01. Engine & Exhaust
The KTM 390 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 really packs a punch and with 32 kW (44 hp) it’s one of the most powerful options out there for A2 riders. Thanks to the ingenious intake design and the meticulous fuel injection system, the KTM 390 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 32 kW (44 hp) and a dry weight of just 149 kg, we did it justice. Thanks to the ingenious intake and exhaust system, the 46 mm throttle body and the meticulous fuel injection system, this strong stroker is ready to leave the rest of the traffic behind at the twist of your wrist.
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.
It's the guarantee of a smooth throttle response, more than simply the absence of a throttle cable. The KTM 390 DUKE's ride-by-wire ensures perfect delivery of the readily available and gut-wrenching torque. It also electronically translates the throttle commands of the rider into throttle valve positions, perfectly suited to the riding conditions, making this the perfect crossover bike for both road and circuit riding.
Just like the KTM 1290 SUPER DUKE R, the four valves in the cylinder head of the KTM 390 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.
The intricate engine design, state-of-the-art injection electronics and close-ratio, 6-speed transmission not only help the KTM 390 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.
The KTM 390 DUKE matches all the A2 driver´s license requirements and thanks to its high power-to-weight ratio, it’s one of the most dynamic options out there for new riders.
The KTM 390 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.
