Last week I spoke with a local machinist who caters to the motorcycle market. He claimed that Cast pistons (Pro-X or Stock) are a better way to go then Forged pistons (Wiseco). I know Wiseco pistons are very popular for KDX's so I was surprised to hear this. Can any of you verify whether or not Cast pistons are the way to go?
