KTM charges into model year 2024 with a brace of all-new single-cylinder DUKE models, bringing more power, improved handling, and clear differentiation between the displacements.
Adopting an all-out, no-compromise attitude, the all-new 2024 models represent the biggest change to the sub-500 cc capacity DUKE model range since the KTM 125 DUKE in 2011. The result is a complete redesign, with new engines, an all-new chassis concept, and new styling which amplifies the typically aggressive KTM DUKE design language you’ve come to expect.
For 2024, a new 2-piece frame design – composed of an all-new steel trellis main frame with a pressure die-cast aluminum subframe – enhances dynamics by augmenting torsional rigidity. This also adds improved agility and enhanced feedback from the chassis, with new triple clamps and a revised offset, improving handling characteristics and giving riders greater control and stability.
The frame is now also mated to an all-new curved lightweight swingarm, which contours around a relocated rear shock absorber. This is mounted off-center to allow for a larger airbox design while reducing overall seat height. Speaking of which, the reduced seat height was purposefully engineered into the new DUKE design to allow for greater accessibility, without compromising on stability or handling.
Delivering the knockout punch is an entirely new generation of lightweight, compact single-cylinder engines. Dubbed the LC4c, the engine range is made up of a smaller 125 cc and a 250 cc (for selected markets) engine and a larger 399 cc engine, as found in the KTM 390 DUKE. Building from the experience gained with the previous generation, these powerplants are completely redesigned, with newly optimized cylinder heads, and gearboxes, as well as meeting EURO 5.2 compatibility standards.
The 2024 KTM DUKE range also sets the benchmark for real-world technological advancement in the small displacement NAKED segment. All models in the line-up feature the latest version of selectable Supermoto ABS, 5” dashboards, and smartphone connectivity as standard – with the ability to fit an optional Quickshifter+.
The 2024 KTM 250 DUKE gets a smaller tank spoilers compared to the KTM 390 DUKE. These are aligned with painted headlight surrounds and a lower seat height. A new 5” LCD display, LED headlight, and all-new Electronic Orange and Ceramic White color options, set it apart from the rest of the range.
The 2024 KTM 250 DUKE features an improved power-to-weight ratio over the previous generation, with a new Single overhead cam (SOHC) design that is lighter and simpler with fewer components, ride-by-wire, and a power assist slipper clutch. Only removing the camshaft, and retaining everything seems like a great move by KTM!
Suspension is taken care of by a non-adjustable 43 mm WP APEX Open Cartridge big piston fork setup with 150 mm of travel, and a WP APEX Emulsion shock absorber, with preload adjustability on the rear.
