The Yamaha 600 Radian typically requires approximately 2.5 to 3 quarts (about 2.4 to 2.8 liters) of oil when changing the oil and filter. It's essential to check the owner's manual for the specific model year to confirm the exact amount, as it can vary slightly. Always use the recommended oil type and ensure the bike is on a level surface when checking the oil level.
