The engine, I believe.
the raptor is a 4 stroke and the bandanshee is 2 stroke
A 2 stroke has a high pitch sound like a weed eater and a 4 stroke is deeper sound.
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
No difference.
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 four stroke has a timing chain and a cam and a two stroke doesnt a two stroke has reed valves
A CRF250R is a 4 Stroke bike.. And the CRF250X is a 2 stroke. E.g one has a power band and the other does not
i say that a 4 stroke is faster than a 2 stroke
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.
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.
RADITOR * Small generators either air cooled or water cooled 2 stroke. Autos are mainly 4 stroke and the majority watercooled.
