Built around Suzuki's sport motorcycle platform, the 2008 Suzuki GSR 400 ABS relies on a 398 cc (24.3 cu in) liquid-cooled four cylinder boxer, four-stroke powerplant. In factory specification, peak output is rated at 52.3 HP (38.2 kW) at 11,000 rpm while maximum torque reaches 37 Nm (27.3 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 131.4 HP per liter and a 2,000 rpm working window between peak torque (9,000 rpm) and peak power (11,000 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 GSR 400 ABS measures 190 kg (419 lbs) dry, translating to a power-to-weight ratio of 0.28 HP/kg (3.63 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
