Rieju RS2
Brake fluid capacity & service interval
The Rieju RS2 uses brake fluid with a capacity range between minimum and maximum values. Four configurations of the model are covered in the data.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| RS2 125 Matrix (2006-2011) |
|
| RS2 125 Naked (2006-2011) |
|
| RS2 50 Matrix (2006-2011) |
|
| RS2 50 Naked (2006-2011) |

Additional Notes
- All four RS2 variants covered across the 2006-2011 range share a hydraulic brake system, which uses pressurized fluid to transfer braking force from the lever or pedal to the caliper.
- The Rieju RS2 brake fluid capacity is expressed as a range rather than a fixed volume, with the correct level falling between a marked minimum and maximum on the reservoir.
- A between-min-and-max specification is typical for hydraulic brake reservoirs, where the fluid level naturally drops slightly as brake pads wear and the caliper pistons extend further outward.
- The RS2 range spans two engine displacements, 50cc and 125cc, across Matrix and Naked body configurations, yet all four share the same brake fluid level specification for normal use conditions.
- Normal use conditions apply uniformly across the Matrix and Naked trims in both the 50cc and 125cc variants, meaning no variant carries a separate severe-use interval or capacity distinction for the brake fluid system.
