Positioned in Yamaha's scooter motorcycle lineup, the 2018 Yamaha Vega relies on a 114 cc (7 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.1 HP (5.9 kW) at 7,500 rpm while maximum torque reaches 8.3 Nm (6.1 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 71.1 HP per liter and a 3,000 rpm working window between peak torque (4,500 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 Vega measures 99 kg (218 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,235 mm (48.6 in) wheelbase engineered for quick, flickable steering geometry. The 4.2-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
