About this part

Product Details

This Athena 4T forged racing piston kit includes the piston itself, designed for the 2003-2007 Kawasaki KLX 400. It features an 89.94mm bore size, intended to replace the original equipment piston while offering improved durability and performance.

Athena uses a reverse extrusion process to create these pistons from special high-performance alloys, including nickel, silica, and aluminum. This construction aims to match the reliability of original parts while providing greater resistance to stress and heat. The precise CNC machining, with tolerances under 0.01 mm, ensures a perfect fit and smooth operation, contributing to regular fuel flow and efficient flame propagation within the cylinder.
