KX500 with Yamaha suspension?

[ben]

I have a 1992 KX500 and was thinking about upgrading the suspension components. 

I weigh about 215 without gear, 6? 1? tall, and I will ride the bike in vet mx/vintage mx. 

I was thinking about using someone like Factory Connection for heavier springs and/or suspension revalving, but then a friend of mine suggested possibly trying to put newer modern forks (or a new modern complete front end) on the KX500.  I have access to a friend's blown up 2003 Yamaha YZ450F that might be a good starting point.

Has anyone done this before?

Thanks.

My uncle has a 92 kx500 with ?hlins forks of a yz. There some pics here on the site of it, Red Bull Knock out could be a search link.
It works super, better then the stock forks. For mx it's perfect, for dessert you need a steering damper.
At 80mph or so it wil head shake to much.

DO IT . Let us know how well it works for you, & what you had to do. I "think" the dogbone will help that set-up even more.

X2 on the steering stabilizer,  tightening up the rake really makes them rattle the bars at speed. I need one before I eat it. Really small repetative bumps is where you'll notice it most, like wash boards

MOTORRAD  How did You get the 2008 KX450 suspension on your K5?   VERY INTERESTED

If you could figure out a way to use '06+ Yamaha Kayaba  SSS  "speed sensitive" forks on the K5, that would be a HUGE upgrade in plushness. Both my previous '07 YZ450F, and my current '08 YZ125 have these forks, and let me tell ya' they are AMAZING !  I believe the '06+ SSS forks are 48mm

That would be awesome too i'll have to check up on that thanks for the info. Also need somethin for the rear too

I wonder if you can piece together the YZ's 48mm top an bottom clamps to the KX500's  stem post ?
