At the heart of the 1998 KTM 620 LSE enduro - offroad motorcycle, KTM pairs a 609 cc (37.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 50 HP (36.5 kW) at 7,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 82.1 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the 620 LSE measures 140 kg (309 lbs) dry, translating to a power-to-weight ratio of 0.36 HP/kg (2.8 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.
