Introducing the 2024 KTM 125 Duke…

The 2024 KTM 125 DUKE is your entry point to the DUKE revolution. An ultra-capable machine in the city or out of it. THE SPAWN OF THE BEAST is the perfect first step into the no-nonsense world of KTM Naked bikes.

The KTM 125 DUKE might only boast 125 cc, but rest assured – this machine is 125% DUKE! Built with the same NAKED ethos as its bigger brethren, the 2024 KTM 125 DUKE boasts an all-new, muscled-up attitude, complete with a fresh new frame, suspension package, LED lights, riding tech, and street-ripping, turn-gripping aggression.

While it might sit at the entry level of the KTM Naked range, the KTM 125 DUKE dominates the small capacity engine segment. A powerful 125 cc engine, exceptional electronics, and WP APEX suspension lift the 2024 KTM 125 DUKE to new heights.

Visually, the 2024 KTM 125 DUKE sets itself apart from the rest of the small DUKE range, with all-new Electronic Orange and Atlantic Blue color options, painted headlight surround housing an ultra-bright LED headlight, and compact tank spoilers.

Electronically, the 2024 KTM 125 DUKE shares its 5” TFT display with the KTM 390 DUKE, with the option of TRACK screen being selected, and Cornering ABS as standard. A refined ride-by-wire system and Automatic Turn Indicator Reset complete the package.

The 2024 KTM 125 DUKE also features a 43 mm WP APEX Open Cartridge non-adjustable front fork with 150 mm travel and a WP APEX Separate piston shock absorber with tool-adjustable preload.

Enhancing the new 2024 generation KTM DUKE line-up even further, a comprehensive selection of KTM PowerParts and KTM PowerWear is specifically designed to fit the new DUKE range and its riders, providing performance, style, protection, and comfort.

2024 KTM DUKE models will be available in selected markets from September 2023 onwards.


KTM charges into model year 2024 with a brace of all-new single-cylinder DUKE models, bringing more punching power, improved handling, and clear differentiation of attitude between the displacements. In short, the all-new DUKE range cuts the bullshit, bringing more bike for your buck.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+.

Bringing more DUKENESS to each division – apart from a new metal fuel tank and high-quality surface finishes – the 2024 DUKE stablemates have embraced their own identities with visual differences across the range.

A true Naked bike is pure and exposed. No fairings or windscreens required. The 2024 KTM DUKE Range models, unlike the competition, are purpose-built Naked bikes rather than stripped down Superbikes.

As KTM celebrates the 30th anniversary of this iconic range of motorcycles, it aims to be as brutally authentic as possible. Naked from the ground up.




Finding that perfect balance when attacking your favorite stretch of tarmac, or sliding around some tight cone-marked corners is easy thanks to the KTM 125 DUKE’s WP APEX Separate piston shock absorber and also be set for preload, white hand levers can be adjusted for reach.


TFT Display & Connectivity

Everything you need at a glance. The 2024 KTM 125 DUKE features an all-new 5″ bonded glass TFT dashboard. This is paired with a new switch cube, with 4-way menu switches that allow easy interaction with all vehicle functions – even smartphone connectivity. Speaking of which, All new generation DUKE models are equipped with connectivity functions, allowing pilots to play music, take incoming calls, and get to where they are going with Turn-by-Turn navigation.



Embracing its NAKED lineage, the 2024 KTM 125 DUKE has no shame in bearing it all. Casting an ever-impressive shadow, bristling with shark-like edges and visible air intakes, and painted headlight surround, the 2024 KTM 125 DUKE boasts an aggressive stance. A new metal fuel tank, color-injected plastics, and LED lights complete the package.

100% DUKE

3, 2, 1 – LAUNCH!



Boasting the latest generation in LC4c engines, the 2024 KTM 125 DUKE muscles up with more power, smoother acceleration, and lighter overall weight than before. Drawing from years of experience in the small engine game, the 2024 KTM 125 DUKE now also features an improved gearbox, and an optimized cylinder head, and is ready to adopt EURO5.2 emission standards. Oh, and did we mention is also READY TO RACE?


LED Lighting

Tearing a deep gash into the night, all 2024 KTM DUKE models come equipped with powerful LED lights in the front and at the rear. Not only do these work when the world becomes dark, but they also provide improved visibility when navigating busy traffic or misty road conditions.





Thanks to a slightly longer wheelbase, new seat heights, and frame geometry, the 2024 DUKE range boasts dramatically improved cornering behavior, stability, and handling proficiency. This, along with an already sterling reputation as being THE SPAWN OF THE BEAST and an aggressive seating position, means the 2024 KTM 125 DUKE sets the standard when it comes to energetic NAKED machinery.



Improved comfort for the rider and pillion, thanks to thicker seat foam, a narrower profile, and an overall improvement in general ergonomics. Need for more or less seat height? The 2024 KTM 125 DUKE has a standard seat height of 800 mm, but can easy be increased to 820 mm with the optional KTM PowerParts seat offering.



All-new, lightweight forged aluminum footpeg hangers and grippy footpegs ensure riders have uninterrupted grip when banging through the gears, with high-end CNC-machined footpegs available from the KTM PowerParts catalog.





The new design features a 2-piece construction composed of an all-new steel trellis main frame with a pressure die-cast aluminum subframe. The rear shock absorber is now also mounted off-center to allow for a larger airbox while reducing seat height and, at the same time, adding to the DUKE’s aggressive stance. Not only designed for looks, the primary objective of the frame design is to enhance vehicle dynamics by augmenting torsional rigidity, improved agility, and enhanced feedback from the chassis.



A new curved cast aluminum swingarm provides a sturdy and durable platform for the rear suspension system, featuring a direct shock absorber mount that is now offset to the side, for that super-racy look. This also creates additional space for the new exhaust muffler, providing added attitude.



Upfront, a 43 mm WP APEX open cartridge fork with 150 mm travel keeps things in check, ensuring rock-solid performance on all street conditions.


Rear Shock

On the rear, you’ll find an off-center WP APEX Separate piston shock absorber with 150 mm of travel and 60 mm of stroke. The rear shock is also preload adjustable.


Wheels and Tires

Reducing weight where it counts the most, the 2024 KTM DUKE range has made significant inroads at reducing unsprung mass thanks to a set of lightweight wheels and grippy Michelin Road 5 tires. This not only improves the overall handling characteristics but also means quicker turn-in and less strain on working components like axels and bearings.



On the front wheel, the KTM 125 DUKE boasts a 320 mm brake disk with brand-new four-piston radial calipers. The new design includes bigger disks to reduce the operating temperature with improvements in the resistance to fading and longer pad lifespan. On the rear wheel, a 240 mm brake disk is installed with a brand-new twin-piston caliper which carries the same benefits as the front wheel. Cornering ABS and SUPERMOTO ABS are also standard features.
