2013 KTM 690 Duke Technical Analysis & Specification Breakdown
Positioned in KTM's naked motorcycle lineup, the 2013 KTM 690 Duke utilizes a 690 cc (42.1 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 67.1 HP (48.9 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 97.2 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 690 Duke measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.45 HP/kg (2.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,466 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 13.8-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
