Engine

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 R also features an improved gearbox and an optimized cylinder head.

Fuel tank

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.

Offroad ABS

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.
