The Wiseco RC813M09600 piston for the 2008 CRF450 is significantly better than the OEM cast piston. Box forged, shot peened, nice skirt coating, dlc coated pin and Ti Nitride rings.

We use CP but the Wiseco RC series is a really good piston and I would rather run it than the OEM piston.

I'd say they are about the same, the OEM Honda pistons are pretty good. However if you want more compression, or DLC pins, or any other features, go with the Wiseco. I use JE which is a slight step up from Wiseco or you can use CP but I don't like their Honda 450 forgings, it is a bad design IMO.
