To check the engine oil level, ensure the bike is on a level surface. Warm up the engine for a few minutes, then turn it off and wait for a minute. Use the sight glass on the right side of the engine to check the oil level, which should be between the minimum and maximum marks.
The recommended tire pressure for the KTM Duke 790 2019 is 33 psi (2.3 bar) for the front tire and 36 psi (2.5 bar) for the rear tire. Always check the tire pressure when the tires are cold.
The KTM Duke 790 2019 has adjustable suspension. For a smoother ride, reduce the preload on the rear shock and soften the compression and rebound damping on both the front forks and rear shock. Refer to the owner's manual for specific adjustments.
If the engine overheats, pull over safely and turn off the engine. Allow it to cool down before checking the coolant level. Ensure the radiator is not obstructed and that the cooling fan operates correctly. If the problem persists, consult a KTM service center.
The chain should be lubricated every 500 km (310 miles) or after riding in wet or dirty conditions. Check the chain tension and adjust it if the slack is more than 5-7 mm (0.2-0.3 inches) as per the user manual.
Use a high-quality ethylene glycol-based coolant that is silicate-free and mixed with deionized water in a 50:50 ratio for optimal performance. Check the owner's manual for specific recommendations.
To reset the service light, navigate to the service menu on the dashboard. Hold the up and down buttons simultaneously for about 10 seconds until the light resets. Refer to the manual for detailed instructions.
