View PageThe 2026 KTM 390 Adventure X in WHITE is built for riders who want one bike that can handle daily miles, backroad exploring, and weekends that turn onto gravel. Power comes from a liquid-cooled 398.7 cm³ single-cylinder, 4-stroke engine managed by Bosch EMS with RBW, paired with a 6-speed transmission. A steel trellis frame and WP APEX suspension help keep the ride composed, while KTM’s Offroad ABS supports confident braking when conditions get loose. A 5" LCD dash, USB-C port, and KTMconnect compatibility round out a practical cockpit for real-world adventure riding.
At the heart of the 390 Adventure X is KTM’s latest-generation LC4c platform: a 398.7 cm³, liquid-cooled, single-cylinder engine producing 45 PS and 39 Nm. Bosch EMS with RBW (ride-by-wire) manages the power delivery, and a 6-speed gearbox keeps it versatile across commuting speeds, open-road stretches, and slower technical sections.
The chassis is supported by WP APEX components—an open-cartridge 43 mm fork up front and a WP APEX Emulsion shock in the rear. Suspension travel is 200 mm front and rear, and the rear shock includes a preload adjuster to help tailor the bike for different loads and riding conditions.
KTM’s proven Offroad ABS technology is designed to help you use strong braking performance in the dirt with added control. From the rider’s seat, the 5" LCD display keeps key information clear at a glance, a USB-C port is fitted as standard, and KTMconnect allows smartphone connectivity for calls, music, and optional turn-to-turn navigation via the display.
The 390 Adventure X uses a 1-cylinder, 4-stroke, liquid-cooled engine with 398.7 cm³ displacement, tuned for real-world performance. Output is rated at 45 PS with 39 Nm of torque, and Bosch EMS with RBW helps deliver consistent throttle response. A 6-speed transmission gives the bike flexibility for city traffic, open roads, and slower off-pavement stretches.
Power is delivered through a 520 X-Ring chain. KTM specifies Motorex Formula 4T 15W/50 engine oil, and the listed CO2 emissions figure is 79 g/km.
A powder-coated steel trellis frame and bolt-on steel trellis subframe form the foundation of the 390 Adventure X, balancing stability with a nimble feel. Chassis geometry includes a 62.5° steering head angle, 99 mm trail, and a 1464 mm wheelbase. Ground clearance is 232 mm, supporting mixed-surface routes where obstacles and ruts are part of the plan.
Braking hardware comes from ByBre, with axial floating 2-piston calipers up front squeezing a 320 mm disc, and a 1-piston floating caliper at the rear with a 240 mm disc. Cast wheels measure 2.5 x 19" front and 3.5 x 17" rear—an adventure-friendly combination for pavement and gravel.
For comfort and control, the 390 Adventure X includes a Rally-style windscreen and offroad-focused footpegs. The footpegs are wide and robust, with two adjustable positions for standing or seated riding, and rubber inserts that can be removed when conditions get rough. Seat height is 825 mm, and the single-piece stepped seat is designed for easy removal to access the airbox and a small storage compartment underneath.
Fuel capacity is listed at 14 l (3.7 US gal), supporting longer rides between stops. KTM also fits a sturdy windshield design intended to provide an unobstructed view ahead, even when the bike gets dirty.
The cockpit centers around a 5" LCD dashboard, designed to keep rider information easy to read at a glance. A USB-C port is fitted as standard for on-bike charging. KTMconnect compatibility allows the bike to connect to your smartphone so you can make calls, listen to music, and use the optional turn-to-turn navigation app through the display.
KTM also includes a Premium Manufacturer’s Warranty: riders enjoy up to 4 years of coverage. To keep the warranty valid, regular services must be performed according to the service plan at an authorized KTM dealer.
Boasting the latest generation in LC4c engines, the KTM 390 ADVENTURE range muscles up with 399 cc, more power, smoother acceleration, and lighter overall weight than before.

What's an adventure without fuel range? The KTM 390 ADVENTURE X boasts a 3.69-gallon (14-liter) fuel capacity and exceptional fuel economy, making long jaunts into the faraway outdoors easy. What's more, the fuel tank represents a central element of the design and engineering, offering excellent ergonomics for riders of all sizes without sacrificing off-road handling.
The KTM 390 ADVENTURE X makes easy work of gravel tracks thanks in part to its low center of gravity, nimble handling, and 19" front wheel. However, its KTM's proven Offroad ABS technology allows riders to use full braking power in the dirt without compromising on fun.
The KTM 390 ADVENTURE X boasts cast wheels at each end with a 17" rear and 19" front, making it ideal for life on the street and when hitting gravel tracks.
With many years of development in the toughest terrain, the KTM 390 ADVENTURE X boasts WP APEX suspension with 205 mm of travel at each end. This results in a best-in-class handling package that is ready to tackle any adventure. Not only that but the WP APEX Emulsion shock absorber with preload adjustability provides tailored performance ideal for traveling long distances in tough conditions.
The KTM 390 ADVENTURE range features distinctive KTM-style bodywork and graphics, providing excellent ergonomics and an aggressive look inspired by KTM's vast Rally racing heritage. This can be seen in everything from the headlight mask to the front fender. The tank spoilers and rear side panels are slightly wider than the seat for optimized control when standing on the pegs, while the shape of the fuel tank is optimized to offer freedom of movement when tackling tricky technical terrain. A robust engine guard also makes its intentions known by protecting the engine and exhaust when venturing off the tarmac into the dirt.
An 5" LCD dashboard display adorns the cockpit of the KTM 390 ADVENTURE X, providing an array of rider-specific information at a glance. This means riders can focus on the road ahead, without any distraction. To top it all off a USB C port is also fitted as standard.
You'll no doubt hit some highways at some stage. Good thing, then, that the KTM 390 ADVENTURE range boasts a sturdy and efficient windshield. Thanks to its slim profile, the rider isn't obstructed when moving around the machine. It also offers an unobstructed view directly in front of the bike - even when covered in dirt.
Even on adventures, you want to stay connected. Thanks to the KTMconnect system, the KTM 390 ADVENTURE range connects to your smartphone, allowing you to make phone calls, listen to music, and use the optional turn-to-turn navigation app, all via the TFT display.
The KTM 390 ADVENTURE range features an ultra-lightweight yet extremely stable trellis 2-piece frame. This frame provides the backbone and is a major element accounting for its nimble handling and forgiving balance of flex and stiffness.
The KTM 390 ADVENTURE X is all about capability and comfort. It is designed to be an adventure machine, from its Rally-style windscreen, right down to its offroad-focused footpegs. All-day riding comfort, supreme offroad agility, and unmatched rider involvement make the KTM 390 ADVENTURE X a class leader when it comes to taking the path less traveled in complete control.
The KTM 390 ADVENTURE range features a single-piece stepped seat. The seat can be easily removed for access to the airbox and a small storage compartment underneath.
