Description

Merging all-road versatility and proven reliability with real-world performance, The 2025 KTM 390 ADVENTURE X makes heading on an adventure an everyday possibility. Powered by a proven 398 cc powerplant churning out 45 HP via a 6-speed gearbox, a class-leading chassis, and a 400 km tank range thanks to a 14.5-litre tank, it hits the road with purposeful intent. What's more, adjustable 43 mm WP APEX forks, 200 mm of wheel travel, OFFROAD MODE, and the option of 19/17" heavy-duty tubed spoked wheels, mean it is perfectly suited to the trail too.

KTM 390 power
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. Drawing from years of experience in the small engine game, the KTM 390 ADVENTURE X also features an improved gearbox and an optimized cylinder head. It is ready to adopt EURO 5.2 emission standards.

FRAME
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.

RALLY-INSPIRED BODYWORK
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.

WHEELS
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.
KTM 390 Adventure X FUEL TANK

FUEL TANK
What's an adventure without fuel range? The KTM 390 ADVENTURE X boasts a 14-liter fuel capacity and exceptional fuel economy, making long jaunts into the faraway outdoors easy. Moreover, the fuel tank represents a central design and engineering element, offering excellent ergonomics for riders of all sizes without sacrificing handling.
KTM 390 Adventure X DOMINATE THE DIRT OFFROAD MODE
6
DOMINATE THE DIRT OFFROAD MODE
When the tar road ends and the dirt track begins, KTM 390 ADVENTURE X riders can simply switch to OFFROAD MODE. This allows a certain rear-wheel slip, meaning muddy puddles or thick sand is easily navigated. More so, in OFFROAD MODE, OFFROAD ABS is also activated, meaning you can pull your best impressions locking up the rear wheel to slide into corners. OFFROAD MODE also maintains its settings in the event of stalling the engine or switching off your machine, meaning you're ready to go as soon as the engine fires up.
