2001 Suzuki DR-Z 400 S Technical Analysis & Specification Breakdown

At the heart of the 2001 Suzuki DR-Z 400 S enduro - offroad motorcycle, Suzuki pairs a 398 cc (24.3 cu in) single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 40 HP (29.2 kW) at 7,600 rpm while maximum torque reaches 39 Nm (28.8 lb-ft) at 6,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 100.5 HP per liter and a 1,000 rpm working window between peak torque (6,600 rpm) and peak power (7,600 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 DR-Z 400 S measures 132 kg (291 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 935 mm (36.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 140 km/h (87 mph).
