KX or KLX fork coversation for KDX

17 posts in this topic

I have an 04 KDX 220. Have read a few threads about converting over to a inverted KX or KLX fork The KLX fork interests me because it would be easier to run the headlight which I like to have on in the woods - helps prevents head on collisions.

Anyway, as I understand I would need to get off ebay:

- forks, axle, front wheel , top tripple clamp - press KDX stem into KX/KLX stem. Brake rotor

Are the KLX forks shorter? I have heard that the KX forks are one inch longer and that could mess up the bike geomentry.

My question, is that for an 04 and given that I want to run a headlight what would be easier.

Thanks for your time and input. Steve

Money - somewhat - is not an object. A grand or less total for conversation. I got plenty of time. Good winter project.

Steve I don't think KLX forks are what you want. Late model KX forks would be the hot setup between the two. Unless you like beefy conventionals

Here's the place to go to get all your KDX fork swap info.:worthy:

Yup, that is the place to go.

I know very little about KLX forks, from what I have heard KX's are superior. For a headlight most people just buy a $40 aftermarket UFO twin headlight that mounts with rubber straps.

Yup, you need forks, triples, front wheel /axle and brake rotor from the same year of KX, newer the better. Press out the KX stem, press in the KDX stem into the lower KX triple (sometimes there is a sloppiness problem, read up). The only custom work involves the stem to upper triple clearance and spacing, not a big deal and can be remedied by shim/washers, or a machined spacer if you have machine shop capabilities.

You would be hard pressed to spend a $1000 on this swap. More like $400, then if you sell your stock stuff for $200, you will only be into it for $200. Some people have done it for more, some for less, it all depends on what kind of deals you can get on the components.

Check out kdxrider (you must register to get access to everything), you will read till your eyes bleed, I had all my stuff on order within a week of reading that site, so beware.....:D

I think you have a sweet setup there foots, I have been riding my buddy's RMX lately a bit, the forks feel real nice.

Quick question - KX 125 or 250 forks. Are they the same? I will look for 2000 - current forks on ebay. Any years better than others?

99-current is what you want, I think it goes 99-02, then 03-current as far as models go.

250's typically have stiffer valving and springs than 125's (but both are typically going to be valved too stiff anyways, the KX125 springs will probably be close depending on your weight).

Thanks !! I had a 95 RMX and never could get a handle on the USD forks on it. My DRZ made me a believer in the 49 Showas. Heck if I can get them to work good on that overweight hoss I figured they would be a dream on the KDX. This set was sitting in a corner collecting dust anyway. I think some flex is needed offroad. And I assume Scott Summers does too as he ran XR conventionals on his CRF450 when he tried a comeback.

My buddy's RMX is a 1997 with conventionals on it, do you know what size they are?

Found some 04 KX 250 4 stroke forks on ebay. Are they the same as the 2 smoke forks? Would they work for the KDX conversation?

Conversation or conversion? he he, just giving you a hard time.

I have heard they will work, but don't know the specifics.

Obviously "conversation." Everyone seems to be talking about it here... :worthy:

I figured it out, 46mm Showa conventionals. Foots, your 49's must be massive!

I absolutely love my KLX fork conversion and it worked beautifully with the headlight, I night ride all the time. I'd go for it if I were you
