About this part

Product Details

Forged from a special aluminum alloy containing nickel and silica, this Athena piston is built for demanding off-road use on your 2021-2024 Kawasaki KX 250 4T. The forging process itself creates a stronger, more durable piston than a cast alternative, and Athena uses advanced CNC machining to hold tolerances to less than 0.01 mm. This attention to detail ensures a precise fit and contributes to smooth operation and consistent flame propagation within the cylinder.

Athena has been making motorcycle parts for over 40 years, and their goal with this piston was to match the reliability of the original equipment while offering increased resistance and better performance. The perfectly smooth piston profile helps ensure a regular flow of the air-fuel mixture and proper combustion, which can make a difference in how your bike runs.
