awesome product
This is the second piston I’ve bought of this brand for two different bikes and I couldn’t be happier. Bike has awesome power. I’ll never buy another brand-name piston again other than this one.

Namura piston kit
I have used these kits in several of my Polaris four wheelers and have always been pleased with the outcome. All the items included are of excellent quality and have not had any issues with anything. Just make sure your honing or boring is to spec as well as ring end gap. Awesome kit for an excellent price.
