2011 KTM 990 Super Duke Technical Analysis & Specification Breakdown
Engineered by KTM for the naked motorcycle segment, the 2011 KTM 990 Super Duke relies on a 999 cc (61 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 118 HP (86.1 kW) at 9,000 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.1 HP per liter and a 2,000 rpm working window between peak torque (7,000 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 Super Duke measures 186 kg (410 lbs) dry, translating to a power-to-weight ratio of 0.63 HP/kg (1.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 18.5-liter (4.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
