Howdy folks. What would it take to fit the Showa SFF TAC forks off my '15 Kx450 to a 04+ KX 125? Would i be able to just swap the whole front end over? Do I need to swap the steering stem?
Thinking about getting kit forks for my '15 KX450 and would like to keep and use the TAC forks for the pinger.

Valving and pressures will be much different.

Front brakes do not need to be swapped. I believe your '04 has the "CR style" front brake line routing, so you will not need a new line. You will need a front axle and wheel spacers from a new four stroke. Your 125 front wheel will work.
On the '15 KX450f:
-Fork OD at bottom clamp : 59.XX mm
-Fork OD at top clamp : 53.XX mm
On the '04 KX125
-Fork OD at bottom clamp: 59.XX mm
-Fork OD at top clamp: 55.XX mm
Wondering if i can just swap the top clamp of the '15 Kx450 over to the stock '04 KX125 clamp and be fine? pretty sure the forks are the same distance apart on both bikes.
Might be too easy. Anyone try that?
I'll try it out tomorrow after work.
Is the offset of the KX250 clamp the same as the KX125? Perhaps a KX250 clamp has the same offset as the KX450f?
Wish all of the offset and diameter information was published somewhere for quick cross referencing and parts compatibility.
13+ KX450F : 23mm
03-05 KX 125/250: 25mm
The next closest i can find is a 09-10 stock lower clamp (23.5mm offset), but the steering stop posts are not the same style as the 03-05 KX so its the same situation as the stock '15 450 clamps.
Not looking good unless we can find an aftermarket lower triple clamp that's a 23mm offset, has the same steering stop posts as the stock 03+ KX lower clamp, and accepts a 59mm OD fork.
I was also thinking of contacting that ebay seller and asking what lower clamp that is.

Are you able to use the stock 2015 clamps as a whole set of triple clamps? If so, just remedy the steering stop issue and ride on.
An option is: Make a new steering stop for the frame and have it welded on.
Changing the stock steering stop on the KX125 frame means that i wont be able to use the stock clamps ever again.
DB97 do you confirm me that you are using fork with Stock clamps just adding that spaces? ? please tell me yes ??
Also, do you know the stock offset on the 2000 KX?
