Perfect fit

Wiseco Piston Kit

Comments On Jul 21, 2014:Excellent product as always. The only bummer, the KIT didn't come with a wrist pin. Make sure you order a wrist pin. Great compression, fits right in. No issues and the bike loves it.

Great product, would buy again

Comments On Jul 10, 2014:I bought this piston because my old pro-x piston was at the end of its life and it seems to run much smoother than before. I totally recommend this product!

Wiseco Piston

Comments On Jun 13, 2014:I don't use any other pistons, especially for a 2 stroke, since Wiseco are the only brand that make forged ones for 2 strokes, and I would never use a cast piston!

High quality.

Comments On May 28, 2014:Not sure why some internet "couch racers" talk bad a bout the quality of these. I just replaced an oem cast piston that shattered and crumbled in my cylinder. This machined piston is top notch. Can't beat that fresh top end feeling!

Tough as nails

Comments On Mar 16, 2014:Have 7 years on the Wiseco that's in the bike now. Only changing due to new crank installation. I guess 'reliable' is the word I'd use.
