Difference Between Two Stroke & Four Stroke Motorcycle: Which One Is Best?

We usually know two types of bike engines. Those two names are two-stroke engines and four-stroke engines. But many of us may not know what these two types of engines are. The two-stroke engines were originally used on many earlier model bikes. Of course, some bikes still use two-stroke engines. Today our topic is to know In this article, I will try to make things clear about the difference between these 2 stroke engines and 4 stroke engines. It seems like you are interested about how these two types of engines work. So let’s get started.

Two Stroke Engine Motorcycle

Now I am going to discuss here the two-stock engine. How does it work? There has one revolution of the crankshaft during one power stroke in the two-stock engine. In 2 stroke engines, the piston moves a total of 2 times. The 2 stroke engine is much lighter and costs much less to build and maintain. Another major problem with a two-stroke engine is that it is very expensive. Calculations show that it consumes about 1 gallon of oil per 1000 kilometers. And also it is not suitable for the environment.

Four Stroke Engine Motorcycle

After analyzing two stock engine, now I am going to discuss the four stock-engine. In fact, It has two revolutions of the crankshaft during one power stroke. The piston engine of four-stock is some less than a two-stock engine. It has a lesser ratio in terms of power to weight and it generated less smoke and shows more efficiency. The engines of four-stock are expensive due to lubrication and valves and are tough to manufacture.

Difference Between Two Stroke And Four Stroke Engine

At this time, I am going to present here all the different advantages and disadvantages of the two engines. The engine of two-stock is cheaper and simple for manufacturing, but the engine of four stocks is expensive to manufacture and it is basically heavier. In addition to the information, I have already arranged a list of two-stock engine and four stock-engine at a glance below. To get it, please follow the table below carefully.

Two stock Four stock
It has one revolution of the crankshaft during one power stroke It has two revolutions of the crankshaft during one power stroke
It generates high torque It generates less torque
Its uses port for fuel’s outlet and inlet It uses valves for the outlet and inlet of a fuel
Its engines result in lesser thermal efficiency Its engines result in higher thermal efficiency
It has a larger ratio in terms of power to weight It has a lesser ratio in terms of power to weight
It generates more smoke and shows less efficiency It generates less smoke and shows more efficiency
Requires more lubricating oil as some oil burns with the fuel Requires less lubricating oil
Due to poor lubrication, more wear and tear occurs Less wear and tear occurs
Engines are cheaper and are simple for manufacturing Engines are expensive due to lubrication and valves and are tough to manufacture
Engines are basically lighter and are noisy Engines are basically heavier because its flywheel is heavy and are less noisy

Which Engine Is Better Overall?

Now it is time to decide which engine is better. It must be said that the 2 stroke engine is very good in terms of performance. And its power is much higher. But, if we think from the overall point of view, then the 4 stroke engine is also perfect. If you need power and you have a lot of money in your pocket then 2 stroke engine is definitely good for you. And usually, a 4 stroke engine seems to be good for any rider. And just remember 4 stock engine is good for the environment.
