2 stroke vs 4 stroke dirt bike: Pros and Cons
The 4 stroke dirt bikes, as their name suggests, have 4 work strokes or phases. These are suction, compression, combustion phase and ejection phase.
The difference between 2 stroke and 4 stroke dirt bikes with internal combustion has been interested in drivers for years, and as there have been various interpretations and contradictions, the majority is still in doubt. The reason for this is that both concepts have their own admirers and are therefore subjective in this regard.
The main things of 2 stroke vs 4 stroke dirt bike would be:
• 2 stroke dirt bikes have a simpler, cheaper and easy to maintain performance.
• The “gas” response in the 2 stroke bikes is far too fast.
• Greater fuel efficiency.
• It is incredibly large (compared to 4 strokes) the number of rpm in the unit of time.

4 stroke engine dirt bike:
During suction, the piston comes from the top to the bottom of the cylinder, reducing the pressure inside the combustion chambers. Then the fuel and air mixture is injected into the cylinder via the injector, and then the tapping effect is followed.
As the suction and discharge valves are closed, the piston returns to the top of the cylinder by folding the funnel and it is a tact of compression. The compressed blend is then filled with a spark plug.
Then an explosion of air is produced that puts the piston back to the bottom of the cylinder with a large force, enabling the crankshaft to rotate. This is the kind of explosion or power, which is the main source of power and torque of the engine.
Finally, during the stroke, the piston is lifted again to the top of the cylinder and throws out gasses generated by combustion through the relief valve.

2 stroke engine dirt bike:
Unlike the 4 stroke, 2 stroke engine has three strokes united to one, meaning that the suction and exhaust are combined in the compression phase of the movement, eliminating the need for valves.
This is accomplished by allowing the suction and extrusion assembly to be integrated into the wall of the combustion chambers. When the piston goes down after the explosion, the combustion products come out of the chambers through the exhausted circuit. Combustion of fuel and air is simultaneously inserted through the “door” located in the lower part of the chamber. As the piston rises again, he closes the suction and pulls out. Then the spark plug “throws” the spike and the process begins again.

2 stroke vs 4 stroke dirt bike conclusion:
The 2 stroke bikes can develop twice as much power and create twice as strong a 4 stroke bike of the same volume. It is also significant that he has a greater relationship of strength and weight because it is considerably lighter.
2 stroke bikes are simpler and cheaper. 4 stroke bike engines are more durable than 2 stroke bike engines that do not have the proper lubrication system.
However, 2 stroke spark plugs last longer than 4 stroke bike engines. 4 stroke bike engines consume less fuel and are cleaner than 2 stroke bike engines, which in turn create an unpleasant smell. 2 stroke dirt bikes have considerably higher emissions of harmful gases due to the burning of oil in them. Two units in some zones can also cross the permitted noise limit.
