Four Stroke or Two Stroke Dirt Bikes?
Deciding on the Bike That's Right For You
If you're looking at buying a dirt bike, there is one key thing that is important for you to know. When it comes to off road bikes, there are two different options as far as engine types: four stroke or two stroke dirt bikes. In order to get the best ride for your needs, it's important to understand the differences between these two types, and the benefits of each. The engine type you choose is going to depend on this understanding, combined with what type of riding you plan on doing.
A four stroke dirt bike engine is designed to have low end torque power. What this means is that its power is slower; when you hit the throttle, the bike isn't going to jump out from under you. Four strokes come in different engine sizes, typically 200cc engines up to 600cc engines. The smaller the engine size, the less power it has. Four strokes are awesome engines for people who do a lot of riding off the track.
Two stroke dirt bikes have more high end torque, are more powerful than four stroke bikes, and their power is quicker to respond when you hit the throttle. Because two stokes have more power ane are snappier to respond, they are perfect for motocross and trick riding. Two strokes come with the same size engines as the four strokes; however, a 200cc two stroke is going to be twice as powerful as a 200cc four stroke.
The difference between a two stroke and a four stroke can be compared to the difference between a diesel pickup truck and a sports car. Both are powerful in their own way, for their individual uses. The sports car is more powerful, and that power can be accessed faster, while the power of the diesel engine is more suited for heavy duty uses. Whether you choose a four stroke or two stroke is going to depend on how you want to use it. Four strokes are best for off roading, while two strokes are best for track riding.
Another difference between these two styles of dirt bike is the gasoline they run on. A four stroke bike runs on regular gasoline, while a two stroke dirt bike runs on a blend of gasoline and two cycle motor oil. Premium grade gasoline should be run in both engines to optimize performance. No matter what style you need, four stroke or two stroke, it's important to choose the right size engine for your experience level. If you are just starting out, a smaller engine is a good choice for you. But if you have been riding for a while, a larger engine might be better for your experience.
Also, don't forget to consider your body type. When we picked out a dirt bike for my wife, who is five foot and 105 pounds, we chose a 200cc dirt bike, because that size engine is just right for a woman of her size. Whereas when my brother, who is pushing 300 pounds, bought a bike, he chose the biggest engine he could get.
Knowing the difference between these two styles of dirt bike is important, and can quickly get you on your way to buying the dirt bike of your dreams.
Most dirt bike manufactures have models around both engine types.
One of Honda's most popular bikes is the Honda CRF series, the larger cc sizes are all 4 stroke bikes.
Most engines under200 are 2 stroke, there are some crazy 2 stroke dirt bikes out there, like the KTM SX250.

Nice post. Good read. Beautifully differentiated the two stroke dirt bikes and four stroke dirt bikes. As mentioned in the post neither of the two can be generalized as which is the best cos the utility of both differs. I think Kawasaki and Yamaha are the best manufacturers of two stroke dirt bikes. Thanks.
