Good article on motocrossactionmag.com comparing the YZ250 to the YZ250F. Sorry don't know how to create a link.

Talk about telling it like it is :P
-
Very interesting, almost all but said the yz250 was better, and the winner is :D
-
But we already knew which one was better didn't we :D

Yes, but the media never admitted it and now it has been revealed to the masses ;D

Interesting, they had a similar article out in 2008...

Similar, hell! It's like they took the old article, put in some new numbers and a couple of lines, and called it a day. I didn't know this whole recycling movement thing had already moved into the realm of recycling ideas!

Maybe they thought it was so good they wanted to share it again to reach more of the uninformed masses?? :D

I agree, but at least they are putting real world comparisons out there... We need to give them credit for that. I found it amusing that they had to dig down a little to find a rider who has raced with both 2 and 4 strokes. Overall I liked the article even if it was recycled, it gave ( I think) real facts about both machines. I agree with them that if an amateur who rarely rode a 2 stroke switches now they will struggle, (but they will have more fun doing it). I like the idea of different strokes for different folks. Pick your poison (strokes), lets line em up and have some fun.
-
I can understand the recycling... I've done it myself!
In this case when they originally published the article not many people were interested in the two-stroke. Now there seems to be almost a "revolution" when it comes to two-strokes. Many of the factory racers are talking about them and saying that they like them.. articles about old two-stroke surfacing, rumors of a Fall two-stroke series...
There is something happening here... you guys are at the forefront! ;D ;D

Yeah this is only a repeat to pacify the two strokers. Don't be fooled by MXA, they are practically owned by the Big 4. They will compare this but they won't dare compare a 150SX (or TM) to a 250F.
-
Why wouldn't they compare the 150sx to 250F? I didn't think the 150 was legal in AMA Pro racing anyway, has to be a 125. From the stuff I seen lately, the 150 seems to get the nod as one of the funnest bikes of all time.

If memory serves correctly, there was a test in MXA between the 150SX and the 250F... just don't remember the issue.
When asked they didn't shy away from the question either.

Additional info.. read this test.

A few interesting quotes;
Q: HOW DOES THE KTM 150SX COMPARE TO THE KTM 250SXF?
A: Compared to the KTM 250SXF, the 150SX is incredibly quick-revving and peaky. On the 150SX you can either scream or just putt, but you canâ??t cruise around. To maximize speed on the 150SX, the rider has to learn exactly when to shift, what gear to be in and to have an itchy trigger finger on the clutch lever. In a wide-open drag race against 250Fs, the 150SX actually wins out and gains inches. But any time itâ??s not in the sweet spot, itâ??s getting pulled by the thumpers.
The 150SX makes more horsepower than the 250SXF, but it gives up a little torque (18.9 ft-lb to 19.2 ft-lb). The broader powerband of the four-stroke and the extra torque make it easier to ride, while the hard hit and extra power of the 150SX make it a potent weapon in the hands of a talented, go-for-broke rider.
Q: CAN THE KTM 150SX BEAT THE KTM 250SXF?
A: Yes. It is an underdog, but the truth is that it makes more horsepower (albeit a lot peakier than a four-stroke), weighs a lot less (it is more than 15 pounds lighter than the typical Japanese-built 250F), is eminently more flickable (so much so that riding a 150SX is completely different from riding a 250 four-stroke) and can be repaired for a quarter of the price (should anything go wrong). The caveat is that not just any ham-fisted novice will have the skill or know-how to dance on the edge of the KTM 150SXâ??s powerband.
I have heard many complaints about MXA in the over 30 years I have been a reader. Some have a basis in truth and some are because the person talking about the mag, doesn't like it.
Personally, I think their bike tests have gotten "stale" with the Question/Answer thing. But their reviews of products and in-depth articles are fantastic.
Don't know where you got your information, but I know for a fact that Jody is a two-stroke fan.
-
The truth will prevail I would like to see the same test on the KTM their two stroke has a different rear suspension.
-
What I find most funny is that they are comparing a bike that has not been touched in a decade to a bike that is constantly updated, and the the yz250f still lost... :o

The 90's technology of a two stroke > 2010 technology of a four stroke
-

Now if only the free CC's that were given to four strokes were given to the two strokes. Hell, even 100cc's for the 450 (250) class, I'd be happy. Just the thought of a 2012 RM 350 2 stroke with the new frames/suspension/weight reductions, make me tingle, haha.

I reckon an extra 30cc on a 250 smoker would be ample i reckon, most of us normal people would still find a standard 250 enough of a handful, i know i do.
But the sound of an RM 350 two stroke, or any other for that matter does make me smile :D :D

I was thinking the same. 30cc would be close to enough to level the playing field, but with 100cc's the powerband could be tamed to match that of a 250, but give the torque curve of the 450 4's. A whole new engine, just like the thumpers got in the late 90's, early 2000's.
-
Well hell, we don't even need 2010 two-stroke technology to be competitive. Take an old 450cc engine, put that in a modern frame with modern suspension and brakes, tune it up a bit like any good racer, and I guarantee you'll be more potent than a 450F. Or, like you guys have been saying, something in the 350cc territory would do. And really, once you get above 350cc or so, if you're really on the powerband and doing your damnedest to give it all she has, no one's going to catch you on a 500 unless they have enough space to get into the higher gears. Their reward for extra cc's is going to be the ease with which they can fly around the track at warp speed. As many riders unfamiliar with the 500's ways have found out, if you hammer it and ride it like a 250, not only will you be putting your life in serious jeopardy, but you will also probably go slower than if you took it easy and lunged about on waves of torque.
-
Anything from 300cc to 360cc or so would be a weapon in the right hands. :D
Would be nice for one of the smaller companies to bring one out again.

Dare I say... Maico 320?

You may Jetz :)
Forgot about that one
