Technical Overview
2020 Ktm 790 Duke L Technical Analysis & Specification Breakdown
Positioned in Ktm's naked motorcycle lineup, the 2020 Ktm 790 Duke L relies on a 799 cc (48.8 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 93.9 HP (68.5 kW) while maximum torque reaches 86 Nm (63.4 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 117.5 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 790 Duke L measures 169 kg (373 lbs) dry, translating to a power-to-weight ratio of 0.56 HP/kg (1.8 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,475 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
