Never really liked 250 two strokes, always rode 125's until about 5-6 years ago and have been on a 250f since then. Looking into possibly getting a ktm 150sx or a kx250f (both '12). The 250f is about $500 more. I don't race much more, just turned 40 so maybe will hit up a couple of vet races this year. Was able to be competitive at local vet races in the past riding my 125 and 250f, so not too worried about running the small bikes vs 450's. I'm not very big, around 5'6 and 150lbs so not too worried about the 150 being able to pull me around, just worried I won't like it after getting lazy riding 250f's the last couple of years. Pro's of the 250f are that I know what I'm getting, it will pull my lazy old self around corners without too much work and there might be a little bigger market for it when trying to sell it. Pro's of the 150sx is it will probably have a higher resale value to those that are looking for that bike (not many around), sounds like those that have them have a good time on them, and maintenance that I can comfortably perform. Any input from those that rode both?

I like the 150sx, a good friend of mine has one and the bike is a blast to ride. It blows my YZ125 away, I am only 5'6" also, and it fits me quite well.

I've always thought a 150 would be fun but I think I'm to heavy (200lbs).. A 200cc jug will bolt right on if you ever had the desire..

If I remember right, there's more to it than just bolting on a 200 jug. There are a few threads about it on KTM Talk.


Regardless, the 150 gets my vote. I'll admit right now that I might be a little (or a lot) biased. My 2008 144 was absolutely the most fun bike I've ever ridden and I wish I never sold it. As far as starts go, you'll have no problem grabbing good starts. I'm looking for another to replace it.

A guy in New England rode a 150sx in the 50+ vet class and had great results, even against bigger bikes at southwick with its deep sand.

I did sorta pull that out of my ass.. How about this.. The bolt pattern for a 200 jug is the same and the upgrade is common and relatively inexpensive.

pretty sure you need the 200 crank too.

Of course I would get the 150sx regardless of your skill level. On the 250F side, I actually don't think they will grenade if they are ridden easy and maintained well, but I haven't ridden a 250F or a 150sx.

250F has a broader power spread(read lazy Smile )and the 150 has to be ridden. Love our 08 144SX more than my lightweight YZ280F. More fun to say the least and that is what it's all about.

And I've had the $2200.00 and $2400.00 blow ups on the YZ250F and CRF250 and both were well maintained low hour bikes.

Wow, you have to wonder why the 250Fs grenaded. I had an XR250 (96) and XR200 (01) that I completely ragged out. They both still ran like a top when I sold them.

I have a 2011 150SX and it is by far the most fun you can have on a dirtbike. You have to really ride it and can't be lazy but it will guarantee a smile every time you ride it. I also have grenaded a 250F and parted it out as it was a better deal than fixing.
Just sold the 450 after $1400 valve job and topend etc. and bought a 250SX. All 2 strokes now and having more fun than ever.
Plus I can do my own rebuilds.....at $150 Smile so I get to ride even more.

Man, why don't they make them where they rev at a lower RPM? I guess the factories are making money with the top ends. I can't imagine why anyone wouldn't get a 150SX. IMO it is simply the perfect bike.

While I am a two stroke fanatic myself, this normally wouldn't happen to a properly maintained 4 stroke.
Valves will normally only snap off like that when there are worn valve train components. Basically what I'm saying is - if you buy a 250F thats a couple of years old, you better be prepared to rebuild every bit of that valve train from valves, valve guides, valve seats, valve springs and retainers, timing chain.. the list goes on.... or risk the picture above.

I can't see why anyone would buy a used 250F. Like baja and Newmann have said, even a well-maintained one will grenade.

This argument is so old but so true - less moving parts, less cost, less weight, etc. on the 150sx (2-stroke) vs the 250F (4-stroke). It's a no brainer.

I prefer my RM125 to my old 2011 KTM150, dont really know why.

But having said that id pick the KTM over the Kawi 250f any day.

It was purchased new and was quite well taken care of. While it didn't have an hour meter, I would bet no more than 20 hours time when it all went to shit. I was new to the 4 stroke game and just figured it was a shit happens moment. Tried again when the CRF250 came out and probably had less than 15 hours time when it had a freak oiling failure and cooked the entire crank/piston/cylinder/head/cam/valves. No need for a third one to scare me off of any more 250F's. Seems to be a common sight with the 250's, not so much the 450's.

Here is my souvenir from out 09 KTM 144SX 2 STROKE..... this was the 3rd time in 1 season.
KTM did pick up the final bill on the last blow up, and replaced the entire engine at the cost of $4600.

They can all blow up......... We've had 11 4 stroke bikes since this ktm, and have never had an engine problem with a 4 stroke.(Yamaha's, Suzuki's and now Kawi's)

KTM footed the bill for that? Sweet. Doubt Yamaha or Honda would have done anything for me but then again I didn't ask them to. Just move my money to something different. I'm sure they won't miss me.

I had an 04 CRF like you. I loved it, but it was my first bike after being out of the sport for two years. I only had valve issues., but that was very common with the 04-05.

Wouldn't buy another used 250f though, its just too risky.

If it was my money I'd go with the 150. Those new kawi's are super fast, but a guy here has had issues with his 2011 forks, and is seems pretty common when he dug a little deeper.

They did after I paid the first 2 times and provided the reciepts. They inspected the parts and decided it wasn't anything I did wrong and decided to cover the 3rd blow up.

$1700. Not so common or relatively inexpensive.
