kf450f piston in a trx450

[big bad beny]

I got a buddy who just put a kx450f piston in his crf450. Didn't know if any one put one in there quad.

I know the 04/05 TRX piston is different then the CRF... I'm pretty sure the 06+ is different too... Wrist pin is a different size? I think?

ud have to check the bore size first, then the pin dia. then the pin to top of piston (comp ratio) also valve releifs would have to be the same size

I don't know if you can but why would you want to do that?
