KTM 390 Adventure X 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.
