FULL DESCRIPTION
Athena Forged Piston Kit B 82mm for Honda CRF 250cc (2010-2017) - 284cc Big Bore
This high-performance forged piston kit from Athena is engineered to enhance the power and reliability of your Honda CRF 250cc. Designed for big bore applications, this kit provides a 284cc displacement with a 13.5:1 compression ratio, offering a significant upgrade for off-road enthusiasts.
Athena pistons are manufactured using advanced reverse extrusion and cutting-edge CNC machining tools, ensuring dimensional tolerances of less than 0.01 mm. Constructed from a special high-performance aluminum alloy with a high silicon content, these pistons offer superior resistance and excellent performance while maintaining the reliability of original equipment.
Some piston skirts feature a molybdenum disulfide coating applied by screen printing, which further reduces friction, enhancing both performance and durability. Each piston is rigorously tested on engine dynamometer benches and on track in extreme conditions to validate its performance and reliability.
This comprehensive kit includes the forged piston, piston pin, circlips, and piston rings. The piston rings, produced in Japan with wear-resistant coatings like PVD or chromium nitride, are designed for reduced friction and increased durability, adapting perfectly to the cylinder liner even at low tangential loads.
