At the heart of the 2015 Suzuki GSR 400 ABS naked motorcycle, Suzuki features a 398 cc (24.3 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 61 HP (44.5 kW) at 12,000 rpm while maximum torque reaches 39 Nm (28.8 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 153.3 HP per liter and a 2,000 rpm working window between peak torque (10,000 rpm) and peak power (12,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the GSR 400 ABS measures 215 kg (474 lbs) wet (curb), translating to a power-to-weight ratio of 0.28 HP/kg (3.52 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 3.13 L/100 km provides an estimated theoretical range of roughly 511 km (318 miles) between fill-ups.
