just passing along info i found out yesterday. '94-'07 cr250 clutch has oem steel plates in it that fit cr500. their .003 thicker than the aluminums but i dont know if that would matter. total combined with all 7 plates is roughly .021 thicker but it may work. part # 22321-KZ3-690

Gee.... I have an idea.... Why not just buy the correct CR500 plates in the first place?

500 and 250 share the same plates, but the 250 has 2 steel plates in the middle. if you wanted to run steel plates but didnt want to buy a complete barnett clutch kit because your fibers are still good, then you could just individually buyg these steels instead. they are slightly wider but the barnetts may be slightly wider than stock also and i really doubt .021 will matter but maybe so. anybody have a steel barnett laying around they can measure ?. these plates cost $65 for 7, a complete barnet kit is alot more than that. any of this make sense

No it doesn't.

When I need a new clutch, I'll just buy the superior Barnett instead of stock.

If U R running a cable it doesn't matter. Using a magura the extra thickness makes the magura not able to disengage 100% unless you shim the slave off the cases. Even then I had problems. Back to a cable and lubed often.

I one for steel pates they don't make you oil in you'r trany BLACK and leaving all that worn off Alum behide it the trany.
You will find after doing Oil changes you oil will be alot cleaner when changing it out and when you go into the motor lot less grim to deal with.
One trick you can do if you change out from alum to steel drain the oil put a Quart of Dissel fuel in the trany shack the bike around kick it over slowly DON"T start the bike drain the dissel out do this 2 or 3 times it get rid of lot of the grim out of the motor before you take it apart.
If you want you also can put 1 quart of cheep car oil in the motor shack it around to get the dissel fuel out before you put the good oil back in it.
I heard Alum plates do have a better gripping power than steel and lighter but I never had any issues using steels.

DON"T let the dissel fuel sit in the motor to long it will eat you seals up this is to be done one step after anouther not long term letting the Dissel fuel sit inside the motor it should only take 5 minutes for each flush cycle.
Unless you plannig to replace seals anyways But I still would not let sit in my motors to long just in case.

the honda steels are extremely heavy compared to the aluminums. i didnt weigh them to be exact, but you can easily feel the difference just from picking them up in your hand.
Weight

I don't care as much about weight of the plates I looking whats going to last with less mess That getting older and lazyer at least for me is the cause of this.
When I was much younger It matter how light and how fast I can make it I did not care how long the motor held together, not any more I just want to ride the bike with no worries I gotten to old to push the bike back home.

If you want to upgrade from aluminum to steel plates buy a set of steels from moose for a cr500 there 45 bucks for a set.
the difference in aluminum and steel is one the weight, two the aluminum warps when it gets hot and makes your clutch feel funny, three the oil stays cleaner longer with steels, and finally aluminum plates are desinged to wear before the fibers and the fibers wear before the steels. also steels last a really long time
