Athena S410210001224 Big Bore Head Gasket Kit for Honda CRF450R 100.5mm

The Athena S410210001224 is a precision-engineered head gasket kit designed specifically for big bore applications on 2002-2004 Honda CRF450R motorcycles with a 100.5mm bore diameter. This gasket represents critical engine sealing technology that ensures reliable compression, oil containment, and coolant management in high-performance four-stroke engines.

Advanced Manufacturing Technology:

• High-Precision Laser Cutting: Manufactured using state-of-the-art laser technology to achieve exceptional dimensional accuracy and completely burr-free edges, preventing potential infiltration pathways for oil, coolant, or compression gases
• Optimized Relief Alignment: Engineered with precisely aligned relief structures that enhance gasket elasticity during thermal cycling and maintain consistent clamping force over extended service life
• Advanced Material Construction: Utilizes either metal/elastomer composite materials or multi-layer steel construction with specialized coating technology, depending on application requirements
• Elastic Memory Properties: Designed to maintain sealing integrity even under extreme operating conditions, preventing the flattening and compression loss associated with inferior gaskets

Application: This gasket kit is specifically sized for big bore cylinder conversions on Honda CRF450R models from 2002-2004 with a 100.5mm bore diameter. Each gasket undergoes rigorous quality control testing during both the design phase and bench testing to ensure optimal sealing performance and engine reliability.

Choosing a premium Athena head gasket is essential for maintaining proper engine compression, preventing fluid leaks, and ensuring long-term durability in demanding motocross and off-road riding conditions.
