On the prox site the clutch plates have the same nr but the clutch kit not
More, less or other springs... Or different metal plates?

For one of the plates, OEM is the same for one kind of plate, but not the other. It has a different part number. You may want to call or e-mail Premier.

I think they do interchange. As I recall the difference was the KDX, had heavier metal plates and stiffer springs, so the much more common swap was to use KDX plates in the 125 for more durability and a little more rotational mass.

The clutch plates are the same but the kits not, so there must be a difference in metal plates and/or springs
My clutch is on the end but I'm not going to gamble with a "maybe will fit clutch kit"
What is the result when I would install the kx kit so what is the result with less heavier plates and weaker springs?

Generally with lighter springs the clutch lever pull will be easier (maybe not noticeable though) and the clutch could have a tendency to slip under a load. Lighter plates means less retational mass so possibly a slightly faster re I guess bike (with clutch engaged). Again, how much you would actually notice this is questionable. The possibility of the clutch slipping would be my major concern.

Note I am basing my comments on building out a 175 to a 230cc many years ago and the problems we had with clutches then. We never satisfactorily solved the slipping problem hence the engine never put the power to the ground it was capable of making.
