At the heart of the 2002 Suzuki GSX 1400 naked motorcycle, Suzuki utilizes a 1401 cc (85.5 cu in) in-line four, four-stroke layout. In factory specification, peak output is rated at 100 HP (73 kW) at 6,500 rpm while maximum torque reaches 126 Nm (92.9 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 71.4 HP per liter and a 1,500 rpm working window between peak torque (5,000 rpm) and peak power (6,500 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 GSX 1400 measures 228 kg (503 lbs) dry, translating to a power-to-weight ratio of 0.44 HP/kg (2.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,520 mm (59.8 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
