Enhancing the new 2026 generation KTM DUKE line-up even further, a comprehensive range of KTM PowerParts and KTM PowerWear is specifically designed to fit the new DUKE range and its riders, providing performance, style, protection, and comfort.

Drawing from years of experience in the small engine game, the KTM 125 DUKE also features an the same improved gearbox, and a optimized cylinder head as found on the 2024 model.
The KTM 125 DUKE gives its riders a selection of RIDE MODES to best suit their riding style and environment.

Both modes can be easily selected via the TFT display.
Tearing a deep gash into the night, all 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 long wheelbase, low seat height, and excellent frame geometry, the KTM DUKE range boasts class-leading 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 KTM 125 DUKE sets the standard when it comes to energetic NAKED machinery.
Improved comfort for the rider and pillion, thanks to thick seat foam, a narrow profile, and an overall excellent performance in ergonomics. Need for more or less seat height? The KTM 125 DUKE has a standard seat height of 31.4 in (800 mm), but can easy be increased to 32.2 in (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 design features a 2-piece construction composed of a steel trellis main frame with a pressure die-cast aluminum subframe. The rear shock absorber is mounted off-center to allow for the large airbox which allows for the lower 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, nimble agility, and enhanced feedback from the chassis.
A curved cast aluminum swingarm provides a sturdy and durable platform for the rear suspension system, featuring a direct shock absorber mount that is 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.
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.
Reducing weight where it counts the most, the KTM 125 DUKE 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 a four-piston radial calipers. The 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 single-piston caliper which carries the same benefits as the front wheel. Cornering ABS and SUPERMOTO ABS are also standard features.
