01. Engine & Exhaust

Unrivalled torque
Unrivalled torque

Engine

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 22 kW (30 hp) for an extremely lightweight craftsmanship, it does just that. Thanks to the ingenious intake and exhaust system, the 38 mm throttle body and the meticulous fuel injection system, this strong stroker is ready to leave the rest of the city traffic behind at the twist of your wrist.

Power & Torque

A bike as compact and nimble as this one deserves to pack a solid punch. With 22 kW (30 hp) for an extremely lightweight craftsmanship, it does just that. Thanks to the ingenious intake and exhaust system, the 38 mm throttle body and the meticulous fuel injection system, this strong stroker is ready to leave the rest of the city traffic behind at the twist of your wrist.

Cylinder head

Just like the KTM 1290 SUPER DUKE R, the four valves in the cylinder head of the KTM 250 DUKE are actuated by two overhead camshafts and ultra-hard, carbon coated cam followers. The result is an ultra-reliable, long-lasting engine that produces next-level power.

Slipper clutch

Not only does the slipper clutch open when the engine back-torque becomes too high, it also assists when you open the throttle. The former prevents rear wheel chatter when braking sharply or decelerating – and gives the wheel just that bit of braking for a controlled rear wheel slide. The latter allows the clutch to be pulled and controlled with just one trigger-happy finger – saving you energy and offering greater control – just like the pros.

Ultimate exhaust system

Exhaust

The KTM 250 DUKE’s lightweight and precision-crafted exhaust system comprises of a side exhaust, link pipe and silencer. The three-chamber silencer has been positioned close to the bike’s overall center of gravity, improving balance and handling, whilst also delivering smooth, instant and beast-like power. Oh, and it looks angry as hell too.

Wheels

As light as they are stable, the 17-inch cast alloy racing wheels help you put the power down with confidence, utilizing a 110 mm wide tire at the front and an impressive 150 mm at the rear. Wrapped in premium rubber, the pro-spec tires will keep your KTM 250 DUKE glued to the road. They offer outstanding grip in both wet and dry conditions, as well as providing supreme durability, even for riders that know how to push tires to their absolute limits.

03. Bodywork & Graphics

LCD display

A 100% digital LCD display has everything you would expect from a state-of-the-art KTM motorcycle, including engaged gear, fuel gauge and service reminder information. It also comes with an RPM alert to indicate the optimum moment for up-shifting, just like they have on the supersport racing machines.

Predatory design
Predatory design

Design

At first you notice that aggressive front end. That predatory, READY TO RACE stance. When you come closer, you feel its steel fuel tank and multiple high-quality cast parts. In the end, you realize that the design and production standards of this bike were set sky-high. Just like its big brother, the KTM 1290 SUPER DUKE R, the KTM 250 DUKE looks like a naked, angry, untamed beast.

Headlight

With integrated Daytime Running Lights (DRL) consisting of 20 individual LEDs, this halogen headlight makes a bold statement, with its an unmistakable similarity to THE BEAST. Just get on and hunt them all - the KTM 250 DUKE invites you to do exactly that.
