This genuine OEM Honda cylinder head is designed for liquid-cooled, single-cylinder 125cc two-stroke engines. It features a precision-machined hemispherical combustion chamber, central threaded spark plug port, and integrated coolant jacket with transfer passages to help regulate operating temperatures.
