2024 KTM 990 Duke Technical Analysis & Specification Breakdown
At the heart of the 2024 KTM 990 Duke naked motorcycle, KTM features a 947 cc (57.8 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 121.4 HP (88.6 kW) at 9,000 rpm while maximum torque reaches 103 Nm (76 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 128.2 HP per liter and a 1,000 rpm working window between peak torque (8,000 rpm) and peak power (9,000 rpm), 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 990 Duke measures 179 kg (395 lbs) dry, translating to a power-to-weight ratio of 0.68 HP/kg (1.47 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 1,476 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 14.8-liter (3.9 US gal) fuel tank paired with a rated consumption of 4.7 L/100 km provides an estimated theoretical range of roughly 315 km (196 miles) between fill-ups.
