At the heart of the 2021 Suzuki Burgman 400 scooter motorcycle, Suzuki pairs a 400 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 29 HP (21.2 kW) at 6,300 rpm while maximum torque reaches 35.2 Nm (26 lb-ft) at 4,900 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 72.5 HP per liter and a 1,400 rpm working window between peak torque (4,900 rpm) and peak power (6,300 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 Burgman 400 measures 218 kg (481 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.52 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 1,580 mm (62.2 in) wheelbase engineered for planted straight-line stability. The 13.5-liter (3.6 US gal) fuel tank paired with a rated consumption of 3.33 L/100 km provides an estimated theoretical range of roughly 405 km (252 miles) between fill-ups.
