Engineered by Bajaj for the naked motorcycle segment, the 2021 Bajaj Dominar 400 relies on a 373.3 cc (22.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 39.4 HP (28.8 kW) at 8,800 rpm while maximum torque reaches 35 Nm (25.8 lb-ft) at 6,500 rpm. With a specific output of 105.5 HP per liter and a 2,300 rpm working window between peak torque (6,500 rpm) and peak power (8,800 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 Dominar 400 measures 187 kg (412 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,453 mm (57.2 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
