2024 KTM 125 Duke Technical Analysis & Specification Breakdown

Engineered by KTM for the naked motorcycle segment, the 2024 KTM 125 Duke utilizes a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) while maximum torque reaches 11.5 Nm (8.5 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.5 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 125 Duke measures 139 kg (306 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.39 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,357 mm (53.4 in) wheelbase engineered for quick, flickable steering geometry. The 13.4-liter (3.5 US gal) fuel tank paired with a rated consumption of 2.42 L/100 km provides an estimated theoretical range of roughly 554 km (344 miles) between fill-ups.

Within MotoLibrary's KTM archive, this model family spans 15 indexed model years from 2011 to 2026, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
