If I buy it, it'd be to flip it.
but I know I'd want to keep it.
I found it really hard to ride....kinda all or nothing, a lot harder to ride than the yz 125 and also like most ktms it vibrated quite bad and forks were harsh.just glad I got to ride one first!

I kept hearing about how much fun everybody was having riding their two-strokes, and the 150SX was my way of finding out if I was missing something.
In my first ride I was surprised by the narrow the powerband. A pipe and a silencer from FMF helped tremendously in broadening the power, making the bike much easier to ride. After a few rides I was feeding the clutch almost every corner, which helped me gain back some of my speed.
Maybe I'm just not talented enough, or maybe I just got spoiled by how good the current four-strokes are, but after six months I decided to get another bike.
The new bike was '13 SXF350, and after several weeks I realized I was rarely riding the 150 anymore. On the 350 my lap times went down, the big jumps became fun again (instead of do or die on the 150), and I could ride for much longer without getting tired.
I'm sure the 150 is a great bike for many people, but if you are considering one, I recommend taking test ride before buying it.
It was one thing after another with mine and I am super anal about maintenance!
It lasted about 4 months from new and totally ate the bottom end on it. Got the work done and got rid of it!
As far as how the bike fit me was the one thing I really loved about it! I felt right at home on it the first ride. But reliability far outweighs fit when I can take any jap bike and make some ergonomic adjustments.
150 could have some more power while the 250 2 stroke I cant relax and ride, I have to pay attention constantly.

In the same boat, and just cant decide on a 150sx or not. Problem is I cant find anyone that has one to have a ride on.
Currently on a 450f, and have owned a 125 before which I did like, just a wee bit frustrating on soft track or hilly terrain.
Anyone want to convince me either way? I think ideally a 250 2t would be the best option, just being completely honest, I just don't have the skill to ride a 250 smoker, it rides me instead.
I do love my 450, but with another baby on the way, the thought of a big $$ rebuild on a 450 puts the shits up me, need something I can confidently rebuild myself.
To the original guy, did you end getting one? Thoughts on it after riding for a bit?
I rode the 2010 model for a 120 hours and I didn't have any major engine troubles with that. Only major failure on my -10 model occurred when my chain got re-railed and broke engine cases from the mounting points. Fortunately the cases could be repaired by welding.
I have now about 40 hours on my -13 model bike and I like it very much. The -13 model engine is bit easier to ride than -10, but not as powerful. The newer frame feels more planted in the corners. I must be one of the few people who actually liked the PDS rear end of the -10 model. I think the KTM had the PDS system dialed pretty good before they dropped it. But with some rear shock re-valving and front fork oil height adjusting the -13 model suspension came out pretty good. The only engine failure with -13 model I have had is broken spark plug ground strip. Luckily it didn't made made any damage on my cylinder. I think cause of the spark plug breakage was detonation caused by too lean jetting.
I'm a bit of a clutch abuser and I have to replace the clutch plates quite often on a 150SX. Another thing u have to do with the bike is to check the engine mounting bolts and rear swing arm bolt torque after every ride because they do tend to get loose after time.
Do you like to really have to work the bike, clutch, shift, push your limits in the corners and use a lot of body english to keep maximum forward drive? If yes, you need one of these now! They reward hyper aggressive riding and are extremely forgiving when you get a bit out of control as a result of riding like a spaz.
If you like to let the bike do it's thing and click off fast, smooth laps you won't appreciate what it has to offer.
For every hour I've put on my 250 this year I've put 4 on the 144. I'm not fast but I fall into category A, and being out of shape I find the 144 is more rewarding and not as hard on my body. I've only raced the 144 and I've gotten better results on it than any bike I've ever owned, you can still get a good start on it if it's nit a really long power robbing start straight as long as you get a decent jump off the gate.
Simple and easy to wrench on, super light, fast, it's a very capable bike if you ride it the way it's intended to be ridden. The only place I think it leaves something to be desired is long uphills and big do-or-die jumps right out of a corner. It makes up for it everywhere else. You can brake later, get on the gas earlier, outcorner bigger bikes, and I find that I have a lot more left for a late moto charge. On practice days I can do more motos, longer motos, and I'm not as sore the next day.
There's nothing like the feeling of finally getting that jump right on a 125, though.
