This 18mm diameter header socket is specifically sized for the Micro MAX class and replaces the standard 37mm diameter socket used on Senior and Junior MAX engines. The reduced bore diameter is a class-specific restriction that limits exhaust flow and engine power output to the Micro MAX specification — it is a sealed, scrutineered component and must be present and unmodified for technical compliance.\u003c\/p\u003e\n\u003cp\u003eFits: \u003cstrong\u003eRotax 125 Micro MAX EVO\u003c\/strong\u003e only.
