Motorcycles are two or three-wheeled motor vehicles that are steered by a handlebar from a saddle-style seat. They are popular for riding on highways, as well as for commuting to work or school.
The engine of a motorcycle is typically a two- or four-cylinder air-cooled gasoline engine ranging in size from 50 to 1,500 cc (cubic centimeters). A motorbike’s power is usually transmitted through a transmission. The most common transmission system is a sequential manual shifter that works with a foot pedal.
A suspension system keeps the bike stable and smooth when moving forward or backward. Front-wheel suspensions use hydraulic shocks to connect the fork to the wheel and absorb impacts. A rear-wheel suspension uses springs to connect the frame to the axle and cushion the bike’s weight.
There are several types of motorcycles, each of which serves a different purpose. Some are designed specifically for certain kinds of riding, such as a dual-sport bike that can be used on the road or off-road.
Cruisers are the largest class of bikes, accounting for 40 percent of registrations in 2021 (Teoh, 2021). Standards are another popular type of street bike that can be used on public roads or off-road.
Standard and sport bikes can be found on the market in a wide range of styles, from sleek and modern to classic and retro. There are also a number of custom-built motorcycles, such as those produced by Harley-Davidson and Indian Motorcycle.
Many motorcycles feature a high power-to-weight ratio, which means that they can accelerate quickly and brake easily. This is great for experienced riders, but can be dangerous for inexperienced ones. Riders should always choose a bike that matches their experience level to avoid dangerous situations.
