Manufacturer: Athena
Dennis Kirk Part #: 1300684
Athena Forged Piston Kit - 95.94mm Bore: Manufacturer part # S4F096000001 - High quality 2- and 4-stroke pistons. 2-stroke pistons are 4032 silicium construction. 4-stroke pistons are 2618 silicium construction ? same material used to produce Formula 1 pistons. Both include 3 percent copper for better heart resistance. Precision heat-treatment forging process allows for production tolerances of just .005mm. All tooling allows for the lightest available product. Includes anti-wear coated piston, rings, pin and circlip. 2-stroke rings fit OEM pistons also. Made in Germany. Sold as each.
