Essential Maintenance Tips from the KTM Duke 390 Service
Manual
While the manual covers everything, some maintenance tips are especially useful for
regular upkeep and enhancing your riding experience.
Engine Oil and Filter Changes
The Duke 390’s engine thrives on clean, high-quality oil. According to the service manual,
changing the oil every 3,000 to 4,000 kilometers or every six months (whichever comes
