Positioned in Yamaha's naked motorcycle lineup, the 2021 Yamaha Vixion features a 149.8 cc (9.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 16.4 HP (11.9 kW) at 8,500 rpm while maximum torque reaches 14.5 Nm (10.7 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 109.5 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 Vixion measures 132 kg (291 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.05 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
