Turbo High Flow Cooling Fan for GY6 50cc (139QMB) & Scooters

Turbo High Flow Cooling Fan for GY6 50cc and 125/150cc Scooters

This Turbo High Flow Cooling Fan is made for air-cooled 139QMB 50cc and GY6 125/150cc scooter engines. 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 GY6 50cc scooter parts that can boost cooling without adding extra weight.

Cooling Efficiency

The 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.

Lightweight Construction

Weighing 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.
