Manufacturer: Athena
Dennis Kirk Part #: 130029SB
Athena Forged Piston Kit - 53.95mm Bore: Manufacturer part # S4F05400009B - 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. HOW TO ORDER PISTONS S is Standard. SB is +.0004 in. (.01 mm). SC is +.0008 in. (.02mm). 1 is +.010 in. (.25mm). 2 is +.020 in. (.50mm). 3 is +.030 in. (.75mm). 4 is +.040 in. (1.0mm). 5 is +.050 in. (1.25mm). 6 is +.060 in. (1.50mm). 8 is +.080 in. (2mm). , , This is a fractional oversize piston of .0004 in. (four-ten-thousandths inch). It is intended for slightly worn cylinders.
