SYM RS-21

Brake fluid capacity & service interval

SYM RS-21 uses Brake fluid with a capacity range of min to max. Service intervals include Normal. The data covers 2 configurations.

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

TypeSpecifications
RS-21 125 (2005-2010)
  • Use: Normal
  • Between min and max.
RS-21 150 (2005-2010)
  • Use: Normal
  • Between min and max.

Additional Notes

  • Both the RS-21 125 and RS-21 150 operate with a hydraulic brake system, meaning brake fluid is contained within a closed circuit of lines, a master cylinder, and calipers rather than a mechanical cable arrangement.
  • The specified fill level for both engine variants falls between the reservoir's minimum and maximum markers, which is the standard operating range for hydraulic brake fluid in normal use conditions.
  • The 125 and 150 displacement variants share the same brake fluid level specification across the 2005-2010 model years, with no differentiation in the fill range between the two configurations.
