That's the one thing I dislike about the KFX really.

To me, a woods weapon should rarely ever cross neutral...

I like running higher sprocket gearing better... and 14/36 would be similar to 15/38... but just trail riding I cross neutral a lot.


For what it is worth, I tried the 39t rear for trailing and actually like it pretty good.
I don't think I'll take the 39t rear off...

Think I'll run 14/39 and 15/39 depending on where I am going and what I am doing.


I can't really explain it for some reason right now, but I like 39t rear better with 14t front... and like it way better than the 13/38 I would do occasionally for the mountain trails.

I can't think how to word the explanation.

Hey! Duster...Using a 39 rear do you find yourself more centered around 3rd gear in the woods...and using a 38 rear more centered around 2nd gear in the woods or tight areas...???

Well man... I look at my detailed gearing sheets with all specs and speeds....

And I can't really quantify what I am feeling from any of that.

So I can't really give an explanation with any sort of data like that.

In reality of the data, 14/39 falls about dead between 13/38 and 14/38.
It's closer to 14/38 than it is to 13/38 though... instead of 1/2 way down, more like 1/3...

However, the feel is not so much like either, which does not make a lot of logical sense.

To me, 13/38 makes the gear lengths even more annoyingly short, and it's only bearable for a leisure type ride. Try to get a little spunky with it, and it just pulls so hard it's like an arm stretcher. It's tiring and a hand full and loses a lot of traction in dirt.

But 14/39 doesn't really seem to do that. And somehow it really seems like it's an easier ratio for the engine to work with than even 13/38. Seems easier to put it in 1st and chug up a technical hill climb, and easier to loft the front end with a smooth motion to hop a big log. Yet it doesn't have that exhausting pull.

It seems to have more balls, yet delivered smoother.
I can't see an explanation for it in the data though.

I am going to try 15/39 next... I think I'll like that too for riding hard and fast.
