I am looking at putting a top end in my bike this and looked up the cost of a replacement OEM piston is ~$400. Is the OEM piston kit worth it or should I look at something like a Wiseco. I have about 30 hours of hard mx on the bike.
The Shop
Someone on here that is a mechanic or works in a dealership (don't remember) said he put Pro-X pistons at the top of his list in terms of quality.. They are also one of the cheapest, at least around here.
"Cast genuine 4 stroke pistons are used in relatively low performing engines like the Honda XR400R or Yamaha XT600"

For some reason I thought we were talking about real racing bikes where your link says "motocross and ATV applications use forged 4 stroke pistons as the cylinder pressure has risen. Forged genuine pistons are stronger, the alloy is pushed under extreme pressure to a form."
Heres an fc350 piston that is cast from prox.
Only downside with forged, is that i have not been able to find 3pp like Wiseco with different sizes. Seems only cast is available in "A,B,C".
Anyway we both talk about the same thing, modern 4-stroke mx bike pistons are almost always forged whereas 2-stroke pistons are either cast or forged depending on manufacturer. I know a link was posted above to a site which claims to sell cast FC350 ProX piston but I wonder if that is true since ProX piston catalog only lists forged piston for FC350.
