The difference is in the amount of stokes the piston makes in one cycle. A four stroke will explode on one stroke turning the engine over. Then on the up stroke it pushes the exhaust out. The next down stroke fills the cylinder with fuel. On the final stroke the piston compresses the fuel and the cycle repeats. This results in four strokes of the piston.
A two stroke has two strokes of the piston before it repeats the cycle. The first stroke is the explosion. The piston is pushed down. on the down stroke the piston reveals a port that exhausts, and then another port is revealed that fills the cylinder with fuel. the up stroke compresses the fuel and then the cycle repeats.
The logical difference is the 2 stroke will accelerate faster
i say that a 4 stroke is faster than a 2 stroke
2 strokes to many
A 2 stroke has a high pitch sound like a weed eater and a 4 stroke is deeper sound.
Mr poo
The engine, I believe.
the raptor is a 4 stroke and the bandanshee is 2 stroke
There is a difference between 2 stroke and 4 stroke, hopefully you know that part. yz250 is a 2 stroke, and yz250f is a 4 stroke. 2 stroke 125cc is the same as a 250cc 4 stroke. a 250cc 2 stroke is the same as a 450cc 4 stroke. so if you get the yz250, it will be ALOT faster then the yz250f, there different kinds of power. hopefully that helps.
A 2 stroke will require oil & gas mix while a 4 stroke will not. 4 stroke engines are usually quieter also. Check out link below. http://www.howstuffworks.com/two-stroke.htm
A 2-stroke dirtbike will be powered by a 2-stroke engine and a 4-stroke dirtbike will be powered by a 4-stroke engine. For the same power, the 2-stroke will be a lighter bike. For the same weight, the 4-stroke will be a weaker/slower bike. The 2-stroke is likely to use more fuel and make more noise. The 4-stroke will run cleaner and quieter.
4 stroke
As per my knowledge, There is no any 6 stroke engine in existance. The engines are catagorised as 2 Stroke and 4 stroke engines. The difference is 1)Suction 2)Compression 3)Ignition and 4) Exhaust (called power cycle) complete in 2 or 4 strokes.
Well the main difference between a 2 stroke and a 4 stroke is the firing process. On a 4 stroke you have 4, hence 4 stroke, intake, compression, power, and exhaust. As for a 2 stroke you have to combine them to get two basically. Generally 4 strokes will have multiple pistons with an oil reserve to lubricate everything but on a 2 stroke there is a point where the gas/oil mixture falls below the piston to work as a lubricant therefore one doesn't put oil in a 2 stroke.
