MZ/MuZ SM-SX-RT 125

Brake fluid capacity & service interval

MZ/MuZ SM-SX-RT 125 uses brake fluid with a capacity range between min and max. Service intervals require a change 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 MZ/MuZ SM-SX-RT 125 brake fluid specification applies to the hydraulic brake system across all three variants: the RT 125, SM 125, and SX 125.
  • All three variants share the same model year coverage, spanning 2000-2008.
  • Rather than a fixed volume fill, the brake fluid level is expressed as a range between a minimum and maximum mark, which is standard for hydraulic brake reservoirs where the level drops gradually as brake pads wear.
  • A 24-month change interval is specified under normal use conditions for the RT 125, SM 125, and SX 125. Time-based intervals like this are common for brake fluid because the fluid absorbs moisture over time, lowering its boiling point regardless of mileage.
  • The RT 125, SM 125, and SX 125 all carry identical brake fluid specifications, with no variation in fill guidance or change interval across the three variants for the 2000-2008 period.
