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
