Markets

Europe

In 1997 Yamaha introduced the Aerox to the European market. It came in two models, the 2-Stroke 50 cc (Internally known as the YQ50) powered by the Minarelli MA-50 horizontal Liquid cooled engine with a front and rear disc brake (DD), this engine came restricted to 45 km/h from the factory to follow European law on 50 cc mopeds. The 2-Stroke 101 cc (internally known as the YQ100) version powered by a horizontal 101 cc forced air cooled Minarelli 2-Stroke engine with a single front disc and a rear drum brake (SD). Both models came equipped with an automatic lubrication system with a separate oil tank for 2-Stroke oil.

Slight changes were made in 2003. The Aerox was renamed to Aerox R and the 101 cc model was discontinued. The 2-Stroke 50 cc model was updated with a newer exhaust, tachometer and a newer type of ignition and CDI. In 2013, Yamaha launched the updated Aerox with an updated body design and the introduction of the Aerox Naked and Aerox 4 (equipped with 4-stroke engine).
