Motorcycles are two or three-wheeled motor vehicles steered by a handlebar from a saddle-style seat. They have a much smaller profile than cars, which makes them slimmer and faster to maneuver. They can also fit into parking spaces that are too small for a car. This makes them popular with urban dwellers and city commuters, as well as people who want to avoid the expense of owning a second vehicle.
The first motorcycles were developed in the early 1900s by converting bicycles with spark ignition engines. These were followed by a number of manufacturers who built motorcycles with purpose-designed engines and lightweight construction. Competition between manufacturers led to reliability trials, which were often held on the Isle of Man.
Today, there are a wide range of styles and sizes of motorcycles to suit almost any riding style or need. The smallest motorcycles are designed to be economical and easy to ride, while larger touring models can carry the rider and passenger in comfort for long distances. Off-road motorcycles can be used for dirt or motocross racing, and have small fuel tanks for lightness and agility.
Before riding a motorcycle, it is important to understand the basic safety principles. Riders should always wear protective gear, including gloves and a helmet. It is essential that riders be sober, as alcohol and drugs (even prescribed medications) impair judgment, balance, coordination, throttle control, and the ability to shift gears. In addition, it is a good idea to postpone rides in bad weather or when roads are slippery or dangerous.
