Athena S410485001180 Head Gasket Kit Yamaha YZ450F 98.2mm Bore 0.75mm Thick

The Athena S410485001180 is a precision-engineered cylinder head gasket kit designed specifically for 2003-2004 Yamaha YZ450F models with a 98.2mm bore diameter and 0.75mm gasket thickness. This critical sealing component ensures proper compression and prevents leakage between the cylinder head and engine block.

Advanced Manufacturing Technology:

• High-Precision Laser Cutting: Latest generation laser technology delivers exceptional cutting accuracy and purity, completely eliminating production burrs that can cause oil, coolant, or compression gas infiltration
• Optimized Relief Alignment: Precisely aligned relief patterns increase gasket elasticity during operation, maintaining excellent sealing pressure over time even under extreme conditions
• Advanced Materials: Constructed using metal/elastomer combinations or multilayer steel with specialized coating materials for superior durability and heat resistance
• Elastic Memory Design: Engineered to maintain compression sealing throughout the gasket's service life, preventing flattening and loss of sealing capability

Quality Assurance:

• Rigorously tested during both design phase and bench testing to meet demanding performance standards
• Meticulous quality control ensures reliable engine operation and longevity
• OEM-specification bore diameter and thickness for precise fitment

Athena head gaskets represent the first critical step toward building a reliable, high-performance engine. Each gasket is manufactured to exacting tolerances to ensure proper sealing of combustion chambers, oil passages, and coolant channels.
