At the heart of the 2011 Suzuki Boulevard 400 custom - cruiser motorcycle, Suzuki features a 399 cc (24.4 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 32.2 HP (23.5 kW) at 8,000 rpm while maximum torque reaches 33 Nm (24.3 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 80.7 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
