Engineered by KTM for the enduro - offroad motorcycle segment, the 2001 KTM EXC 400 features a 398 cc (24.3 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 44 HP (32.1 kW) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 110.6 HP per liter, 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 EXC 400 measures 122 kg (269 lbs) wet (curb), translating to a power-to-weight ratio of 0.36 HP/kg (2.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 930 mm (36.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
