Built around KTM's enduro - offroad motorcycle platform, the 1998 KTM 400 EGS relies on a 398 cc (24.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 50 HP (36.5 kW) at 7,300 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 125.6 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 400 EGS measures 137 kg (302 lbs) dry, translating to a power-to-weight ratio of 0.36 HP/kg (2.74 kg per horsepower). Rider ergonomics and chassis geometry center around a 940 mm (37 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control.
