"250" horsepower #'s

"If you look closely you will see three different KTMs represented on the dyno charts: the 250SX two-stroke, 250SXF four-stroke and 150SX two-stroke. We included the two-strokes because both are legal in the same class as 250F four-strokes (under amateur rules). The numbers are spectacular at some points on the curve and dismal on others. Make no mistake about it, a 250SX racer would holeshot every 250 race he enters. The power is abrupt and violent, with a vigorous kick from 7000 rpm to 10,000 rpm. If you aren’t into being like Mike, or Ryan or Chad, the KTM 250SX provides a massive advantage...if you have the talent to take advantage of it. "

its funny how much higher the rpm's are on the 250f's 4 strokes to make the power "because they're the future" where the 250sx sits just over 8k to make peak

Buried under those numbers is the torque required to produce that higher horsepower at any given RPM.

Whatever it is, it is way to close to the 450's by looking at lap times this year.

I'm thinking we should go to 450's and 125 two strokes to get things a little further apart.

It's funny how you think equal displacement should mean equal power

I would rather have a 250f over a 250 any day of the week and twice on Sunday.

i am the same,

and most of the people that race in NZ, Australia and in the US amateur races agree with us, because they are all able to choose which bike they race, and mostly, they choose 4 strokes,

So, you're admitting that the 2-strokes have a huge power advantage in the amateur classes but yet you're STILL bitching about 4-strokes? This helps you're "rage against the 4-stroke machine campaign" how? Are you literally fucking retarded?

Do NOT let the air out of this poor guys fantasy by bringing up facts like torque and ride-ability. What's wrong with you?

Someone outside of moto once asked me to explain the difference between a 250 2-stroke and a 250 4-stroke.

This is what I told him:

-A 250 4-stroke makes about 10HP less than a 2-stroke, while the actual size of the engine is twice as big.
-The 4-stroke weighs 5-15kg more and costs around $2000 more.
-They are nearly impossible to work on yourself.
-They are about half as fun as a 2-stroke.

I ended with saying: about 3/4 of motocrossers ride a 4-stroke.

This is the response I got:

Hahaha, it's funny cuz it's true.

Also the OP link gives me an error, cant see it.

Edit: oh it's the "& # 13" thing screwing it up. Found it here.

They probably gave you that look because they knew it couldn't be 100% true the way you stated it; the whole world isn't as stupid as you perceive them to be.

a 250 four-stroke makes 10hp less than a 125? on who's dyno?


-They are nearly impossible to work on yourself.
"nearly impossible"; have you ever tried? I made the switch from working on two-strokes to working on four-strokes pretty easily (I can follow the directions in the manual; it must take a genius if this task is nearly impossible). It takes maybe an extra five minutes to pull the cams/head. Ever tried? It's really not that bad. I'm not a mechanic, just an average dude.

-They are about half as fun as a 2-stroke.
I'm having at least twice as much fun on my four-stroke. It's easier to control, I can then have more fun with it! I can do more jumps, and I feel safer doing it. I have so much more fun, that I sold my two-strokes and I'm not going back. So something like "fun" is hard to quantify, as we all have different ideas about what's fun.

...which says a lot of people are having similar experiences to mine.


Your friend probably gave you that look because what you said sounded just about as unbelievable as it is.

People aren't as simple and stupid as you perceive them to be. A huge number of us have tried both, and made a decision based on what we thought was more fun.

^ Why would he be talking about a 250f vs a 125 as far as power output? I assume he was talking about 250 vs 250

The Kawasaki is never out of the top 3 at any rpm range. Sweet engine.

Wonder how reliable that Kawi motor is though? Nice power it peaks at about 13k which is crazy most of the other motors fall flat by 11k.

While I would take a 250 smoker any day over a 250F..I do see why people like 250F's

They are easy to ride and for most, are the perfect balance of rideability and horsepower. They are making close to 40 hp these days!!

250F's are alot smoother than 250T's and easier to hang on to after a long moto.

Those guys making the electric bikes are modeling there bikes after 250F's (30-35HP) range for a reason..its optimal.

A 250-2 makes about 10 HP more than a 250-4. I take it you didn't read the story to get an idea about what the guy you jumped on was talking about. While we're at it, a 250-2 makes around 10 ft/lbs more torque than a 250-4. Let me put it into perspective for you and of course it assumes 100% equal riders. A box stock 250-4 with FI and a state of the art F1 inspired engine will not beat a box stock 93' CR250 to the first turn. Add sand or an uphill to the equation and the 250-4s ass beating gets even worse.

I was talking about 250 vs 250. By Size I meant the actual dimensions of the motor. Have fun trying to take out the plug on a ktm 250f for example. You need to remove the fuel tank.

Why would you have to take the plug out? 4t plugs never foul...

Just stopped by the local KTM dealer and asked how long to get me a new 250sx, He laughed and said put down a deposit and you may see it before the end of the year. No 12's it would have to be a 13.

Sounds to me like yes we do have a choice and the 2 stroke 250's are selling out. They need to make a crap load more because all the brain washed 4 strokers are starting to wake up.......
