Engine & Exhaust
Engine: A state-of-the-art, liquid cooled, single-cylinder, four-stroke 373.2 cc engine powers this agile machine perfectly into KTMs world of ADVENTURE. The engine is equipped with an electric starter and achieves impressive peak power with incredibly punchy torque. Twin overhead camshafts, four valves and electronic fuel injection are integral to the KTM 390 ADVENTUREs outstanding power and together with a balancer shaft, deliver the highest levels of smoothness. Its lightweight and compact construction facilitates straight intake channels, allowing for a shortened distance for the intake air to flow into the combustion chamber, as well as to the two catalytic converters. Besides the faster movement of air and gases, this also allows the engine to warm up faster. Additionally, the two catalytic converters and the fuel tank ventilation system (EVAP system) improve emission values and prevent fuel vapors from being released into the environment, making the KTM 390 ADVENTURE extremely eco-friendly and compliant with strict exhaust emission standards.
Slipper Clutch: The slipper clutch is a unique feature that saves power and helps in slides. It opens when the engine back-torque becomes too high, preventing annoying rear wheel chatter when braking sharply or decelerating and gives the wheel just that little bit of braking for a controlled rear wheel slide. It also closes with the force of the clutch springs when the throttle is opened, allowing the clutch to be pulled with one finger, which saves energy when riding.
Ems/ride-By-Wire: The 390 ADVENTURE is fitted with a state-of-the-art engine management system featuring the most modern electronic fuel injection system with a 46 mm throttle body. Instead of the throttle valve in the electronic injection system being controlled by a conventional throttle cable, the KTM 390 ADVENTURE uses a ride-by-wire process. With the help of electronic sensors, twisting the throttle grip activates the throttle valve through the use of a servo motor. It electronically translates the throttle commands of the rider into the optimum throttle valve position for the current riding situation and for the most linear power delivery.
Piston: The 89 mm bore piston is DLC coated for extra durability. It performs a stroke of 60 mm, which results in a displacement of 373.2 cc and produces a compression ratio of 12.6:1. The crown is cooled by the oil spray nozzle, while the piston uses a continuous, low-friction, nicasil-coated aluminum wet bushing with open-deck design.
Cylinder Head: State-of-the-art DOHC (Double Overhead Camshaft) technology. The four valves in the cylinder head of the KTM 390 ADVENTURE are actuated, via durable finger followers, by two overhead camshafts. This design is one of the preferred performance solutions of many offroad models, including the successful KTM 1290 SUPER ADVENTURE. It is not only renowned for its extreme reliability, but also offers low friction, thanks to the ultra-hard DLC coating on the finger levers - a solution that makes this engine super reliable, even when pushing for longer at high RPM.
Gearbox: The KTM 390 ADVENTURE is fitted with a robust 6-speed sequential gearbox. The gear ratios fit perfectly to the power band of the 373.2 cc engine and allow you to smoothly select the perfect gear, whether it be flowing street rides or more challenging offroad escapes.
A2 License: The KTM 390 ADVENTURE matches all the A2 drivers license requirements.
