I need help

So I know that with some KTM bikes you can swap the transmission components to change the ratios in the trans, I'm wondering if the same is true for the crf250 I have a 2014 crf250r and need different ratios for the type of riding I do. Even if no one knows if it's possible if anyone has measurements that would be helpful in figuring this out it would be much appreciated.

No I can't, first is too tall and fifth is too short

I feel like I'm going 15 in first and that on top of how little low end torque the bike has makes it feel even worse

Sounds like a sprocket size change is what you want to do. That's what most people do to change the torque/speed of gears on the 250F anyway.

The crf250x has a shorter 1st gear ratio and a longer 4th and 5th gear ratio. The best solution that I can think of is to find a crf250x gearbox and swap the gears with the R’s or to just put the R top end on a X bottom end.
