For a 2003 KTM 450 SX, the engine typically requires about 1.5 quarts (1.4 liters) of oil. It's important to check the owner's manual for the specific oil capacity and recommendations for oil type. Always ensure the bike is on level ground and check the oil level using the dipstick or sight glass after filling. Regularly changing the oil is crucial for maintaining engine performance and longevity.
