Four Stroke Vs. Two-Stroke Dirt Bikes

Four Stroke Vs. Two-Stroke Dirt Bikes

It is about time to get out the dirt bikes! 

A popular question when searching for a dirt bike near Lebanon, MO is commonly what engine to go with. A two-stroke or four-stroke? It is no secret that gas prices have been rising, so it is important save where you can when it comes to your powersport “toys.” Let’s dive into the two types of engines to help you better understand the differences you can choose between at LSK Lebanon.

How They Work

Each time the piston travels up or down the cylinder is a “stroke.” Both engines depend on this power cycle.

A 2-stroke completes a single power cycle during the one “crankshaft revolution,” which equals two strokes. In the 2-stroke engine, the actions overlap. The end of the combustion stroke is simultaneous with the beginning of the compression stroke…and the intake and exhaust functions are synchronized. 

With a 4-stroke engine, it completes one power cycle during two crankshaft revolutions, equaling four strokes. The 4 strokes correspond with intake, compression, combustion, and exhaust. 

Differences Between the Two

2-stroke engines tend to be the older version of the engine. This is a simpler design, most used in chainsaws or lawnmowers. These engines use a combination of oil and gas. These expel exhaust as well as unused fuel, consuming a significant amount of fuel and more inclined to pollute the air. The upside to this type of engine is it is lighter and easier to repair. You’ll also get more power with every crankshaft turn, instead of every two turns.

4-stroke engines are the more complicated engine yet delivers more power. These engines tend to be a lot heavier than the 2-stroke engines. But the power behind these engines outweighs the heaviness of it. Another benefit is that the 4-stroke engine is much quieter and even smoother to use. These engines also require less maintenance and derives energy from plain gas, not a mix. With a 4-stroke, you will get more “bang for your buck,” when it comes to gas. This engine is more efficient and effective with how it consumes gas, saving you money long term.

How to Decide When Choosing a Dirt Bike

When deciding what engine to choose for a dirt bike it all comes down to personal preference.

You’ll want to go with the 4-stroke engine if you are trying to save money on gas because of the lower fuel consumption. These can also be useful in noise-sensitive areas, as it produces less noise than the 2-stroke. This engine tends to be more efficient, delivering more torque at a lower speed.

A bike with a 2-stroke engine will be lighter and cheaper. For a lighter rider, this may benefit you as the weight ratio is more even and will deliver a jumpier feel on the bike. This bike will also require more shifting than the 4-stroke. Another thing to keep in mind is the 2-stroke will produce more pollution, but the maintenance is cheaper.
