A state-of-the-art, liquid cooled, single-cylinder, four-stroke 373.2 cc engine powers this agile machine perfectly into KTM’s 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 ADVENTURE’s 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.

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.

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.

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.

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.

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. 

The KTM 390 ADVENTURE matches all the A2 driver´s license requirements.

The KTM 390 ADVENTURE features a lightweight, precision-crafted exhaust system, comprising of a stainless steel header pipe and pre-muffler, which flow perfectly into a slim silencer. The silencer is shaped by a compact and light aluminum sleeve that has been positioned close to the bike’s overall center of gravity to improve balance and handling. It aids in delivering instant, smooth power and is specifically designed to not affect the rider’s movement on the bike. Two catalytic converters are integrated in the header pipe and pre-muffler, effectively reducing exhaust emissions.

Similar to the race proven frame of the KTM 450 RALLY, the KTM 390 ADVENTURE features an ultra-lightweight, yet extremely stable trellis frame. It exceeds all requirements for stability and controllability and is the backbone of this nimble adventurer. The forgiving balance of flex and stiffness, combined with a wheelbase of 1,430 +/- 15.5 mm (56.3 +/- 0.6 in) and a 26.5 degree steering head angle, clearly suggest an offroad oriented layout. It is also the basis of its outstanding straight-line stability and precise and agile steering behavior.

The removable, steel trellis subframe is fixed to the main frame with 4 screws. It was developed to be compact and lightweight, but strong enough to carry a passenger and luggage, while negotiating the tough conditions that can be expected when adventure riding.

The die-cast, open-lattice swingarm is a signature element of the KTM ADVENTURE range. It is precisely manufactured with an optimized stiffness, while still offering excellent flex characteristics. The rear shock links directly onto the swingarm, reducing complexity and parts, while also enhancing the feeling of the bike’s behavior for the rider. The relatively long swingarm provides enough space for any suitable offroad tire.

With many years of development in the toughest terrain, the KTM 390 ADVENTURE draws on WP’s renowned racing experience for a great handling package that is ready for more adventure. The fully adjustable WP APEX suspension in the front and rear, work together perfectly with the chassis to provide comfort, control and the clearance to venture down more challenging roads. 

The WP APEX 43 mm upside-down fork was originally developed for enduro riding and is the absolute leader when it comes to suspension in this class. It features a spring on both sides, but each fork leg has a separate function: compression damping is fitted on the left side, while rebound is on the right. This means the forks can easily be adjusted with the twist of a dial on the top of the forks. Due to high-quality materials and a state-of-the-art production process, the WP APEX 43 mm fork – with 170 mm of travel – has outstanding response and damping characteristics.

The triple clamp is developed for a 26.5 degree steering head angle. It is also possible to change the height of the handlebar with different mounts available in the KTM PowerParts catalogue.

The cutting-edge WP APEX shock absorber finds its way into the nimble chassis of the KTM 390 ADVENTURE. It provides 177 mm of travel and is ideal for traveling long distances in tough conditions. Thanks to an adjustable spring preload and rebound damping, it can be fine-tuned to different situations, balancing typical KTM performance with all day riding comfort.

Extra robust cast wheels specifically designed for demanding terrain feature on the KTM 390 ADVENTURE. The 19” front wheel and 17” rear wheel, both fitted with tubeless CONTINENTAL TKC 70 tires, provide excellent performance on the street, while still offering ample grip and control when taking an offroad detour home.<br /><br />Front: 100/90-19 tubeless CONTINENTAL TKC 70,  2.5 inch rim<br /><br />Rear: 130/80-17 tubeless CONTINENTAL TKC 70, 3.5 inch rim

High-quality BYBRE brakes featuring a large 320 mm front brake disk and a 230 mm rear disk work perfectly with a 4-piston radially mounted front caliper and a 2-piston floating rear caliper, to provide the ideal mix of control and stopping power. In addition, a 2-channel ABS system made by BOSCH guarantees the highest performance standard when conditions get a bit trickier.

The fuel tank is a central element of the design and engineering mastery of this daily adventurer. Its shape offers excellent ergonomics, with a narrow knee area that provides great control and even fits taller riders. It has an impressive <strong>14.5</strong> liter fuel capacity and together with its exceptional fuel economy, is set for more than 400 km of non-stop exploring on a full tank.

As on the bigger-displacement KTM ADVENTURE machines, the KTM 390 ADVENTURE is fitted with a high-end, tapered aluminum handlebar that importantly, provides a comfortable riding position and maximum control. The left side features an easily accessible menu switch for the TFT display and for the selection of various different modes and connectivity features. Simply flick "up" and "down" through the menu, select the desired setting with the right button or go a step back with the left.

The two-part seat is positioned for comfort and control on long rides, at an accessible seat height of 855 mm (33.7 in). The rider’s seat is narrower in the front, making it even easier to reach the ground. The seat cover provides a tested mix of grip and easy movement, while the foam ensures the ride stays comfortable - motivation to keep riding more and more. The seat can be easily removed for access to the airbox and a small storage compartment. 

The wide and robust foot pegs come directly from the offroad models. They were developed for all day riding, standing or seated, for street or offroad boots. They have rubber inserts, which provide more comfort when riding on the street and can be easily removed for more grip when heading off the beaten track.

The KTM 390 ADVENTURE’s windshield is an efficient deflector. It has a profile that allows the rider to move around the bike freely and offers an unobstructed view directly in front of the bike, even when covered in dirt. It can also be mounted in a lower or higher position to suit the rider´s size or needs. Two windshields of different heights can be ordered from the KTM PowerParts catalogue.

As minimal as possible and as much as needed. The KTM 390 ADVENTURE features a distinctive KTM-style bodywork, providing excellent ergonomics and an aggressive look inspired by the rally bikes. Ready for adventure, the bodywork is produced in color to help keep its appearance looking fresh, even after scratching. The tank spoilers and rear side panels are slightly wider than the seat for good control and also to reduce wear and tear on the seat. The shape of the fuel tank is optimized to offer the rider freedom of movement and the best control. The headlight mask is as reduced as possible, taking design cues from KTM’s rally bike generation to create a slim, lightweight front end. A low front fender assists with good aerodynamics and keeps spray to a minimum when travelling on the road, while a robust engine guard protects the engine and exhaust when venturing off the road into the dirt.

State-of-the-art LED lights are used as the main headlight and taillight. LED lights offer great illumination and visibility and are compact, so they help reduce the overall volume of the motorcycle.

A state-of-the-art, full-color TFT display adorns the cockpit of the KTM 390 ADVENTURE. The display's configuration automatically adapts to variations in ambient light. For the best use of power, the rev counter blinks when it’s time to shift. The 5‘’ display is easy to read and the main information is arranged in such a way that you can immediately see it. The rider can also easily select which information they would like on the screen via the multi-functional menu switch on the handlebar.

KTM develops electronic rider aids that provide more control and better performance for riders of all levels of ability, with the intention of enhancing the fun in all conditions.

The MTC (Motorcycle Traction Control) is a lean-angle sensitive traction control system that reacts immediately the instant rear wheel rotation speed becomes disproportionate to the riding situation. In mere milliseconds, MTC reduces engine output with an extremely smooth, barely perceptible intervention at the throttle valves until slippage is reduced to optimum proportions for the selected ride mode and current angle of lean.

Riding adventure is about traveling long distances and venturing into the unknown, so having a bike that backs you up in extreme situations is very important. Regular ABS is developed specifically for the street, therefore an offroad ABS function has been added to improve braking control in offroad situations. In this mode, ABS is deactivated on the rear wheel, while ABS activation on the front wheel is reduced. This means riders can lock up the rear wheel, allowing them to steer the rear end into corners. It also prevents over regulated front wheel braking, or the opposite of too much front brake pressure, ensuring the best stopping power in the dirt.

KTM’s cornering ABS system allows riders to always use the full power of their brakes, while the system adjusts brake pressure to match the lean angle of the motorcycle for safer and more predictable braking across a wider range of conditions and scenarios. It can be turned off for offroad conditions.

With the KTM MY RIDE system, a smartphone can be tethered to the bike, allowing you to make phone calls, listen to music and use the optional turn-to-turn navigating app, all while keeping the adventure going.
