Product Details
This Athena cast piston kit includes the piston itself, designed to fit your Yamaha YZ 125 from 1997 to 2021. It's a 53.94mm bore size piston, intended for 2-stroke engines.
Athena uses special alloys of nickel, silica, and aluminum to build these pistons. This construction aims to match the reliability you'd expect from an original equipment piston, while also offering increased durability and solid performance. The piston's smooth profile is meant to help with regular fuel flow and proper flame propagation inside the cylinder.
For some piston designs, Athena applies a molybdenum disulfide coating to the skirt using screen printing. This treatment is intended to further reduce friction, which can help improve both performance and how long the piston lasts.
