01. Engine & Exhaust

Engine
The KTM 125 DUKE engine not only delivers arm-wrenching torque and hair-raising acceleration, but also good manners in everyday use, all with outstanding fuel economy. This lightweight, compact engine packs a good punch too, with a respectable 11 kW (15 hp). Thanks to the ingenious intake design and the meticulous fuel injection system, the KTM 125 DUKE is ready and waiting to tear-up the streets and the circuits alike.


Power & Torque
A bike as compact and nimble as this one, deserves to pack a solid punch. With 11 kW (15 hp) it is right for entry level enthusiasts. Thanks to the ingenious intake and exhaust system, the 33 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 125 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.


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


Exhaust
The KTM 125 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.
