2006 Honda CB 400 Super Four Technical Analysis & Specification Breakdown
Positioned in Honda's naked motorcycle lineup, the 2006 Honda CB 400 Super Four utilizes a 399 cc (24.4 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 52.3 HP (38.2 kW) at 11,000 rpm while maximum torque reaches 38 Nm (28 lb-ft) at 9,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 131.1 HP per liter and a 1,500 rpm working window between peak torque (9,500 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 CB 400 Super Four measures 198 kg (437 lbs) wet (curb), translating to a power-to-weight ratio of 0.26 HP/kg (3.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 5.59 L/100 km provides an estimated theoretical range of roughly 322 km (200 miles) between fill-ups.
