Front Fork KDX to KX - need fast help

[Midhigh]

I have an opportunity to P.U. a set of 1999 KX 500 front forks, Triple clamps, and front wheel assembly(bearings, spacers, axle, and rotor). Front brake caliper is the same as the 1996 KDX 200.

Any reason why these wouldn't work for my 1996 KDX 200?

The top bearing is a different size. So you will need to press out the stem, press your stocker into the lower clamp and then use a spacer for the top clamp between the stem and upper clamp where it comes through.

I see you are ebaying it up here!

is there any reason the 96 forks would not fit on my 89 kdx ? would this be a worthwhile swap? my forks on the kdx i just got have play in the bushings and need seals and dust seals

its funny but on my KX200 I took the 94KX125 up side down forks off and put on some 1989 KX500 46mm convetional forks
the 94 forks had to much stiction to work in the woods

IT is all about setting up the suspension. Most likely those bushings were worn and not replaced inside the units. Also running to thick of fork oil cause problems that could be stiction if you dont know the oil is to thick!

Racetech makes some teflon bushings for the inner pistons to help when the stockers get worn. Also running light 5w fork oil and if that does not help a racetech delta or the lower end gold valve makes the forks really shine! THe inverted units do not have the fork flex like the conventionals which makes ruts, turning and jumping much easier and predictable.

With any fork swap, you should disassemble the new to you units and replace any worn parts. Study the fork oil weight and level requirements and get the proper rate springs. Then tune the suspension FRONT AND REAR once you get everything together. The bike only works as good as the mechanic and tune of the whole unit!
