PISTON KIT 100MM KAWASAKI KX/KLX 450 05-17, ATHENA S4F10000011A FOR 490CC BIG BORE
Athena forged racing piston with a 99.95 mm bore diameter. Designed for Athena Big Bore cylinder kits, this piston is manufactured using advanced CNC machining tools to ensure dimensional tolerances of less than 0.01 mm. It is constructed from a special high-performance aluminum alloy with a high silicon content, providing reliability and enhanced resistance and performance. Some piston skirts feature a molybdenum disulfide coating to reduce friction. The piston rings, produced in Japan with wear-resistant coatings, ensure less friction and higher performance. This kit includes the piston, pin, circlips, and piston rings. Technical features include a Big End Pin Diameter of 19x10x51 mm, a Compression Height of 29.00 mm, a standard Compression Ratio, a Displacement of 450 cc, a Net Weight of 0.41 Kg, 2 segments, and a biconical piston pin type. This product is intended exclusively for competitive use where its increased displacement and power exceed road code regulations.

FULL DESCRIPTION
Athena Forged Racing Piston Kit for Big Bore Cylinders
Elevate your motorcycle's performance with this Athena forged racing piston kit, specifically engineered for Athena Big Bore cylinder applications. Crafted by Athena, a leader in motorcycle spare parts with over 40 years of experience, this piston is designed for enthusiasts seeking enhanced power and reliability.
The piston is manufactured using advanced CNC machining tools, ensuring precise dimensional tolerances of less than 0.01 mm. It is constructed from a special high-performance aluminum alloy with a high silicon content, offering a combination of OE-level reliability and superior resistance and performance. The piston's perfectly smooth profile promotes regular airflow and optimal flame propagation.
To further reduce friction and boost performance and durability, some piston skirts feature a molybdenum disulfide coating applied through screen printing. Each piston is meticulously engineered in Italy by the Athena R&D department, undergoing rigorous testing on engine dynamometer benches and on the track to validate its performance under extreme conditions.
This piston kit includes piston rings, a piston pin, and circlips. The piston rings, produced in Japan with wear-resistant coatings, are designed for reduced friction against the cylinder, leading to higher performance and increased durability. They ensure a perfect fit to the cylinder liner even under low tangential load.
