250r pistons, the bests and the worsts

[MathGSR98]

I need a new piston and I'm wondering which ones are good and which ones to avoid. I saw on ebay an ART cast piston. It looks like it's made by sudco as well as JE and Vertex pistons. Are cast pistons good for a 250r? At 29.00 usd + shipping, I find it really cheap: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=004&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=140041620576&rd=1&rd=1

What about Pro-x, Wiseco and other pistons? Any expert in pistons in here?

Thanks

Not much experience with em out side of OEM, but from what Ive heard on here, Wiseco or Pro-X are the way to go.

pro x are a exact replacement for OEM if your not boreing!!
If your boreing go with a wiseco there better.

ART is the stock 250R piston. I prefer Wiseco's myself.

I have a wiseco in mine. Wiseco pistons expand a little more than the others so the need to be well warmed before givin er or they will cold seize. I cold seized a new rebuild on my jetski this spring with wisecos. Replaced them with pro x.
