Many scooters produced in China feature a copy of Honda's GY6 engine.
These engines are produced in several variations, 50cc versions are known as a 139QMA/QMB engine, 125cc versions are known as a 152QMI engine and 150cc versions are known as the 157QMJ engine. All GY6 copy engines are air-cooled 4-stroke with a chain-driven overhead camshaft and use a carburettor fuel delivery system. The GY6 engine has been copied by many Asian manufacturers and while all remain very much the same some may have slight differences.
