Curious if anyone knows if the new 2.25 gallon tank coming on the KX327X will fit on the 2024-2026 KX models?  Could be a nice win for off-road crowd if this larger 327 tank can replace the stock 1.6 gallon tank that came on the previous models…

Only if you move the intake valves to the bottom of the cylinder!

Prolly need to wait until it actually hits a dealer floor. Have you seen an actual 327 yet? No

Maybe the 2027 KX450FX will work?

how could anyone possibly know the answer to this question? Not to mention the chances of a brand new EFI 2 stroke sharing the same fuel delivery system as the EFI four strokes is slim.....

Good catch.  I didn’t see that the 450FX got a new tank.  It’s only 0.3 more gallons, but it’s something and it looks good.

Will probably find out in late December of this year, or 1st quarter’27 maybe.

KTM does it so I don't think it is that slim of a chance. There may be more room above the engine on a 2t so it may get a bigger tank than the 4t because of that.

Are the 2026 KX250 and KX450 tanks the part numbers the same as the KX 327 part numbers? You can go to your local dealer and the parts person can probably answer your question?

I doubt the parts fiche is available for the 327 yet. I also doubt the tank is the same as the 4 strokes.

It will take some time for the aftermarket to get stuff built......bikes need to available for that to happen.

In the video with Stu Baylor he said it looked like the same tank setup as the 4 strokes but said he would have to actually pull it off to verify it.
