    The Yamaha Aerox is a lineup of single-cylinder scooters made by Yamaha since 1997, available in either 50 cc or 100 cc for the European market, and 125 cc or 155 cc for the Southeast Asian and Indian market with several different body designs.

    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).

    Southeast Asia

    Aerox 125 (2-valve)

    Aerox 125 LC

    The liquid-cooled 4-stroke 2-valve 125 cc model of the Aerox was launched in Indonesia in January 2016 under the name Aerox 125 LC. It had a claimed power output of 8.4 kW (11.3 hp; 11.4 PS) @ 9,000 rpm and 10.4 N⋅m (7.7 lb⋅ft) of torque at 6,500 rpm. It was only sold in Indonesia and discontinued ten months later due to low sales. This model was succeeded by the 155 cc Aerox 155.

    Aerox 125 (4-valve)/155

    The liquid-cooled 4-stroke 4-valve 125 cc/155 cc version of the Aerox (internally known as the GDR125/GDR155/GPR155) was unveiled at Sepang International Circuit in Malaysia in October 2016. It is powered by a 125 cc (unrelated to the engine used in Indonesian-only Aerox 125 LC) or bored-up 155 cc Blue Core engine equipped with Variable Valve Actuation (VVA) that produces a claimed power output of 8.8 kW (11.8 hp; 12.0 PS) or 11–11.3 kW (14.8–15.2 hp; 15.0–15.4 PS).
