Built around KTM's enduro - offroad motorcycle platform, the 1998 KTM 400 LSE utilizes a 398 cc (24.3 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 42 HP (30.7 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 105.5 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 400 LSE measures 138 kg (304 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.29 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
