KTM 125 DUKE 2019



The KTM 125 DUKE may be the entry-level bike of the range, but it isn’t here to play games. It’s built with the same attitude as the bigger bikes – and it shows. It’s no holds barred with this urban warrior. This 4-stroke single cylinder has fuel-injection and a 6-speed transmission to deliver class-leading performance with low fuel consumption to keep you riding longer.

Motor og Eksos

A state-of-the-art, liquid-cooled, single-cylinder 125 cc engine drives The Spawn of the Beast. Twin overhead camshafts, four valves and electronic fuel-injection contribute to its class-leading performance and thanks to the balancer shaft, the power is delivered with the highest levels of smoothness.


The intricate engine design, state-of-the-art injection electronics and the close-ratio, 6-speed transmission not only help the KTM 125 DUKE to achieve impressive performance, but also extremely low fuel consumption. At the same time, thanks to the regulated catalytic converter, it produces only minimal emissions.


In order to meet the latest Euro 4 emission restrictions and sound regulations, the 125 DUKE is equipped with a side exhaust, including link pipe and silencer.


The latest materials and production technologies not only deliver the bike’s bountiful torque and punchy acceleration, but also good manners in everyday use and outstanding fuel economy. A bike as compact and nimble as this one, deserves to pack a solid punch. With 11 kW (15 hp) it is right at the limit of the […]


Exactly like they do in the 1290 SUPER DUKE R, the four valves in the cylinder head of the 125 DUKE are actuated by two overhead camshafts and ultra hard, carbon coated cam followers, providing reliability and longevity despite the engine’s high power output.



The KTM 125 DUKE’s chassis has a characteristic, lightweight steel trellis frame, turning this bike into a street surfer through the bends. Masses grouped close to the center of gravity maximize maneuverability and precision – preparing the 125 DUKE to win the rush hour slalom, day in, day out.


Equally lightweight and delicate as they are stable, the 17 inch cast light alloy wheels are fitted with tires from the world’s best suppliers. They are 110 mm wide at the front and an impressive 150 mm at the rear. The tires are selected on the basis of their high grip levels in both wet and dry […]


The KTM 125 DUKE’s high-quality upside-down fork from WP Suspension uses the latest open-cartridge technology, which offers impressive advantages because of its easy maintenance, simplicity and small amount of components. Therefore, it’s lightweight, rugged and has a broad spectrum of use for all demands, from relaxed cruising to hammering around on closed circuits.


Thanks to its progressive spring, you get maximum feedback wherever you take this jack-of-all-trades. The preload is adjustable, so you can count on well-balanced suspension whether you’re riding solo or two-up, with or without luggage.


The 13,4 l steel fuel tank not only provides the rider with perfect knee contact, but also with a long range. Even when you ride as fast as you dare, thanks to its extremely economical engine.


The intricate engine design, state-of-the-art injection electronics and the close-ratio, 6-speed transmission not only help the KTM 125 DUKE to achieve impressive performance, but also extremely low fuel consumption. At the same time, thanks to the regulated catalytic converter, it produces only minimal emissions.

Spawned from the look and feel of “The Beast”, it’s no surprise that from the very first impression, the KTM 125 DUKE has a look about it that sparks fear in those against, rather than with it. But with a big-bike feel, steel fuel tank and various high-quality cast parts, you know that there’s nothing to fear once you’ve taken a seat.


As an absolute first in its class, the 125 DUKE boasts a glorious TFT display. This multicolor combination of relevant information presents all relevant data in a clear-cut, uncluttered way. As you rev the engine, the display bars change color, either spurring you on or telling you to back off when the engine’s still cold. […]


Different modes for the various assistance systems can be selected using an illuminated menu switch on the left side of the handlebar. It’s very simple and intuitive: “up” and “down” through the menu selection, select the desired menu item with the right button or go a step back with the left. Job done. Race on.


Form and function are integrated beautifully in the 125 DUKE. Take the LED headlight for example, a highlight in this bike’s design and a clear referral to the 1290 SUPER DUKE R. It combines optimal illumination of the near field with maximum light output. And the parking light, which consists of 20 LEDs, ensures that […]


At first you notice that LED headlight. That aggressive front. That predatory stance. When you come closer, you feel its steel fuel tank and various high-quality cast parts. In the end you realize that the design and production standards of this bike were set sky-high. Just like the KTM 1290 SUPER DUKE R, who’s little […]
