This flap restricts airflow through the radiator core, allowing the mechanic to regulate coolant temperature during a session. By partially or fully covering the radiator face, the flap raises coolant temperature on cold or wet days — keeping the engine in its optimal thermal operating range. Running too cold is as harmful as overheating on a high-performance two-stroke engine.\u003c\/p\u003e\n\u003cp\u003eFits: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO\u003c\/strong\u003e.
