The Basics of Motorcycles

Motorcycles are powered by gas-fueled engines that convert reciprocating piston motion into rotary motion to drive the rear wheel sprockets and propel the bike forward. A clutch and throttle, both controlled by twist-type controls at the rider’s handgrips, are used to control engine speed. The front-wheel brake is operated by a lever near the handlebar; the rear-wheel brake is usually a foot pedal.

In poor countries, small motorcycles are often the main form of personal transportation. In richer countries, motorcycles are generally used as a sport or a hobby. Motorcycle sports include on-road and off-road racing. On-road races are typically held on closed public roads, while off-road races take place on unpaved or difficult-to-drive terrain.

Aside from the obvious dangers of riding a motorcycle, there are many other factors to consider. Buying, training and maintaining a motorcycle can be an expensive undertaking. In addition, some employers and communities view motorcycles as obnoxious noise machines that disturb the peace, leading to bans on motorbikes in certain areas.

When deciding to purchase a motorcycle, educate yourself about the different types of bikes and what they are intended for. But remember that no matter which type of motorcycle you choose, safety is the most important factor of all. Always wear a helmet, and never ride a motorcycle while under the influence of alcohol or drugs (including some prescribed medications). These substances impair judgment, coordination, balance, throttle control and ability to shift gears. They also reduce the reaction time needed to respond to other vehicles and pedestrians.
