Maybe... maybe not..

Don't get that red stuff on the green stuff...
Mixing them together makes a greyish brown color...
Who wants that  :?

That triple is a 87 kx250 or very close to that year.
The Honda's were more rounded and the top clamp was black.

ok so will the cr 250 shocks be stronger did mine bend because they were intended for the 125  i cant see the 250 being that much heavier.  The 250 items look the same.

well ill be buggered lets see if i can find some of them does that mean my head stem is cr too??


after the pics agreed with sandblaster...  :wink:  

this are very good forks, but i think the 125-springrates are much to soft for your 250..also the double piston nissin-brake caliper is way better than the oem-one piston tokico that was used from 82-88 ..thats the reason why i fitted one to my 83 kx250 that also use 88-forks  :-)

your headstem is definetely kx125-500 85-88 . i have a complete 87-fork in my spares.
 conventional kx -forks from 83- 88 use the 43mm fork legs (same diameter as yours) so is for same diameter forks of other makes no diferent triple tree steering stem needed.

and after i showed my bike with the 89- usd-forks , you still ask of the fitment of the later usd-forks?   :-D

the stem-bearings kx125 /250 /500 are same size from 1980- 1991 (except: kx500 never changed untill the last year 2004)
kx125/250 became a new stearingstem with bigger bearings in 92.  now you have a big range of years and forks, where you can choose from.  :wink:

little kx-fork history
89/90 41mm usd fork (except us-models with conventional kayaba 46mm in 89)
91-95 43mm fork (kx500 91-96)
96-2001 46mm fork and also change to the newer nissin brake caliper (kx500 46mm fork 97-2004)
2002-2008 48mm forks in kx 125/250, kxf 250/450

and at least: here is what i realize at the moment a conventinal wp extreme 50mm fork (from a 99 husaberg fe501) to my 87 . in the next days i have to figure out, how to fit the brake. i think it ends up with making another handmade adapter like on my 83 kx250..

yes that helps heaps The reason i asked about the fitment is U say ur using 89 USD forks that are 41mm.  How will i fit them if i pulled out 43 mm shocks.  i have a set of 41mm shocks here from another bike that will not fit.  So to keep Kawasaki i need to go 91 to 95 shocks if i want to keep my head stem.  Sorry i prolly wasnt clear with all my frustration  :-P    So u used the 89 head stem on ur bike then? maybe I should read it all again got notes written down everywhere im confusing myself lol

i have a simple answer to your last question... how will you fit any UpSideDown fork in smaller diametered conventional clamps??
that could never work. the 41mm usd-fork for example is 50 and 55,5 mm in the clamp areas...
upside down means that the tubes have changed positions...  :wink:

you need the right triple trees to the usd-forklegs that you want to use . thats the reason, why i also adviced in my former post the fitment of the stem-bearings in the several kx- models over the years...
 thats the very important fact to know for the fork-swap ...
