Which Kawasaki forks were 56mm outside diameter?

Hey all, I bought a used upper fork tube clamp that was labeled as 95-06 KDX. My bike is a ‘95 H. The new upper triple has a 56mm ID. Which Kawi’s had a 56mm upper fork tube? This will determine if I do a fork swap to match the 56mm clamp or cut losses with the “new” upper clamp and get a stock one.
My original upper clamp is no good due to my stupidity with a press. Thanks y’all.

Good luck on finding an answer, inverted fork tube diameters are not well documented in any particular place.
If it was a KDX, it was a '91-'94 KDX 250 or '93-'94 KDX 200.
It's also likely that it might have been a pair of KX forks swapped onto a KDX, and the parts dismantler had no idea they were not the original forks and labeled them as the originals. Also could have been a pair of KLX forks, which are a direct bolt-on swap to a KDX.
I can measure my KLX forks as well as my '97-'04 KX500 (96-97 KX 125/250) forks possibly tonight or Monday if you need an answer. Post a picture of the clamps please, and also post a picture of any casting marks or numbers on the underside.

Whatever they were from, they were from inverted forks. I would suggest looking at the eBay seller's auctions for KDX forks and see what forks you can find photos of, including completed listings and sold items.

Thanks Chuck 78 for the info! Yea I was thinking it might be a long shot (I mean who measures the OD of their fork tubes?), was just hoping to narrow it down (which you definitely helped me with!) so I didn’t waste my new OEM bearing.
I’ll dig a little more and see what I can come up with. Would you be able to check your forks if you Chet a chance? Thanks!
