It is meant to help keep the engine cool when running at idle as well as during hard riding. The blade shape moves noticeably more air than a standard fan, which helps the engine manage its temperature. It is one of the \u003ca href=\"\/collections\/gy6-50cc-parts\"\u003eGY6 50cc scooter parts\u003c\/a\u003e that can boost cooling without adding extra weight.\u003c\/p\u003e\u003ch3\u003eCooling Efficiency\u003c\/h3\u003e\u003cp\u003eThe fan uses a turbo swept-blade layout that pulls in more air than a stock fan does. Its curved blades push extra air across the engine, which supports cooling. That added airflow helps keep cylinder head temperatures in check during long idling stretches or demanding rides.\u003c\/p\u003e\u003ch3\u003eLightweight Construction\u003c\/h3\u003e\u003cp\u003eWeighing only 56 grams, the fan adds very little rotating mass to the scooter's flywheel. Less mass means the engine can respond more quickly to throttle input and perform better overall. Brass sleeves line the mounting holes, giving a firm connection that stays stable while the engine runs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 118mm (4.65 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 30mm (1.17 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 10 brass-sleeved bolt holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Race-red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e 139QMB\/139QMA 50cc GY6 engines and GY6 125\/150cc engines (152QMI, 157QMJ, 161QMK families)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e139QMB \/ 139QMA 50cc GY6 engines (139QMA, 139QMB, 1P39QMB, 1P39QMA-2, YN139QMB, JJ1P39QMB, BD1P39QMB, BN139QMB)\u003c\/li\u003e\n\u003cli\u003eGY6 125\/150cc engines (152QMI, 157QMJ, 1P57QMJ, YN1P57QMJ, JJ157QMJ, BN157QMJ)\u003c\/li\u003e\n\u003cli\u003eGY6 161QMK engines (161QMK, 1P61QMK, BN161QMK-A)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Find the engine code stamped on your crankcase and compare it with the list above.
