PISTON KIT B 95mm KTM SX-F450 21-22, HUSQVARNA, ATHENA S5F09500002B
This Athena forged piston kit features a 94.96mm bore and is engineered for OE cylinders. Manufactured using reverse extrusion and precision CNC machining, the piston ensures dimensional tolerances below 0.01mm. Constructed from a high-silicon aluminium alloy, it offers durability and performance on par with or exceeding OE standards. The kit includes the piston, pin, circlips, and rings, with low-friction coatings to maximise reliability and efficiency. Features include a forged piston made using reverse extrusion and CNC machining, constructed from high-performance aluminum alloy with high silicon content, tolerances below 0.01mm for OE-level fit and function, a flat head design for consistent combustion, piston rings with PVD or chromium nitride coatings for enhanced wear resistance, and a molybdenum disulfide skirt coating for reduced friction. Developed, engineered, and bench-tested in Italy. Specifications: Bore Size: 94.96mm, Displacement: 449 cm³, Compression Ratio: 12.8:1, Compression Height: 22.80 mm, Number of Segments: 2, Piston Head Type: Flat, Piston Type: Forged, Piston Pin Type: Biconical, Pin Dimensions: 19 x 10 x 45 mm. Cross-Reference OEM Part Numbers: S5F09500002B.
