The KTM 390 ADVENTURE takes exploration further by merging all-road versatility and proven reliability with real-world performance. Built around a compact 373 cc single-cylinder powerplant with a capable, lightweight chassis and class-leading electronics, the KTM 390 ADVENTURE encourages you to find new frontiers with the unmatched capability and excitement you'd expected from a KTM ADVENTURE machine. Featuring an updated design for 2022, the KTM 390 ADVENTURE is now also visually aligned with the Dakar winning KTM FACTORY RALLY machines.

; Engine & Exhaust

Engine: A state-of-the-art, liquid cooled, single-cylinder, four-stroke 373 cc engine powers this agile machine perfectly into KTM's world of ADVENTURE. Twin overhead camshafts, four valves and electronic fuel injection are integral to the KTM 390 ADVENTURE's outstanding power and together with a balancer shaft, deliver the highest levels of smoothness. Its lightweight and compact construction facilitates straight air intake channels, allowing for a shortened distance for air to flow into the combustion chamber, and beyond for gas flow 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 the strict EU5 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 the little finger, which saves energy when riding.
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 ccm 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.
