Positioned in Yamaha's scooter motorcycle lineup, the 2017 Yamaha Vity pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.6 HP (6.3 kW) at 7,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 68.8 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Vity measures 110 kg (243 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
