Four strokes have a lot more bottom end power (torque). So they are only faster off the line and in lower gears. That is why all the pros have them. Because on a track, you need that instant power and you don't even get passed 3rd gear. But two strokes have a "thinner" power band (in the sense that its harder to stay on it), so when they get into higher RPM's, they hit that "power band" and take off. 4 strokes have a much broader RPM range for their powerbands, that's why they are torquier and have a more constant power feel to them.
2 srokes have powerband (response) and they rev higher = more power
For the same engine size, it should be.
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
i say that a 4 stroke is faster than a 2 stroke
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...
No. I have a 100cc kx 100 2 stroke and i can race 450's and beat them. 2 strokes are faster off of the starting line and in a straight away race, but after maybe a mile 1/2 the 4 stroke will win
A YZ250 is much faster than a CRF250r. The YZ250 is a 2 stroke where as the CRF250r is a four stroke.
Dont run it on 2 stroke fule.run it on a blend of metho and 2 stroke fule. Add 500mL of metho to 1L of 2 stroke fule and mix. use thise in your poket bike it will go 20km faster
Yamaha YZ250 hands down. Both bikes are designed for a different purpose. The YZ250 is a 2 stroke motocross bike. The WR250F is a four stroke enduro bike.
bore out the engine, make it lighter, and add nos at bis racing.com
yes iif u put a bore kit in it
It's a dirt bike that uses a 2-stroke engine.
