Built around Yamaha's scooter motorcycle platform, the 2019 Yamaha Aerox 155VVA utilizes a 155 cc (9.5 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 8,000 rpm while maximum torque reaches 18.7 Nm (13.8 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 95.5 HP per liter and a 1,750 rpm working window between peak torque (6,250 rpm) and peak power (8,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Aerox 155VVA measures 116 kg (256 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.84 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 4.6-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
