At the heart of the 2001 KTM LC4 620 Supermoto super motard motorcycle, KTM utilizes a 609 cc (37.2 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 50 HP (36.5 kW) at 7,500 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 LC4 620 Supermoto measures 123 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.41 HP/kg (2.46 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, combined with a 1,510 mm (59.4 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 175 km/h (109 mph).
