    Nils would be the man to talk to about this.....I can tell u that rotax maintains less than 1 gram difference on the piston,ring, pin, and rod combo. I have checked 12 of them all at 1 time, and if I remember correctly they were all at 1263-1264 grams for an entire rod/piston/ring assembly. I would imagine the CP's matching the stock weight, although they are surely better than the stock Mahle piston.

    Thank you, ill try to find Niels then. Yes I think the CP's are a good choice. They can handle a lot of boost even though i raised compression a bit from 8:1 to 8,3:1 with the 2 layer Rotax Racing gasket. They are on new Carrillo's and now ill have to ballance the crank to match it.
