Built around KTM's super motard motorcycle platform, the 2011 KTM 990 Adventure relies on a 999 cc (61 cu in) liquid-cooled v2, two-stroke powerplant. In factory specification, peak output is rated at 104.6 HP (76.4 kW) at 8,250 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 104.7 HP per liter and a 1,500 rpm working window between peak torque (6,750 rpm) and peak power (8,250 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 Adventure measures 209 kg (461 lbs) dry, translating to a power-to-weight ratio of 0.5 HP/kg (2 kg per horsepower). Rider ergonomics and chassis geometry center around a 860 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,570 mm (61.8 in) wheelbase engineered for planted straight-line stability. The 19.5-liter (5.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
