2T vs. 4T | Which is the Best Small Bore?

When it comes to fun on a motocross track, it's hard to beat the KTM 150 SX two-stroke. The little bike packs a hell of a punch and is an absolute blast to scream around the track on. But how does it stack up against the KT 250 SX-F four-stroke? We wanted to find out! We slapped FMF Racing high-performance exhaust systems on both bikes and headed to Glen Helen Raceway with our pro tester Pat Foster to see how the little bikes stacked up against each other!

KTM should've kept developing their 200 2t, so many people loved that platform. That being said, The development of the 150 2t motor along with the advancements in chassis design eliminates any advantage the old 200 had. I'd like to see a comparo of the 300 2t vs. the 350f, which is where it seems a lot of us average vets are at.

Thanks for the vid Swapmoto, I think it can be also interesting a comparative between 250 sx vs 250 sxf... wait for it
😀

you can maintain the 150sx motor for two or three seasons for the cost of a single rebuild of the 250sxf motor, not to mention blowing up a two stroke does not mean you just threw $3, 000 down the drain

My 150 was my favorite bike I ever owned.

I need to decide between a 23 350xcf or 300xc as a first bike for open trails, woods, desert.
Track time on street bikes….
2t or 4t…that is the question.
Light and agro with the 300, or stable at higher speeds with the 350 4t. Your thoughts. Is there a maintenance difference or upkeep to consider?
I’m meticulous on oil and cleaning.
Not racing.

Glen helen probly not the best track for the 150. Now if the old milestone was still open...

[maverick]

So 4t still need a CC advantage, I think the question is answered.
