01. Engine & Exhaust

Engine
The KTM RC 390 engine not only delivers bountiful torque and punchy 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 (43.5 hp) it’s the sportiest option out there. Thanks to the ingenious intake design and the meticulous fuel injection system, the KTM RC 390 is ready to leave the rest of the city traffic behind at the twist of a wrist.


Cylinder head
Exactly like they did in the RC8 R, the four valves in the cylinder head of the KTM RC 390 are actuated by two overhead camshafts and ultra-hard, carbon coated cam followers, providing reliability and longevity despite the engine’s high power output.


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.


Ride-by-wire
It’s the guarantee of a smooth throttle response, more than simply the absence of a throttle cable. The KTM RC 390’s ride by wire ensures perfect delivery of the readily available and plentiful 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 track and road riding.

Power & Torque
A bike as compact and nimble as this one, deserves to pack a solid punch. With 32 kW (43.5 hp) and a dry weight of just 170 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.

Injection
The intricate engine design, state-of-the-art injection electronics and the close-ratio, 6-speed transmission not only help the KTM RC 390 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.


Exhaust
The compact, three-chamber silencer is positioned close to the bike’s overall center of gravity. This helps keep the motorcycle centrally balanced and easy to maneuver in the tight and twisty urban streets.
