will KH moments fit on my K1 white widow?

ok i have an '06 (or so) koxx one white widow with standard 125 Koxx cranks. after trying out a friends uni with 135’s i really like the extra length and was wondering if i would be able to swap out my cranks for a pair of KH moments?

the reason i’m asking is that i know that for along time koxx used “ISIS” that wasn’t true ISIS. did i buy my uni before or after they switched to true ISIS?

if it is still the old “ISIS” am i going to have to replace my rim in order to get longer cranks?

as far as i know koxx is still not true isis. if you want longer cranks koxx has cranks in 135 and 140
