piston questions

i noticed wiseco only makes 11:1 pistons for a 300 and only 12:1 for a 250x. my question is are they the same piston and just the different stroke effects the compression ratio? thanks

none of the kiddies know...

i would think that a 250x piston would be smaller than a 300ex?

:rolleyes: the bore size on both is 74mm....

same piston size, but the stroke is smaller in the 250
