The Mechanism Of How A Motorcycle Work?

Motorcycle Riding is not too hard for an individual. If you know the proper steps, you can ride it properly. Sometimes we think that as riders we perform all activities.

The motorcycle does nothing. But is it true in the real sense? Does not the motorcycle do anything? Always remember that people just control the motorcycle, nothing else.

Actually, the main activities were the motorcycle. Are you confused about it? Are you interested to know how a motorcycle works?

Let’s know about it. From this article, all of your doubts will be clear.

Things To Consider For Proper Understanding Of How A Motorcycle Works

Motorcycle work is the combination of some works of different parts. So without the idea of those parts, you can’t think of it. To understand proper mechanics you must know the following things.

These are:

  1. Different parts of the motorcycle
  2. Mechanism of action of the major parts of a motorcycle

Different Parts of The Motorcycle

Firstly we can consider the whole body parts in 4 sections. These are

  1. Front and Back wheel associated parts
  2. Handle parts
  3. Body parts

Front and back wheel associated parts

These parts are located around the front wheel and back wheel. The parts are

  • Front-wheel and back wheel
  • Tire
  • Wheel rims
  • Break clipper
  • Brake disk
  • Front fender
  • Front suspension block
  • Taillights
  • Turn signals
  • Final drive sprocket
  • Rear fender
  • Shock absorber

Handle parts

This part indicates the front parts of the rider. Mainly it has regulatory parts for riders. It consists of:

Body Parts

It contains the remaining parts of the motorcycle.

  • Engine
  • Fuel tank
  • Triple clamp
  • Radiator
  • Swingarm
  • Exhaust muffler
  • Airbox with filter(under the seat)
  • Seat (for both rider and passenger)
  • Footpeg for rider
  • Chain
  • Rear brake level
  • Shift lever

Mechanism Of Action Of The Major Parts Of Motorcycle

This may seem like the individual functions of different parts. But this mainly indicates the motorcycle works. Because these activities are not separate.

They interlink with each other. The Motorcycle Word is nothing but their combination. So their working process is ultimately the motorcycle’s working process.

The mechanism of action is given below:


The engine is the most important part of any vehicle. The major activity occurs inside the engine. It consists of several parts which perform different actions.

The Engines of motorcycles are similar to other vehicles. It has pistons, a head containing a valve train, and a cylinder block. The up-down movement of pistons helps the air-fuel mixup.

It happens inside the cylinder block and a spark helps ignition. In this case, vulve acts as the door of the combustion chamber. Crankshaft transforms energy from pistons to Rotary motion.

The rotational force of the crankshaft is transmitted through the transmission. Then it moves toward the rear wheel. The engine has 3 major characteristics.

First one, the cylinder numbers they have. Then the number of combustion chambers. The third one is the power cycle’s stroke numbers.


Cylinders are the structural units of the engine. The number of cylinders in an engine is not equal. The number may vary from vehicle to vehicle.

In the case of motorcycles, it is 1 to 6. The main function of the cylinder is to carry gasoline. Then burn it and produce energy.

The cylinder function resembles the engine function. In most cases, 2 cylinders are used. It forms V-shaped.

So people call this cylinder V-twin. The cylinder’s position may be angular or parallel or opposite. The angular arrangement reduces the vibration.

So the position of the pistons also varies. At present, 4 cylinders are the most popular design. It provides higher efficiency than 2 cylinders.

The number of cylinders changes but the arrangement is V-shaped.

Combustion chamber

Combustion is also a part of the engine. It is considered as the burning unit of the engine. Combustion chamber size is an important fact.

The size may vary. The power output of the engine depends on it. The chamber size may be 1500 cc to 50 CCs.

The size of the chamber is proportional to the size of the motorcycle. A 50 cc size chamber motorcycle runs 100 miles per gallon. But the speed should be 30 to 40 miles per hour.

So for long distances, the small-sized chamber is not suitable.


The Clutch is the connector of the crankshaft and transmission. It contains a series of spring-loaded plates. To connect the transmission and crankshaft these plates are compressed together.

To start the gear the rider connects the clutch. On the other hand, the rider shifts the gear to disconnect.

Motorcycle transmission

The Energy is produced in the chamber. Now it needs to work to move the motorcycle. For this reason, it must transfer to the rear wheel.

The transmission is the media that transfer energy from the chamber. It transmits the energy to the Gear set.

Gear set

The gear set is the next part of a transmission. It takes energy from the transmission to the next part. The gear set contains a set of gears.

The number of gear may vary. Typically the gear number is 4 to 6. The smaller size motorcycle may contain 2 gears.

It can control speed levels from highest to lowest (stop). Gears shift the lever through which the shifting fork moves inside the transmission.

Drive system

The driver system mainly transports energy to the back wheel. This energy moves the motorcycle. There are 3 types of driving systems.

These are chain, belt, and shaft. The chain system is mostly used. For this purpose, metal chains are used.

It connects the sprocket of the output shaft and rear wheel. Throughout the connection the energy moves to the rear wheel.

With this energy, the motorcycle moves. The system needs to lubricate and adjust. The chain scratch and sprocket wear must replace after a period.

The belt and shaft-final drives function similarly to the chain system. In the beginning, the belt was made of leather. Nowadays people use clogged rubber belts.

Its function is similar to a chain system. But there is no necessity for lubrication.

The shaft-final drives are more popular in some cases.

In this case, a shaft drive is used. This system is more convenient and cost-effective. But its weight is heavier and causes shaft-jacking of the rear wheel.

There is another type of transmission system called a friction drive. It is one type of continuously variable transmission. It is not frequently used.

Frequently Ask Question (FAQ)

What are the essential zones where the oil streams?

By and large, the primary motor territories are the cylinder get-together, heading, and valve train, combined with the need to ensure the gearbox and grease up and cool the grasp.

What’s the capacity of the oil channel?

The oil channel attempts to trap foreign particles and garbage brought into the oil by everyday riding. These particles can prompt motor harm, while an obstructed drain may prompt oil starvation and eventually motor disappointment.

Can motor oil improve execution, or is it just for motor insurance?

Honestly, by diminishing interior grating and drag, the oil can improve motor effectiveness and subsequently upgrade motor execution. Much of the time, this is accomplished using low thickness, rubbing streamlined oils.

For what reason do some OEMs suggest low thickness oil?

It mirrors the need to create more eco-friendly motors, combined with improved assembling measures.

What does a Moto GP motor use as oil?

The oils are altogether different from street oils and customized explicitly to the Moto GP motor. The procedures utilized for growing superior Moto GP oils are being used for our Power 1 oils.

Would I be able to utilize similar oil at excessive outside temperatures?

Indeed, with the utilization of superior base oils, in multi-grade motor oils, we can guarantee that the oil streams when cold and won’t vanish or consume extreme heat when exposed to the high-temperature activity.

Would I be able to utilize a track day oil for street driving?

It’s not fitting as track day oils are planned explicitly for improving execution throughout brief timeframes and may not be reasonable for extended channel use.


As a rider, you must know some basic things about the motorcycle. It will be very effective for your riding and safety. The knowledge of how a motorcycle works are very important.

It will provide you with a better understanding of motorcycle functions. So you can easily understand the importance of its different parts. It will also provide you with knowledge about the abnormality.

You can easily detect the abnormal part through this idea. This will help you to overcome unwanted problems. Thus you will be able to enjoy your journey by motorcycle.
