Yamaha YZF-R125

Brake fluid capacity & service interval

Yamaha YZF-R125 brake fluid capacity is between min and max. Service intervals include checks at 1000 km and 10000 km or 12 months, with fluid changes every 24 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Yamaha YZF-R125 hydraulic brake system does not specify a fixed fluid volume. The fill level is defined by the reservoir's minimum and maximum marks rather than a measured capacity in milliliters or liters.
  • For the 2008-2018 model years under normal use conditions, the brake fluid change interval is set at 24 months, which is a time-based interval independent of mileage accumulation.
  • Under normal use, the 2008-2018 configuration also carries a fluid level check interval of every 10,000 km or 12 months, whichever comes first, meaning the level inspection occurs more frequently than the full fluid replacement.
  • An initial service check at 1,000 km is specified for the 2008-2018 years, applying only to that early break-in period and not recurring at subsequent intervals.
  • The 2019 and later configuration retains the 24-month fluid change interval under normal use, keeping the replacement schedule consistent with the earlier generation despite being a separate specification entry.
  • The 2019 and later specification does not include a periodic kilometer-based level check interval, whereas the 2008-2018 entry lists a 10,000 km or 12-month check alongside the 24-month change.
