« on: May 01, 2009, 01:20:42 AM »
does anyone know if a set of forks and triple trees of of a 93 kx 250 will go onto an 89 kx 500 frame?? any help would be greatly appreciated as im trying to upgrade to the newer inverted forks.

Yes & No,

The trees and forks will fit but you have to swap the stem from the K5 to the K2.5 trees & have a bushing made for the top tree. Also keep in mind the K2.5 trees have less offset (which could be a good or bad thing depending on type of riding you do).

thanks for letting me know the forks are coming with the lower triple tree and the stem but no upper triple tree so i was wondering if my 500 top would work or would i have to get the 250 one and make a bushing, thanks for your feedback.

Turbo,
You need the K2.5 top tree also, the offset is different between the them.

The 93 forks are 43mm and too small for the clamps.

So you're the guy that got those forks I was watching on eBay? lol

I was thinking of swapping the conventional forks on my '89 250 with these '93 forks, but the auction had no top clamp, axle, or caliper, and I didn't know what all would swap over from my bike, so I left it alone.
