From reading other's posts,Wiseco is the most popular on kdxrider.net.

Beware of the cheap, no name brand piston. (eBay)

Also, I would skip whatever the cheapest name brand is, also.

Wiseco, Vertex or Wossner sound great to me.

Don't let them send you a Namura.

Measure before buying.

I have read a lot of people say Pro-X is made by ART, a huge Japanese piston company that makes a bunch of the OEM pistons. I would be OK with an ART made piston also.

Just take it apart and measure before buying. Someone on here in the past few months took his apart to find someone had made it a 240cc. I don't think he bought a piston before that, but it would have been bad if he had.

If it has not been altered, the cylinder has a coating (Electrofusion). It can be bored or honed. It can be replated or worse, a sleeve put in.
