About this part

Product Details

If you're rebuilding the top end of your 2004-2009 Honda CRF 250 R, a strong forged piston is key to getting your engine running right. This Athena piston is made from a special aluminum alloy with nickel and silica, designed to handle the demands of off-road riding while maintaining the reliability you expect from an OE part.

Athena uses advanced CNC machining to hold incredibly tight tolerances, less than 0.01 mm, ensuring a precise fit inside your cylinder. The reverse extrusion process and the smooth piston profile help with regular fuel flow and proper flame propagation, which can lead to improved performance and a more consistent burn. This well-built piston offers greater resistance compared to stock, giving you confidence on the trail or track.
