A motorcycle, commonly known as a motorcycle, cycle, or two-wheeled vehicle, is usually a relatively small four-wheeled vehicle with either a single or two-wheel drive. Motorcycle style varies widely in order to fit a wide range of different functions: street touring, commuting, long distance travel, sports such as racing, and off road riding in extreme conditions. Motorcycle parts vary widely to fit different purposes and styles.
The frame and the suspension system are the most important components in most motorcycles and bicycles. In the United States, bicycles and many other two wheeled vehicles are regulated by the Department of Transportation (DOT) for highway and parking safety. Bicycles and other two wheeled vehicles must have smooth tires with deep treads for maximum traction and safety. Some two wheeled cycles have handlebars that are mounted above the saddle. These bikes can be called cruisers.
Both motorcycles and automobiles have their own names for the controls. Motorcycle controls are generally placed behind the seat, between the handlebars, or between the muffler and the engine. A larger engine on a motorcycle has a greater turning radius; this makes it easier to turn, especially in curves. It also usually requires more muscle to corner because the turning radius is less.
An important distinction between bicycles and motorcycles is the gearbox. Motorcycles have gears in front and back, while bicycles have only one gearbox in front. Both motorcycles and bicycles have single or double gears, with the exception of the front gears, which are normally gears in reverse.
Motorcycle transmissions include a clutch, which allows the rider to slow down or go faster. Clutchless transmissions are easier to start and stop, but do not have a foot pedal. Clutch gearboxes are often chosen for inexperienced riders who want greater control. Foot pedals give the rider an added sense of control and make riding a smoother process.
The size and style of your bike depend largely on what you are looking for. One of the main differences between a motorcycle and a bicycle is that bicycles are smaller and lighter than motorcycles. Motorbikes have four wheels, compared to two wheels on a bicycle. Motorcycle tires are typically wider, with a tread that is deep enough to allow them to grip the road. The motor on a motorcycle has fewer moving parts, so it is far less likely to break. Both bicycles and motorcycles are available in many different styles.
