Comparing is not arguing and they ARE just having fun. However, both guys thought the 150 was more fun so the comparison proved its value.

[@powerhouse1981]

2 stroke weighs about 30 lbs less , mixed with the flicky, twitchy power, it makes it feel really responsive and jumpable. That's the benefit and fun factor. Also pulling around 30 less pounds for 6 - 8 hours is really nice, especially when trail riding and dealing with hairy situations. Have an Rm 125 bored out to 144.

[@lottolinks6394]

Ama switched for company profits and that's all. everything is twice the cost on 4T,heavier makes no sense

[@Bryankimsey]

We have both, except in '19's and we like the 250F on the track and LOVE the 150 off-road. We've got the tank from an XC on it and it is a blast in enduros, hare-scrambles, etc. The more flicking and weaving you have to do, the better the 150 is. A guy on our minute at the last enduro did Day 1 on his 250f and then switched his 150 for Day 2. We lined up and all four of us on the minute on Day 2 were on KTM 150s. But on a motocross track... the 250F sure tracks thru the corners nice and that equals faster lap times. Totally agree on the "control" aspect mentioned here.

[@1973f]

I raced against Pingree in 1985-1986 on KX 60s. He was in on a different plane entirely than anyone else in Montana back then. Insanely fast, nobody even came close to keeping up with him. Pure talent and an excellent rider. We all knew he would be a pro.i remember in Great Falls Montana he raced 60s, 80s and 125s and won every race.

[@Rubeless]

That was a legitimate evaluation. The pros and cons left out were cost and maintenance. Jody said it best about a two stroke “I can work on my two stroke with a butter knife”. If mommy is paying your racing fees, go 4 stroke. For those like myself a 250 two stroke is the best way to go. Excellent video gentlemen, I’ll look for the other with the built up 125. I love my bone stock yz125! In the 40+ intermediate class, if the track isn’t sloppy, I’m not losing due to the bike and most guys are running a 450.

Cool comparo! Loved the YZ version too. It would be very interesting to see how the 250 2T and 4T compare - from what I've seen the two stroke doesn't produce THAT much more power than the four stroke in the 250cc displacement. Great point about ease of riding, I am 61 and ride a YZ125 and love how I am not always behind the bike. With my mediocre skills that counts for a lot.

[@connorbrxy6556]

A 250 2 stroke does definitely have more power than a 4 stroke 250

[@weesmokeythe2strokey352]

The 250 2t has a little more power but alot more torque, that makes it "pull" alot harder but the 4t revs higher allowing you to pull a lower gear for longer giving it a mechanical advantage and has smoother power, that being said the 2t should pull away slightly but the 4t may have more manageable power and be easier to put the power down, that's my opinion and I'm a 2 stroke fan

Growing up riding banshees on the street , I always felt like hitting the power band was like a nitrous scene from fast and the furious 😂😂

I grew up on 2 strokes, now I have a CR125, YZ250F, and 350SX-F.... hard to pick a favorite. My YZ250F is almost as light as the CR125, and just feels like it has way more power... with the CR I bog out a lot because it has to be ridden wide the fuck open all the time. The KTM is a lot of bike, about 25 pounds heavier than my YZ, it's a blast and I know it has the power to chug me up any hill, but I have to respect the throttle and weight of the bike more.

Great comparison review of these 2 bikes. For my money, I wish KTM was still making the 2-stroke 200 - probably the best all-round displacement for enduro / technical fun riding. The 150 is too close to a 125, and it lacks a little on the bottom end. I would be interested to see your lap times on a 125 compared to the 150?

[@manoliswec5674]

200 was a mess for technical terrain. all the power of the world in 100 rpm range, you got to be 1 gear up all the time. its an 125 with bigger cylinder so not a clean sheet bike, i would go for a bata 200 instead even though i love ktms (except 200). 200 was great for mx. for enduro you had to put a sx 200 exhaust to make it ridable but it leaves small clearance on the rocky trails... i had one switch to 125 and im a happy rider!!!!

150 vs 250. That tells you immediately which is the better design. If your car has a 1.5L engine and you can run with a 2.5L, the smaller one is just a more advanced design. But we know what happens when they're allowed to be on equal footing. 4-strokes were the standard until the early 70s, when the 2-strokes came in and seal-clubbed them.

[@IBOO57]

It has nothing to do with a 2-stroke being more advanced. It's simply because a 2-stroke has twice as many power strokes.

So how would a 150cc 2 stroke compare to a 150cc four stroke? That is the true reality of the matter, this arbitrary cc handicap (and it IS a handicap) placed on two strokes is nonsense. Compared equally, cc to cc as they rightfully should be, there would be NO comparison. Less moving parts, better power to weight, less rotating mass, less expensive to maintain and build.....two strokes are superior for pure performance off road. If they had been developed with the resources, time and commitment as four strokes had been, they could be so much better right now.... just imagine. We have been done a grave disservice by the AMA, with this ludicrous handicap placed on 2 stroke race bikes.

The 125sx feels like it has more bottom just cause it’s on the pipe so quick, even though it probably has less.

2t is for real riders

Why are they comparing two bikes when the Porsche what's 100 cc's bigger? Want to take him pair of 250 4 stroke to 250 2 stroke since four strokes sold good?

[@aydenswift6327]

I might be wrong but the two stroke makes more hp

[@drunkdonkey1009]

Go with the 250 xc or 250 sx

The Ktm 125 is more forgiving because it stays on the pipe better.

[@josephbuczek9949]

Did you mean 150? or 125 for certain? im presuming the 125cc would stay on the pipe better and thats why id rather a 125 cc over that 150cc ktm sx However i wonder if the 150sx would be better on a trail ride than a 125 sx on a trail ride, if your not always doing just motocross? weighting in at 140 lbs a 250 never interested me the 125cc was always the right feel for my taste . idk about this 150sx would be the same, the 125s always had more speed than i ever needed but yes aggressive shifting required but thats the fun of it
