Great piston

Good product, fit right in.

Worked great, good people

Perfect fit, complete package all parts needed (gaskets). Bike runs like a top.

Great pistons blasters running like a top!

Great parts.

I installed the new piston, which went on great, but when I went to install the cylinder I realized the cylinder gasket they sent was not correct for my bike. It did not fit onto the studs and was missing crucial ports. 2007 Kawasaki KX85

Just bought piston kit and was everything I was told it would be.

94' YZ250. Three thumbs up.

Great kit and everything worked as it should.

Just what I need to get my 2000 cr250r up and running again.

Good part for bikes. Had this same part on my bike, it’s a great use.

Works just like it should...fired up first kick...my 06 Blaster is back to running like a scalded dog.

Piston's a beast! Pro-lite baby! Wiseco 100.

Perfect fit for my resleeved 96 yz125
