THE SPAWN OF THE BEAST
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.
01. Engine & Exhaust
A1 Power
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.
Cylinder head
Just like the 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.
GRITTY GROWL
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.

PERFORMANCE DAMPING
UPSIDE - DOWN FORK
The KTM 125 DUKE comes as standard with ultra-lightweight, high- performance upside-down WP forks. These forks not only perform above expectations when pushed to the limits, but are also nice and easy to maintain. This makes them perfect for all aspects of riding, from relaxed cruising to hammering around on closed circuits and everything in between.
SHOCK ABSORBER
Thanks to its progressive 162 mm spring, the KTM 125 DUKE will perform in any environment you can throw at it. The preload is adjustable, so you can count on well-balanced suspension whether you’re riding solo or two-up, with or without luggage, on road or on track. The choice is yours.
PRO ALLOYS
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 125 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.
STOPPING POWER
BRAKES
A high-tech BYBRE braking system works in perfect harmony with the advanced ABS, providing riders with firm, controlled stopping power when they need it most. With a 300 mm brake disc on the front,
paired with a 230 mm disc on the rear, the KTM 125 DUKE delivers exceptional pro-level stopping power, and you know what they say: “braking harder makes you faster!”.
SUPERIOR RANGE
FUEL TANK
The shapely 10.5 I fuel tank of the 125 Duke not only provides the
rider with perfect knee contact, but also with a range of substantially
more than 300 km even when ridden on the edge, thanks to the economic engine.
