Built around Suzuki's custom - cruiser motorcycle platform, the 2012 Suzuki Intruder Classic 400 relies on a 399 cc (24.4 cu in) oil & air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 33 HP (24.1 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 82.7 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.
On the scales, the Intruder Classic 400 measures 275 kg (606 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.33 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,655 mm (65.2 in) wheelbase engineered for planted straight-line stability. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 3.03 L/100 km provides an estimated theoretical range of roughly 495 km (308 miles) between fill-ups.
