2 Stroke vs 4 Stroke Dirt bike: Which One Is Good For A Beginner?
Before buying a dirt bike for you or your children, you need to consider a lot of things. Dirt bikes come in many sizes and specifications. And among those, the most important thing is choosing the engine type.
Dirt bikes come in both 2-stroke and 4-stroke engines. And there’s been a debate for decades between which one is the best! Although experts know how they are and which one they should go for, choosing the right one is really challenging for beginners.
To clear out the confusion and help you choose the right one, today, we’re here with a new article on 2 stroke vs. 4 stroke dirt bikes. Here, we’ll cover everything related to 2-stroke and 4-stroke engines alongside their pros and cons.
2 Stroke vs. 4 Stroke Dirt Bike: Pros and Cons
We know how challenging it is to choose a dirt bike between a 2 stroke and 4 stroke engine. But don’t worry. We’ve a proper guideline so that we can know about these engines and finally select one depending on your choice.
What is a 2 Stroke Dirt Bike?
There are piston cylinders in the engine chamber in a motorcycle. This goes for dirt bikes as well. The pistons complete engine cycles to produce combustions and run the bike. When the pistons complete the engine circulation in only 2 rotations/movements, it’s called a 2 stroke engine.
Besides the 2-stroke engine, another type of engine is called the 4-stroke engine. Between the two, the working principle of a 2-stroke cylinder is simple and less complicated.
The working of a 2-stroke engine starts with a power stroke. Firstly, air and fuel mixture enters the engine chambers. After that, they’re compressed by heavy pressure. This pressure pressurizes the piston and forces it down, which eventually helps the mixture to get out from the exhaust chamber/pipe. This is a continuous process, and the piston cylinders move simultaneously, creating a spark and igniting the vehicle.
The 2-stroke engines are equipped with fewer parts compared to other engines. Besides, they also come with an efficient build. That’s why 2-stroke engines emit less waste, and they’re easier to maintain at the same time.
Air-fuel mixtures are a must for 2-stroke engines. Both the intake and outgoing occur at the same time. As a result, they need more maintenance. But the good news is, they’re easier to clean, and their parts are easily available and cheap.
Simply put, 2-strokes engines just need 2 rotations or movements to produce the ignition on the power required for moving/running the dirt bike. So they’re efficient. Dirt bikes equipped with 2-stroke engines are lightweight and cheap but produce high-pitched sound!
Pros:
- Lightweight
- Cost-effective and Cheap
- Maintenance is easy
- Efficient build
- Parts are easily available
Cons:
- Needs more shifting
- Needs frequent maintenance
What is a 4 Stroke Dirt Bike?
A 4-stroke engine is a little complicated compared to a 2-stroke engine. But don’t worry. We’ll explain it as simply as we can. Like the 2-stroke engine, the 4-stroke engine cylinders also make engine cycles. But instead of 2 circles, here, 4 circles occur. This is 2x times more than a 2 stroke engine. Due to this, the engine becomes heavy and complicated to operate.
A 4-stroke engine works in 4 steps. They start with our intake and end at combustion. Between intake and exhaustion, compression and combustion occur. This type of engine fires/sparks after every 2 rotations/movements of a crankshaft.
The spark production and exhaustion process in a 4-stroke engine are almost similar to e 2-stroke one. The spark or ignition is steady as the cylinder moves and rotates. As a result, a better output comes in a 4-stroke engine. One thing to note is that the movement of the cylinder, combustion, intake, and exhaust occurs for the whole time when a motorbike is on running. The process only stops when you stop your bike.
A 4-stroke engine provides better output as well as needing less maintenance. But they have numerous parts, which is a hassle considering the maintenance cost. And most of the time, the maintenance cost of a 4-stroke engine is high!
Finally, if you’re wondering which one between 2 stroke or 4 stroke dirt bikes is for beginners, then let me tell you that, a 4-stroke engine will be the better choice as they have a better output, need less maintenance, and are overall easy to handle!
Pros:
- 4-stroke engines need less shifting
- Easy to ride
- Better power output
- Needs little maintenance
- Highly recommended for beginners
Cons:
- Heavy compared to a 2-stroke engine
- More maintenance cost
