Additional Notes

  • The Yamaha YH 50 Why (5XS0) uses a hydraulic brake system, meaning brake fluid is contained within a closed circuit and must be maintained between the reservoir's minimum and maximum level markers rather than filled to a fixed volume.
  • Under normal use conditions, the brake fluid level is scheduled for inspection every 6,000 km or every 12 months, whichever comes first.
  • A complete brake fluid change is specified at a 24-month interval under normal use conditions, regardless of distance traveled.
  • An initial service check of the brake fluid level is specified at 1,000 km, which is a separate and earlier inspection point than the recurring 6,000 km normal-use interval.
