2011 KTM 690 Duke R Technical Analysis & Specification Breakdown
Engineered by KTM for the naked motorcycle segment, the 2011 KTM 690 Duke R features a 690 cc (42.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 69.1 HP (50.4 kW) at 7,500 rpm while maximum torque reaches 70 Nm (51.6 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 100.1 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 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 690 Duke R measures 148 kg (326 lbs) dry, translating to a power-to-weight ratio of 0.47 HP/kg (2.14 kg per horsepower). Rider ergonomics and chassis geometry center around a 865 mm (34.1 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,472 mm (58 in) wheelbase engineered for balanced agility and highway composure. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
