Built around Suzuki's naked motorcycle platform, the 2011 Suzuki B-King utilizes a 1340 cc (81.8 cu in) oil & air-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 181 HP (132.1 kW) at 9,500 rpm while maximum torque reaches 146 Nm (107.7 lb-ft) at 7,200 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 135.1 HP per liter and a 2,300 rpm working window between peak torque (7,200 rpm) and peak power (9,500 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 B-King measures 235 kg (518 lbs) dry, translating to a power-to-weight ratio of 0.77 HP/kg (1.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,525 mm (60 in) wheelbase engineered for planted straight-line stability. The 16.5-liter (4.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
