You’ll probably have to swap the triple, wheel and axle, just guessing.

You'll have to change all that plus the front brake caliper. Well worth the swap IMO.

Hi. Welcome to kdxrider.net. We have many threads on conversions.

Which model KX are you talking about? The KX125 / KX250 procedure is a slightly different procedure than the KX500.

Basically, you will need to buy:

forks
triple clamp
KX front wheel
KX brake caliper
KX front brake hose (or just get a complete KX front brake system)

Basically, it is not a fork swap, but a whole front end swap.

If you get a 2001 KX125 / KX250 set of triple clamps, the KDX stem will have to be used in the KX clamps. There are a ton of threads on here about this step, which is the trickiest step in the whole process.

On the model, which year KX parts do you have?

On the stem, it is pressed downward to get it out of the lower clamp. A hydraulic press is required, probably over ten ton press. A small torch can heat the aluminum a little to help ease it apart. If you think you are going to reuse that bearing, make an aluminum foil shield, multi-layered.

Measure the OD of the stem where it sets inside the triple clamp. If they are not exactly the same, the fit won't be the same.

There is a circlip to keep it from moving up. If you keep going, it will shatter the clamp. It only goes one way.

You will need to have the KDX stem knurled before installing it in the KX bottom clamp. You will need a knowledgeable machinist to do it.

The hole in the KX clamp is larger than the KDX stem.
