Will Cr125 swingarm fit to cr250? (1993s)

As title says, will swingarm from cr125 bolt on/can be used on same year 250?

Im rebuilding my 1993 cr250 and i noticed that my swingarm is fked. Side of the bearing housing is craked and some groves from chain..

I have my Cr125 1993 swingarm from my old cr, it looks same as 250 swingarm but part number and markings on it are different..

Needle bearings and swingarm bolts are same on both bikes so it should fit but i'm concerned about markings since i dont know if its weaker or something?

As far as I can see a lot of years are interchangeable.
1993 is not specified.

What makes parts weaker or stronger is welds, the way they are constructed and thickness of the material.
Not numbers on it.
I think if they are identical, they are the same
But ofcourse there are guys here who know more about this.

part numbers are
52100-KZ3-890ZA (250)
52100-KZ4-890ZA (125)

KZ4 is not available so I believe that they discontinued the KZ4 as it is the same as the 250, this confirms it as from your pictures both 125 & 250 have KZ3J stamped on them, rest marks maybe are production line numbers/letters.

personally I would use it but wait and see if any more info comes up!

The answer is yes, the two swingarms are identical and completely interchangeable.

"KZ4" is the model identifier for the CR125 while "KZ3" is the model
identifier for the CR250. In 1993, the CR125 and CR250 used the same
swingarm thus the "KZ3" marking but the "KZ4" part number. The CR125s
had a number of KZ3 parts in the mid 90s.

The other markings are modifiers, and internal codes. The "8" and
"9" refer to the months they were made and the "C" refers to the
Saitama factory and the "K" refers to the Kumamoto factory where
each swingarm was turned out.

Hey, sorry for the super late bump, but I was wondering if you ever managed to fit that CR125R swingarm onto your CR250R. I’m currently doing resto on a ‘94 CR250R with a cracked swingarm, but can only find ‘94 CR125R swingarms, or swingarms from different years. I appreciate any help and info!
