At the heart of the 2012 Yamaha Aerox WGP 50th Anniversary scooter motorcycle, Yamaha pairs a 49.2 cc (3 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 2.7 HP (2 kW) at 6,500 rpm while maximum torque reaches 3.7 Nm (2.7 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 7.4:1 compression ratio.
On the scales, the Aerox WGP 50th Anniversary measures 97 kg (214 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 828 mm (32.6 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,256 mm (49.4 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
