2021 Ktm 890 Duke R Technical Analysis & Specification Breakdown
Built around Ktm's naked motorcycle platform, the 2021 Ktm 890 Duke R relies on a 889 cc (54.3 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 119.4 HP (87.1 kW) at 9,000 rpm while maximum torque reaches 99 Nm (73 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 134.3 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 890 Duke R measures 166 kg (366 lbs) dry, translating to a power-to-weight ratio of 0.72 HP/kg (1.39 kg per horsepower). Rider ergonomics and chassis geometry center around a 834 mm (32.8 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-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.74 L/100 km provides an estimated theoretical range of roughly 295 km (183 miles) between fill-ups.
