01. Engine & Exhaust

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 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.<br />Additionally, the KTM RC 390 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.

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.

Cylinder head
Exactly like they did in the RC8 R, the four valves in the cylinder head of the 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 up the throttle. The former prevents annoying 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 – which saves energy when riding.


Ride-by-wire
It’s the guarantee of a smooth throttle response, more than simply the absence of a throttle cable. The RC 390’s ride by wire ensures perfect application 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.


Exhaust
The RC 390 is equipped with a side exhaust, including link pipe and silencer.
