TOP END PISTON & GASKET KIT 79MM HONDA CRF 250 20-21, ATHENA P5F0790319002B, SET B

Athena Top End Piston and Gasket Kit

This Athena Top End Piston Kit offers a perfectly matched set of a forged 4-stroke piston and a top-end gasket kit. Engineered for high performance and maximum reliability, this kit combines essential engine components for optimal results.

Athena meticulously studies, develops, and tests all piston technologies and materials in-house, ensuring the development of compatible, high-quality gaskets. This integrated approach results in a tuned kit that delivers exceptional performance and ensures maximum reliability after a piston replacement.

Key Features:

• Forged 4-Stroke Piston: Manufactured using state-of-the-art numerical control (CNC) machines from a special high-performance aluminum alloy with a high silicon content. This provides OE-level reliability with enhanced resistance and excellent performance.
• Smooth Profile: The piston's perfectly smooth profile promotes a regular flow and perfect flame propagation. Some pistons feature a molybdenum disulfide coating on the skirts, applied by screen printing, to further reduce friction.
• High-Performance Piston Rings: Included piston rings, manufactured in Japan, feature wear-resistant coatings (PVD or chromium nitride) to reduce friction with the cylinder, increasing performance and durability.
• Reliable Gasket Kit: Athena gaskets are developed with over 40 years of industry experience, constant technological advancement, and strict adherence to manufacturer parameters. Latest generation lasers ensure perfect cutting quality.
• Advanced Gasket Materials and Treatments: Athena utilizes a wide availability of raw materials, performs surface treatments to compensate for irregularities, and employs material stress-relieving processes for improved sealing in critical areas.
