In short the design and the inner working of a 2-stroke vs a 4-stroke allows a 2-stroke of a similar size/weight to make a lot more power than the equally size/weight 4-stroke. The downside of this is that it's a lot more polluting and a lot less energy efficient.
The reason they are faster than a 4 stroke is because the 2 stroke is for racing. The gas and oil are mixed together to make the ultimate engine for your MX. A 4 Stroke is mainly for Trail Riding in my opinion.
^^ this is only true for little bikes like 85s and 105s...
In real bikes 2 strokes are still faster CC for CC, they are lighter and the engines are more efficient for making power (fewer moving parts).
HOWEVER, the AMA has allowed for 4 strokes over twice the displacement to race against 2 strokes, for example a 450 4 stroke vs a 250 2 stroke, in this case the 2 stroke has no chance.
If the AMA were to equal classes, and the 450 were against a similar sized machine like a 500, the 2 stroke would dominate like the old days!

Is a 125cc 2 stroke dirt bike the same as a 250cc 4 stroke dirt bike?
im not sure about that but i can say that a 2 stroke 125cc is faster than a 125cc 4 stroke and probably 200cc too. a 125cc 2 stroke would throw you off the back if you cant handle it properly, where as the 4 stroke wouldn't scare the living daylights out of you
Is a dirt bike faster than a trailbike?
yes. you mean is a race bike faster then a trail bike. ya all racebikes are faster
Is a 4 stroke dirt bike faster than a 2 stroke dirt bike?
the 2 strokes have a lot of tourqe and a lot of speed ^^ Thats wrong, 4 strokes have more torque. CC for CC 2 strokes are faster for ex. a Yz250 (2s) is faster than a YZ250f (4s). But in classes, the 4 strokes have such a displacement advantage its stupid, a 250 2 stroke has to race against a 450 4 stroke.... as the old saying goes there's no replacement for displacement, so the 4 strokes win because of rules...
Is 420cc faster and bigger than 250cc dirt bike?
A 420 is slot bigger and is slot faster and also more expensive
How do you stop a four stroke dirt bike engine from backfiring?
More than likely you have a exhaust leak.Check the headpipe seal
Why does your 49cc 2 stroke pocket bike go faster than your 100cc 4 stroke pocket bike Is that right?

Which is faster crf450 dirt bike or yz450f dirt bike?
Every bike goes about 20km less than the cc's. So a 450 would go about 420km to 450km. Probably the honda. I dirt track a yz450f set up with 13/35 gearing on half mile track and get 70mph
