I'm not sure this is 100% accurate.
Certainly there have been some reports of key wear among Kawai customers, however the exact cause is unclear, and may depend on the player's playing style or possibly even their individual physiology (e.g. the composition of oils and moisture produced by their finger tips etc.).

If you felt the need to replace the key surfaces on your second-hand CA65, that's perfectly fine, however I don't believe this procedure will be necessary for the vast majority of customers.

Kind regards,

While it's good to know there's a solution, it's a pity that it's necessary.

Yes that's the end result

I turned on the "linkfreigabe" option and I believe anyone with the link can view, you may try again?

Nah everything will eventually worn out, so that's normal I think? The CA65 is ~ 6 years old anyway, and I don't know what on earth the previous owner did. I deleted the picture of my old keytops so unfortunately I can't show you how bad they were, especially on the middle octave, and I was fine with it until it pull out dirt on my finger on some piece and that's so uncomfortable

Well everyone has, to some extent. Part of learning to play the piano (any piano, real or digital) is to learn washing your hands before playing.

I always do before playing my grand. I am less careful when it comes to my digitals...

Did anyone get a resolution to this issue? I have a note into Kawai about excessive wear on many keytops on my instrument. I have had quite a few pianos/keyboards over many years and never had this issue before. Cheers Mike

My CS-11 was showing wear at around 3 years, and I don't play *that much. I'm disappointed to hear it can't be polished out. I'd rather have a homogeneous plastic key that can be polished, but at least the keytops can be replaced.
