Motorcycles are a popular mode of transportation used for various activities, such as commuting, traveling, and racing. Compared to cars, motorcycles are more flexible and space-saving, making it more convenient to drive in the city.

In 1885, German inventor Gottlieb Daimler installed an engine into a frame machine, giving birth to the world's first motorcycle. It uses an internal combustion engine and a rear wheel that can be controlled with pedals. Over the ensuing decades, motorcycles underwent many improvements and developments.

A motorcycle is made up of five main parts: engine, transmission system, driving system, steering and braking systems, and electrical instrumentation. It is essential to know the overall structure of the motorcycle and the names of each part.

Motorcycle sports, which involve the use of motorcycles, are a type of competitive sport. It is divided into two types: two-wheel and three-wheel. The form of competition can be divided into cross-country races, multi-day races, road races, track races, and travel races.

To ensure safe driving, there are precautions that one must take when operating a motorcycle. These include:

1. Inspection: Carefully check the operation of each part of the motorcycle, especially the tire pressure. The air pressure of the tire should not be too high to avoid sudden tire inflation.

2. Do not run in parallel with large vehicles: Large vehicles have a certain visual blind area, and it is easy to cause traffic accidents when they suddenly lane change or a brake. Driving motorcycles should avoid large vehicles as much as possible.

3. Maintain a safe distance: During driving, keep a sufficiently safe distance from the vehicle in front so that you have sufficient reaction time and distance in case of an accident.

4. Wear a safety helmet: When driving a motorcycle, wear a safety helmet that meets national standards to protect your head from impact and injury.

5. Wear suitable clothing: Wear suitable protective clothing and shoes to protect the body from friction and falls. Avoid wearing clothes that are too loose or easy to hang on the car to avoid danger.

6. Drive cautiously: Pay attention to the road conditions while driving, avoid driving on dangerous roads such as potholes, muddy roads, narrow curves, etc., and obey traffic rules, especially not running red lights or going against the road.

7. Avoid fatigue driving: Driving a motorcycle for a long time can easily cause fatigue and affect driving safety. Take a break in time, avoid continuous driving for too long, and avoid driving after drinking.

8. Maintenance: Maintain the motorcycle in time, check the condition of the motorcycle, and replace worn parts to ensure the safety and stability of the motorcycle.

Operating a motorcycle requires a certain level of skill and experience. It is crucial to always prioritize safety and adhere to traffic rules to ensure safe driving.
