Kawasaki KFX, KSF / KSV

Brake fluid capacity & service interval

Kawasaki KFX, KSF / KSV models utilize brake fluid with a capacity range defined by minimum and maximum levels. Service intervals require a change every 12 months. The data covers 8 configurations.

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

Additional Notes

  • Across the KFX and KSF/KSV lineup, brake fluid level is expressed as a reservoir fill range rather than a fixed volume, meaning the specification calls for fluid to sit between the minimum and maximum marks on the reservoir rather than a measured quantity added during service.
  • The Kawasaki KFX 400 / KSF 400 covering 2003-2006 carries only the reservoir level specification with no change interval listed, distinguishing it from all other models in the lineup where a 12-month change interval accompanies the level guidance.
  • A 12-month change interval applies to the KFX 250 Mojave / KSF 250-A18 for the 2004 model year, the KFX 450R / KSF 450 for 2008-2014, the KFX 50 variants, the KFX 700 V / KSV700 for 2003-2009, and the KFX 90 / KSF 90 from 2007 onward.
  • The 12-month interval is a calendar-based service cycle rather than a mileage or hour-based threshold, meaning brake fluid replacement is tied to elapsed time under normal use conditions regardless of operating frequency.
  • All entries in the lineup are designated under normal use conditions, meaning the intervals and level specifications apply to standard operating environments without a separate severe-use schedule listed for any model.
  • The KFX 450R / KSF 450 specifications are split across two separate year groupings, 2008-2009 and 2010-2014, both carrying identical brake fluid specifications, reflecting a model continuity in hydraulic brake system servicing across those production years.
  • Two distinct KFX 50 entries appear in the specifications: one covering the KSF 50 designation for 2006-2009 and another under the KFX 50 designation from 2013 onward, both sharing the same between-min-and-max level requirement and 12-month change interval.
  • The KFX 700 V / KSV700 covers 2003-2009 and represents the largest displacement model in the lineup, yet the brake fluid specification structure mirrors that of smaller-displacement models, with the same reservoir-based level method and annual change interval.
