ATHENA Engine Valve Intake
Description
Athena’s intake valves for motocross and enduro motorcycles are engineered to deliver long-lasting performance and durability under extreme conditions. Manufactured to match OEM specifications and tolerances, they are the ideal replacement for riders seeking high-quality components with hassle-free installation.
Fully compatible with original valve train components
Athena valves are direct replacements for OEM parts and can be installed without modifying valve springs, seals, retainers, or cotters. This ensures easy installation and preserves the original valve train dynamics.
OEM-grade materials for consistent performance
Each valve is made from the same material specified by the original manufacturer—either steel or titanium—to maintain correct weight, balance, and spring load. This guarantees proper function and long service life, even under high RPM and thermal stress.
Offroad-proven reliability
Backed by Athena’s racing experience and partnerships with factory teams in MXGP, AMA Supercross, and EnduroGP, these valves are built to withstand the harshest offroad environments while delivering consistent performance and reliability.
