Why the 390 Adventure X

6 highlights
01 KTM 390 Adventure X — KTM 390 power

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.

02 KTM 390 Adventure X — FRAME

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.

03 KTM 390 Adventure X — RALLY-INSPIRED BODYWORK

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.

04 KTM 390 Adventure X — WHEELS

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.

05 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.

06 KTM 390 Adventure X — DOMINATE THE DIRT OFFROAD MODE

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.
