I know this mus be a rather idiotic question, but I cant find any offical answer to this and various searches (Google isnt always your best friend) have lead to people pointing to both sides of the coin. So I figured where better to ask than here?

So the stock pistons, are they cast or forged? I was under the impression they were cast for obvious reasons, but now I'd like to know for sure.

 

Pretty sure we're forged. Some else will chime in. =)

 

Your motor is all forged internals

According to the brochure, the stock pistons are forged. As fot the rest of the internals, I'm not sure.
