What Are The Basic Parts Of A Motorcycle?

Surely no one is unfamiliar with motorbikes because they accompany you every day. However, not everyone understands the structure of a motorcycle and the principle of its operation. Are you curious about the structure of the car you are driving every day? Let’s start with the article What Are The Basic Parts Of A Motorcycle?

Basic components of a motorcycle

We always see motorcycles with many models and designs. However, the basic structure to make a motorcycle is the same. According to What Are The Basic Parts Of A Motorcycle? there are 7 basic parts in the structure of a motorcycle.


Motorcycle frame


Almost all items have a basic frame, and motorcycles are no exception. The frame is a necessary condition to create the basic shape of a motorcycle. To balance the front and rear wheels, it is necessary to fine-tune the motorcycle frame. More specifically, the chassis is an important skeleton of the motorcycle engine and transmission.

Without a frame, the motorcycle would not have engine support. The electrical devices for starting the car also have no place to mount. More importantly, the chassis is strong enough to withstand the load. Because motorbikes have to carry people, and luggage and are greatly affected by the road surface. This is the next information in What Are The Basic Parts Of A Motorcycle?

Classification of chassis according to 2 criteria

– Shape: There are 4 shapes of motorcycle frame including:
– Rhombus frame
– Cradle-shaped chassis
– Skeleton chassis
– Echo frame
– Materials: There are 5 types of materials used to make motorcycle frames
– Frame made from steel pipe
– Chassis made from sheet steel
– The chassis is a combination of sheet steel and steel pipes
– Frame made of aluminum alloy

Depending on the brand, the manufacturer segment will choose different materials and frame shapes for the vehicle.

Motorcycle engine

This is an important part of the motorcycle structure. It determines the performance quality of a vehicle. Those who love speed and want a great driving experience will love motorcycles with powerful engine blocks. Whether the motorcycle accelerates well, how smooth the glide is, the engine is the decisive part.

The structure of motorcycles in the engine, different models are also equipped with different engines. There are two main types of engines: 2-stroke engines and 4-stroke engines. This is the next information in What Are The Basic Parts Of A Motorcycle?

2 stroke engine

This type of engine is usually equipped in older models. Some current motorcycle models are also equipped with 2-stroke engines. Vehicles equipped with 2-stroke engines often have white smoke and slightly noisy exhaust.

4 stroke engine

This type of engine is common in motorcycles on the market today. Especially for scooters, companies will be equipped with 4-stroke engines. This engine is heavier in weight. Also, because the fuel that burns is a mixture of gasoline and air, there is no white smoke.

Battery for power supply

Start the ignition system to help ignite the fuel that requires a battery. This is an equally important part of the motorcycle structure. The battery is a place to store electricity, providing energy to activate the engine ignition system. There are two types of batteries used on motorcycles: water batteries and dry batteries.

Drive system

For the vehicle to move, a transmission system is needed. The sprocket part is the necessary structure of the motorcycle. They are responsible for transferring power from the engine system to the wheels. Although the sprocket has a simple structure, it is very important. Because it determines the vehicle’s operating system. Whether the motorcycle runs smoothly, smoothly up and down slopes depends on the quality of the transmission.


It is a very small part of the motorcycle bridge, but it determines the safety of the rider. The function of the brake is to slow down and stop the vehicle when necessary. Helps drivers avoid unnecessary accidents. Each type of motorcycle will have a different brake operation.

In motorcycles: Need to use the front brake, and squeeze the right-hand brake. Need to use the rear brake, then step on the lever on the right foot.

In scooters: Use the front brake, then squeeze the left brake. Using the rear brake, squeeze the right-hand brake.

Air filter

Occupying a very small area in the motorcycle structure, it is likened to the engine lung. The function of the air filter is to filter the air entering the combustion chamber. Remove dust and impurities in the air to ensure fuel quality.

Thanks to the air filter, there is always a flow of clean air into the combustion chamber to increase fuel combustion efficiency. This helps the engine to operate much more efficiently. There are two common types of air filters: paper air filters and sucker air filters. Depending on the type of motorcycle, the motorcycle manufacturer uses the appropriate type of air filter. After a period of use, you can clean or replace the air filter.



The basic structure of a motorcycle cannot be complete without wheels and tires. There is enough engine and fuel, but for the motorbike to move, it needs to be in contact with the road surface. And the wheel is the part that holds this task.

Is the only motorcycle structural part that has a tight connection with the ground, reducing friction and helping the vehicle move. In addition, tires also affect the reaction speed of the car. Such as traction, braking, and load capacity … if not effective, the tire needs to be replaced. So, we have learned the basic motorcycle structure in What Are The Basic Parts Of A Motorcycle? In the next section, I will learn a bit about the working principle of the engine.

Working principle of motorcycle engine

The engine is one of the most important parts of a motorcycle. It is also the part that many people are most interested in because it greatly affects the operation of the motorcycle. Understand a little about the operating principle of the car engine to care for and use the motorcycle properly. This is the next information in What Are The Basic Parts Of A Motorcycle?

Working principle of 2-stroke engine

2-stroke engines operate mainly at the beginning and the end of the stroke. The job of the first stroke is to do work and compress the water, this is when the piston begins to come to a fixed point. The igniter will then ignite the air-fuel mixture contained in the combustion chamber on the piston.

The first process works when the temperature increases and the pressure increases pushing the piston down. After the piston is pushed up, create a space below to suck in air. After sucking in air, the piston compresses down and pushes the gas mixture to move from the compression chamber to the cylinder through the air duct. At this time, the air duct opens and sends the exhaust gas out.

The exhaust hole and the air duct will close after the air mixture is pushed out. Just like that, the piston moves up after the pressure stabilizes again, starting a new cycle.

Working principle of 4-stroke engine

With a vehicle using a 4-stroke engine, the operation will be more complicated. There are 4 cycles when the engine is operating: intake, compression, explosion, and exhaust. They work alternately continuously to ensure enough air and fuel for the engine to operate.

It can be seen that a motorbike is quite small, but the structure of a motorbike is not simple. Hopefully sharing in the article What Are The Basic Parts Of A Motorcycle? will help you understand more about the car and have a good way to take care of your motorbike.
