of fatalities per vehicle mile traveled was 37 times higher for motorcycles than for cars.
In the 21st century, the motorcycle industry is mainly dominated by the Chinese motorcycle industry and by Japanese motorcycle companies. In addition to the large capacity motorcycles, there is a large market in smaller capacity (less than 300 cc) motorcycles, mostly concentrated in Asian and African countries and produced in China and India. A Japanese example is the 1958 Honda Super Cub, which went on to become the biggest selling vehicle of all time, with its 60 millionth unit produced in April 2008. Today, this area is dominated by mostly Indian companies with Hero MotoCorp emerging as the world’s largest manufacturer of two wheelers. Its Splendor model has sold more than 8.5 million to date. Other major producers are Bajaj and TVS Motors.

Motorcycle rider postures.
The motorcyclist’s riding position depends on rider body-geometry (anthropometry) combined with the geometry of the motorcycle itself. These factors create a set of three basic postures.
* Sport – the rider leans forwards into the wind and the weight of the upper torso is supported by the rider’s core at low speed and air pressure at high speed (e.g., above 50 mph (80 km/h)). The footpegs are below the rider or to the rear. The reduced frontal area cuts wind resistance and allows higher speeds. At low-speed this position throws the weight of the rider onto the arms, which can tire the rider’s wrists.
* Standard – the rider sits upright or leans forward slightly. The feet are below the rider. These are motorcycles that are not specialised to one task, so they do not excel in any particular area. The standard posture is used with touring and commuting as well as dirt and dual-sport bikes, and may offer advantages for beginners.
* Cruiser – the rider sits at a lower seat height with the upper torso upright or leaning slightly rearward. Legs are extended forwards, sometimes out of reach of the regular controls on cruiser pegs. The low seat height can be a consideration for new or short riders. Handlebars tend to be high and wide. The emphasis is on comfort, while compromising cornering ability because of low ground clearance and the greater likelihood of scraping foot pegs, floor boards, or other parts if turns are taken at the speeds other motorcycles can more readily accomplish.

Factors of a motorcycle’s ergonomic geometry that determine the seating posture include the height, angle and location of footpegs, seat and handlebars. Factors in a rider’s physical geometry that contribute to seating posture include torso, arm, thigh and leg length, and overall rider height.
