Positioned in Honda's naked motorcycle lineup, the 2002 Honda CL 400 utilizes a 397 cc (24.2 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 29 HP (21.2 kW) at 7,000 rpm while maximum torque reaches 34 Nm (25.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 73 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 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 CL 400 measures 140 kg (309 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 162 km/h (101 mph).
