KTM SMR 450 2021 Owner's Manual

The recommended oil type for the KTM SMR 450 2021 is fully synthetic 10W-50 motorcycle oil. The oil change interval is every 15 hours of riding or as specified in the user manual.
To adjust the suspension settings, refer to the suspension adjustment knobs located on the front forks and rear shock. For off-road use, soften the compression and rebound damping. For track use, stiffen these settings. Always consult the user manual for detailed adjustment procedures.
If the engine won't start, check the following: ensure the kill switch is set to 'Run', check the fuel level, inspect the spark plug for fouling, and ensure the battery is charged. Additionally, verify that the fuel lines are clear and that the fuel pump is operational.
Regularly clean the chain with a chain cleaner and a soft brush. Lubricate it with a high-quality chain lubricant every 500 miles or after riding in wet conditions. Check for proper tension and adjust using the chain adjusters if necessary.
To replace the air filter, first remove the seat and side cover. Unscrew the air filter cover and carefully remove the old filter. Install the new filter by reversing the removal steps, ensuring it is properly seated and sealed.
Adjust the clutch lever by loosening the locknut and turning the adjuster screw on the lever perch. Set it to a comfortable reach, ensuring there is a slight free play, and tighten the locknut.
A spongy brake feel may indicate air in the brake lines. Bleed the brake system to remove air bubbles. Check for brake fluid leaks and ensure the fluid level is adequate. Replace the brake fluid if it appears contaminated.
To check and adjust the valve clearance, remove the valve cover and use a feeler gauge to measure the clearance between the cam lobes and the valve shims. Adjust as necessary by replacing the shims with the correct thickness. Refer to the service manual for specific clearance values.
The recommended tire pressures for the KTM SMR 450 2021 are typically 29 psi for the front tire and 32 psi for the rear tire for road use. Adjust pressures according to load and riding conditions. Always check the user manual for precise specifications.
For off-season storage, clean the motorcycle thoroughly, change the oil, and fill the fuel tank with a stabilizer. Disconnect the battery and store it separately. Elevate the bike to prevent flat spots on the tires and cover it to protect from dust and moisture.
