Two-stroke and four-stroke dirt bikes

Two-stroke and four-stroke dirt bikes are both really powerful machines, but there’s still a lot of debate as to which is better. In this article, we’re going to break down the main differences between the two and hopefully help you decide if a two-stroke (2T) or four-stroke (4T)  dirt bike is right for you.

Some of the main factors we’ll be discussing include power, weight, maintenance cost, reliability, sound, price, speed and of course performance

Also, it’s important to consider your fitness level and the terrain you’ll be riding in, whether you are planning to do motocross track riding and jumping  or whether you plan on doing professional motocross racing.

So if you’re curious about which is better: the two-stroke or the four-stroke dirt bike, keep reading to find out…

What is the difference between 2-stroke and 4-stroke dirt bikes?

So the main thing that separates these two bikes is the way they power.

A 2 -Stroke (also called 2-stroke or 2t) engine is an internal combustion engine of a motorbike that has two piston strokes for every revolution of the crankshaft. An engine with two strokes, one for intake and one for exhaust, and no other strokes.

A 4-Stroke (4t cycle) on the other hand, has four-piston strokes per revolution of the crankshaft. Fuel and air are drawn into the engine, mixed and compressed, ignited by a spark plug, and the resulting exhaust is expelled.

To put it simply, In a two-stroke engine, you get a push two times in a single revolution, while in a four-stroke engine, you get a push four times.

However, two-stroke engines deliver each push with more power, but the trade-off is that they wear out quicker.

During a single revolution, four-stroke engines push four times, but the power of each push is lower. With this system, you can enjoy higher top speeds with less effort while steadily increasing power.

2-Stroke: Pros and Cons

This is the original dirt bike. A 2 stroke dirt bike is an engine that’s typically found in motocross and used for light off-road use.

Because of the design of the 2 -stroke engine, it is more lightweight and less complicated than a 4 -stroke engine. This enables it to be initially cheaper and easier to repair than a four-stroke engine.

It’s able to produce a great deal of power at really low RPMs. But the power band is very narrow, so the rider has to change gears a lot more to keep the bike accelerating with full power. Plus, mixing oil and fuel is a really difficult thing to master.

A lot of people will argue that it’s much more difficult to learn on a two-stroke, especially if you’re a beginner.

The two-stroke engine makes a higher-pitched noise than other types of engines because of its design, which can be more troublesome for people who are not used to biking.

The exhaust gases cause more pollution than the other types of engine.

The downside to this type of bike is that it is not as reliable as other bikes. It can require more maintenance than other bikes because it has fewer moving parts.

A 2 stroke also produces more vibration than a 4-stroke dirtbike which can become tiring, but many say this type of engine provides more power for its weight.

4-Stroke: Pros and Cons

This is the current trend for motorcycle manufacturers. Inspirations from old-school bikes, modern technology, and engineering have created a new world for power in the dirt bike world. The 4-stroke motor has a new design that revs the piston more steadily, with more power and less noise. This is the current state of the art in dirt bikes.

A 4-stroke dirt bike is an engine that’s typically found in enduro racing and used for both off-road and on-road use. This type of bike is more efficient and requires less maintenance than the 2 strokes. This type of bike also produces less vibration than its 2 stroke counterpart, which can make riding this bike more enjoyable for extended periods of time

A four-stroke engine has a wider power band which means it is more powerful at high RPMs and easier to keep up with shifting gears. It refers to reaching faster top speed with minimal effort.

It has a separate oil sump that is enough to lubricate the engine, so you don’t have to mix fuel and oil. It also leads to better fuel efficiency. This is because the engine doesn’t have to work as hard as a two-stroke engine. The downside of a 4-stroke engine is that it’s not as light or as cheap as its 2-stroke counterparts.


Is A 2-Stroke A Good Beginner Bike?

Yes, it can be. Whether you are an experienced rider or a beginner, it all boils down to riding skills and your ability to ride a 2 stroke dirt bike. It will take time to master its acceleration and you might need to learn how to shift gears so that you keep the bike running smoothly within its powerband. If you are not comfortable with these things then I highly recommend getting a 4-stroke dirt bike instead.

Why is 2-Stroke Faster Than 4-Stroke?

2-strokes have a narrow power band, which only lasts for a short period of time. So, this means that you will get up to a high speed faster since the bike can only produce power for a short period of time. In contrast, the 4-stroke has a wider range of power that makes it consistent and easier to control for beginners. This also means that once you get used to it, you will go up in speed more easily than if you were riding a bike with 2 strokes, but four-stroke motorcycles will have more top-end speed.

Why is 2-Stroke Better For Enduro?

The reason why a 4-stroke is better for Enduro is that it makes more torque and power than a 2-stroke. But, if you know how to control a 2 stroke in its power band then it can be just as good as a 4 stroke.

Which Is Better For The Environment?

A 4-stroke bike is more eco-friendly because of its ability to produce torque and power more efficiently without the use of oil. This means that pollutants are reduced when ridden by a four-stroke engine, which is better for the environment.

2-Stroke Vs 4-Stroke Dirt Bike Which One Is Better For Beginners?

Note that this question is related to potential quality, not performance. So if you are looking for a bike that will be easy to handle, then you should get a 4-stroke dirt bike. Besides having more power and torque, a 4-stroke is better for beginners since it has a wider range of power.

Which Is Better For Racing?

A 4-stroke dirt bike is usually preferred by racers because it makes more torque and power. So, if you want to do drag racing or participate in racing events then most likely a four-stroke dirt bike would be your best option, most motocross events now only permit 4 stroke motorcycles to compete

2-Stroke Vs. 4-Stroke Dirt Bike which one is better for off-road?

Both can be good for off-road riding. The key difference here is the type of terrain you will ride on. If you are looking for a bike that can handle the rough, challenging terrain then I would recommend getting a 2 stroke dirt bike.

2-Stroke Vs. 4-Stroke Dirt Bike For Trail Riding?

If you are looking for a bike that can handle the rough terrain, then I would recommend getting a 4-stroke dirt bike. A 2-stroke can be unstable when riding on uneven surfaces, and the heavy vibrations will make it hard for you to control the bike.

What’s Better For Motocross 2-Stroke Or 4-Stroke?

Motocross is a very technical and fast-paced event, so whichever bike you choose should have the best performance for motocross events.

If you are interested in motocross, I would recommend a 4-stroke dirt bike because it has more power and torque than a 2-stroke. However, if you are more interested in off-road racing, a 4-stroke is the better option.

Choosing Between A 125 2-Stroke Or 250 4-Stroke?

It all comes down to the type of bike you would want to ride. If you prefer off-road riding, I recommend a 125 2-stroke. But if you are more interested in on-road riding, I would go with a 250 4-stroke.

Conclusion: Is A 2-Stroke Or 4-Stroke Dirt Bike Better?

Both engine types have their ups and downs, but out of all the different types of bikes on the market today, these are the bikes that people enjoy riding and continue to purchase in large numbers. The only real difference between a two-stroke dirt bike and a four-stroke dirt bike is that the latter is more reliable, more fuel-efficient, easier to maintain, and more cost-effective.

Overall, a four-stroke dirt bike is better to learn because you can have more confidence and fewer problems when it comes to maintenance, and you can get more power out of it when it comes to speed.

In the end, it’s all about what makes you happy! And I wish you luck in your quest for that perfect bike!

2-STROKE vs. 4-STROKE Dirt Bikes – Factors to Consider

There are many different factors to consider when comparing two different dirt bike engines with two different modes of propulsion. The engine performance, cost, maintenance, speed, and durability are all major factors to consider when deciding which dirt bike is right for you. Now let’s break these down!


“The lighter, the better.” One of the main factors that make a dirt bike faster is its weight. The lighter a bike is, the faster it will go, and the faster it goes, the more fun you will have. That’s why 2-stroke engines (the “revvy” bikes) are so good. They are lightweight, and they are quick. It is because they don’t have any valves or fuel injection systems like their 4-stroke cousins do. But there is not a huge difference, only 4-8 kgs. So it is not a deciding factor for most consumers.

Ease of maintenance

The two-stroke dirt bike is a good choice if you want to have a bike that you can easily maintain and keep running. It doesn’t have as many parts that need 2-stroke oil to be mixed with the fuel. A 4-stroke dirt bike is a better option for those who don’t want to work on their bike as often because there’s not as much maintenance required. The 4-stroke dirt bike has more parts that need to be lubricated, so as long as maintenance is kept up your 4-stroke motorcycle will be relatively reliable.

As the new four-stroke engines have some advanced technology, so major servicing should be done by a qualified technician, so the cost of that maintenance could mean more than maintenance for a 2 stroke dirt motorbike. To sum it up, if you are looking for a new motorcycle to ride and have a limited budget for maintenance, then a two-stroke bike will suit your needs better. Or if you want a motorcycle with less maintenance, then go with the 4-stroke engine.


As a 2-stroke engine is a less complicated design, it is also less reliable than a 4-stroke engine. It is very likely that a 2-stroke engine will wear out more quickly than its 4-stroke counterpart. It also makes more noise and pollution than the other types of engines, which might not be the best thing for the environment, that’s one of the major factors, most of the manufacturers are building 4-stroke motorcycles


A 2-stroke engine’s power band is narrow, meaning it only has the ability to produce power for a short amount of time before slowing down. A 4-stroke engine, on the other hand, has a wide range of power that makes it consistent and able to be handled more easily. So, as a result, you get to  a certain speed in less time with a 2-stroke bike and get to a higher top speed with less effort with a 4-stroke. But if you can master the art of shifting gears to keep your two-stroke bike in its powerband, then you can use the power to go faster. So, if you are a beginner and don’t have the skill and technique to handle a 2-stroke, then the 4-strokes will be your best option.

Easy to ride

A 4-stroke dirt bike is easier to ride compared to a 2-stroke. With 4 strokes it doesn’t make as much vibration which makes it more comfortable to ride. It also makes less noise to annoy other riders or pedestrians, and also it is easier when slowing and turning. That’s why the 4-strokes were made for both off-road and on-road purposes. But if you are looking for a 2-stroke motorcycle, which I highly recommend, you first learn on a four-stroke so you can build up both skill and techniques, before changing over to a 2-stroke.

A 2-stroke requires more skill to ride compared to a 4-stroke. It is much more tiring and more physically demanding to ride a 2-stroke, but once you learn how to master it then it can be one of the most fun and enjoyable bikes to ride. The feeling of having this bike vibrate at high revs, hearing the growling sound of the motor, and learning how to control its torque is what makes riding a 2 stroke dirt bike such an adrenaline rush.


2-strokes usually have a cheaper price tag as compared to 4-strokes. They are cheaper to buy, cheaper to maintain, and fix. So if you have a tight budget, then you might want to consider getting a 2-stroke dirt bike. But if your wallet can stretch out a little more then I would recommend getting a 4-stroke dirt bike. They are just as cheap to maintain but they do not vibrate much and they can be ridden on both off-road and on-roads, but they are usually more expensive to buy.


A 4-stroke makes a mechanical whirring sound compared to the deep, low vibrations of a 2-stroke dirt bike. So if you are looking for an easier sound to listen to while riding, then you should go with the 4 strokes. It is less noisy and more consistent in power compared to that of a 2-stroke.
