A motorcycle is a motor vehicle with two or three wheels that is powered by an engine and steered by a handlebar from a saddle-style seat. Motorcycles are popular because they offer a more intimate driving experience and can achieve greater fuel economies than automobiles. The most common layout of a modern motorcycle includes a gasoline engine that converts the reciprocating motion of pistons into rotary motion to turn the back wheel and propel the motorcycle forward. The rider controls the engine and brakes by operating levers on the handlebars.
During the 19th century, many different companies began producing self-propelled bicycles and eventually motorcycles. Some are now forgotten, such as Germany’s Hildebrand & Wolfmuller, but others, such as the legendary UK company Royal Enfield and American companies Triumph, Indian and Harley-Davidson all began production around the turn of the 20th century.
The first motorcycles were large, powerful machines designed primarily for racing and sports competition. Later, manufacturers like Honda reinvented the category by making small, reliable motorcycles that appealed to baby boomers who wanted to get away from the crowded roads and high gas prices of the time.
Despite their popularity, the majority of motorcycle accidents are caused by riders who fail to follow basic safety procedures. These include wearing helmets and protective gear, abiding by traffic laws, not riding under the influence of alcohol or drugs (including some prescribed medications) and avoiding riding in adverse weather conditions. Regular inspections and maintenance are key to reducing mechanical failures that lead to accidents. The use of a digital checklist can simplify this process and help prevent mistakes.
