However, two-stroke parts are notoriously cheaper than four-stroke. Two-stroke engine bikes are lighter and faster bikes that have an intense kick to the motor. This makes it easier to throw around your bike with the faster punch per cc. At the same time, these bikes are usually more difficult to ride and control.

A stroke is a motion of a piston, meaning a two-stroke dirt bike has 2 different motions of the piston, while a four-stroke has 4. 2 Strokes are generally more unstable and accelerate faster, while a 4 stroke is more consistent and has a higher top speed. But this debate goes so much deeper than the simple question, “which is better?”.

Two stroke dirt bikes: Two-stroke dirt bike engines take part fully in two processes which are crucial, compression and combustion. Remember the spark plug that we mentioned above, well, the spark plug ignites when the engine fires, and it is much simpler with two-stroke dirt bikes.

Two-stroke dirt bikes are ordinarily noisy and create more debilitating exhaust, but ...

The two-stroke engine produces the equal amount of power of a four-stroke engine with the half of four-stroke engine CC. For instance, a two-stroke dirt bike with 125cc power will generate the same amount of energy of a 250cc four-stroke engine. However, four-stroke engines with low cc are rarely found in the market now.

Four strokes are known for being expensive to to rebuild. Two strokes, on the other hand, are known for being relatively easy to work on and inexpensive (comparatively) to rebuild. However, when you get into the standard maintenance like cleaning the air filer and changing the oil, the two bikes are the same. Is a 2 Stroke or 4 Stroke Better?

So… what may be needed now, to ensure the future of “two-stroke dirt bikes”, is a low-tech (i.e. cheap), clean, economical two-stroke motorcycle. The ‘death’ of two-stroke dirt bikes has come after the loss of two-stroke motorcycles in general; and I believe that the future of two-stroke dirt bikes may have to come after a revival of the wider market.

Two-stroke engines are typically found in smaller vehicles like small cars, chainsaws, boat motors, and dirt bikes. Four-stroke engines are found in anything from go-karts, lawnmowers, and dirt bikes, right up to the standard combustion engine in the vehicle. It’s up to you to make your decision which engine you choose to have and for why.

A two-stroke has the same four-stage engine cycle, but it does it all in just one rotation of the piston. It uses intake and exhaust ports along the cylinder wall to manage intake and exhaust gases, creating an organic exchange of pressures and vacuums without the use of valves, fuel injection, or even an accelerator pump.

How does a 4 stroke dirt bike engine work?

Now the piston begins to rise again. The exhaust valve opens up and releases the emissions from within the cylinder,...
