At the heart of the 2022 Yamaha NM-X scooter motorcycle, Yamaha relies on a 155 cc (9.5 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14.9 HP (10.9 kW) at 8,000 rpm while maximum torque reaches 14.4 Nm (10.6 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 96.1 HP per liter and a 2,000 rpm working window between peak torque (6,000 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 NM-X measures 127 kg (280 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.52 kg per horsepower). Rider ergonomics and chassis geometry center around a 765 mm (30.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 6.6-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
