Maintenance / Coolant

Checking the Coolant

1. Place your motorcycle on a firm, level surface.

2. Hold your motorcycle in an upright position.

3. Check that the coolant level is between the UPPER and LOWER level marks on the reserve tank cover.

If the coolant level is dropping noticeably or the reserve tank is empty, you likely have a serious leak. Have your motorcycle inspected by your dealer.


Adding Coolant

If the coolant level is below the LOWER level, add the recommended coolant until the level reaches the UPPER level mark.

Add fluid only from the reserve tank cap and do not remove radiator cap.

1. Remove the reserve tank cap and add fluid while monitoring the coolant level.

  • Do not overfill above the UPPER level mark.
  • Make sure no foreign objects enter the reserve tank opening.

2. Securely reinstall the cap.


Removing the radiator cap while the engine is hot can cause the coolant to spray out, potentially scalding you.

Always let the engine and radiator cool down before removing the radiator cap.


Changing Coolant

Have your dealer change the coolant unless you have the proper tools and are mechanically qualified.
