89 forks swap on too 87

(1/3) > >>

Mike Grant:
I was wondering if anyone could tell me if I  could swap an 89 KX 46mm front forks onto my 87 KX 500 without too much problems. I've read that front forks could be swapped with the proper triple clamps but I am not sure if I could use my oem front wheel / rotor setup. I was going to purchase a 89 KX250  front end if I was able to use my oem front wheel without any modifications. I want to keep an OEM style conventional fork to keep the bike close to how it was it sold back in the day.


Also curious if any one has found an oem style footpeg that will improve work on my bike without  a lot work...

Thanks Mike

It depends on which version of 89 forks you are wanting to use, US or Non US.
The US didn't get USD forks until 1990.
The rest of the world got them in 1989.
In the mean time check out this link:

I have fork sizes, axle sizes, bearing sizes, hub sizes ect so you can compare.
All that being said, you could get a complete 2015 kx450f front end, get a new steering stem from EMIG Racing, and bolt the whole thing to your bike.
Can you say Upgrade?  :-D

..blasta he wrote that he wants to use the us 46mm kayaba conventional forks...   :wink: 

mike grant, all you need is the fork and the 89 brake caliper ... fitting it to the 87 is like playing in the sandpit...  :wink:

i use on my 87 kx250 the wp "extreme" 50mm forks from a 99 husaberg fc501. is a little bit heavier weight than the 89 euro-usd-forks that i used before, but an excellent performance ... sandblaster knows this build...  8-)
here are pics.. first the 89 41mm usd fork


and with the conventional wp- forks..

I would love to go that route at some point!
I'm pretty sure KXDINO has been testing them recently...I'd love to hear his thoughts.
