Additional Notes

  • Across all Yamaha RS Vector variants and model years covered, brake fluid capacity is expressed as a level range rather than a fixed volume. The specification calls for fluid to sit between the minimum and maximum marks on the reservoir, which is standard practice for hydraulic brake systems where the exact fill volume depends on component wear and system displacement.
  • Every RS Vector configuration listed carries a 24-month change interval under normal use conditions. A time-based interval of this kind reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time and lowers its boiling point regardless of how many miles or hours the vehicle has accumulated.
  • The RS Vector ER (RS90R) spans model years 2005-2010 across three separate specification rows, all sharing the same hydraulic brake system fill method and 24-month service interval throughout that range.
  • The RS Vector GT (RS90GT) appears across four distinct model year groupings from 2006-2011, with consistent brake fluid specifications across all of them. The overlap in years between consecutive rows, such as 2006-2008 and 2008-2009, reflects how Yamaha model year designations can bridge calendar years.
  • The RS Vector LTX GT (RS90LTGT) and RS Vector LTX (RS90LT) variants both enter the specifications beginning with the 2008-2009 model year grouping, later than the base RS Vector and Mountain trims, which appear as early as 2005-2006.
  • The RS Vector LTX (RS90LT) has a gap between the 2009-2010 row and the 2012-2016 row, with no 2010-2011 entry present. The 2012-2016 row represents the longest single model year span for any individual RS Vector LTX entry in the specifications.
  • The RS Vector Mountain and RS Vector Mountain SE (both RS90M) share the same model code designation. The Mountain SE appears only in the 2006-2007 grouping, while the standard Mountain variant has entries for both 2005-2006 and 2006-2007.
  • The base RS Vector carries three separate model code suffixes across its listed entries: RS90 for 2005-2006, RS90N for 2006-2007, and RS90R for 2008-2009, before transitioning to RS90P beginning with the 2010 model year grouping.
  • The RS Vector RS90P entry covers the 2010-2019 span, the widest single year range among all entries in the specifications. Despite the extended range, the brake fluid service specification remains unchanged at a reservoir level fill between min and max with a 24-month change interval under normal use.
