i had them on some 06 k2 seths if that helps at all. the waist is 100 on those and they easily clear by more than a cm on each side... so i think they are exactly 120
this years have a toe height adjustment, other than that these are the same as far as I know...mounting pattern hasn't changed so I have no clue what the "power width" you are talking about is. All jesters have a wider than traditional binding mounting pattern to help drive wider skis
