The recommended tire pressure for the KTM Adventure 390 2021 is 29 psi for the front tire and 32 psi for the rear tire.
It is recommended to change the oil every 4,500 miles (approximately 7,200 kilometers) or every year, whichever comes first.
The KTM Adventure 390 2021 requires a synthetic 10W-50 motorcycle oil that meets JASO MA2 specifications.
To adjust the suspension, locate the adjusters on the front forks and rear shock. Use the appropriate tool to change the settings based on your riding preferences and load. Consult the owner’s manual for specific instructions.
Remove the seat to access the airbox cover. Unscrew the airbox cover and remove the air filter. Clean the filter with an air filter cleaner, rinse, dry, and re-oil before reinstalling.
Locate the brake fluid reservoir on the handlebars for the front brake and near the rear brake pedal for the rear brake. Check the fluid level through the sight glass and ensure it is between the minimum and maximum markers.
The correct chain tension is 5-7 mm of slack at the midpoint between the front and rear sprockets. Adjust as needed using the chain adjusters on the rear swingarm.
To reset the service light, navigate to the settings menu on the TFT display, select 'Service', and follow the prompts to reset the service interval.
To winterize your motorcycle, clean it thoroughly, change the oil and filter, fill the fuel tank and add a fuel stabilizer, remove the battery and store it in a warm place, and cover the bike to protect it from dust and moisture.
To improve fuel efficiency, maintain proper tire pressure, ensure regular maintenance like oil and air filter changes, avoid aggressive acceleration, and reduce excess weight on the bike.
