About this part

Product Details

If you're rebuilding the top end of your Fantic XEF 250, a strong forged piston is key. This Athena piston is built for that job, offering a reliable replacement that also handles more stress than a stock cast piston. It's made from a special aluminum alloy with nickel and silica, which Athena uses to match the reliability of original equipment while giving you more durability and better performance.

Athena uses advanced CNC machining to hold very tight tolerances, less than 0.01 mm, ensuring a precise fit inside your cylinder. The piston's surface is smooth, which helps with regular fuel flow and proper combustion. This means you get consistent power delivery and the piston can handle the heat and pressure of off-road riding.
