Cleveland CycleWerks FXx / FXR
Brake fluid capacity & service interval
Cleveland CycleWerks FXx / FXR models utilize brake fluid with a capacity range between min and max. Service intervals include checking every 15 hours and changing every 12 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| FXx / FXR 125 (2017- ) |
|
| FXx / FXR 110 (2015-2016) |

Additional Notes
- The Cleveland CycleWerks FXx / FXR 110 covers the 2015-2016 model years, while the FXx / FXR 125 begins with the 2017 model year, meaning the two engine variants do not share a common production period within the specified data.
- Both the 110 and 125 variants specify a hydraulic brake system, which means brake fluid is contained within a closed circuit of master cylinders, lines, and calipers rather than a mechanical linkage arrangement.
- The fill specification for both variants is expressed as a level range rather than a fixed volume, meaning the reservoir must be maintained between the marked minimum and maximum indicators rather than filled to a precise measured quantity.
- The FXx / FXR 110 carries a brake fluid check interval of every 15 hours under normal use conditions, which ties the inspection schedule to accumulated operating time rather than calendar time alone.
- A 12-month change interval is specified for the FXx / FXR 110 under normal use conditions. Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time, which lowers its boiling point and reduces braking effectiveness, making a time-based replacement interval a standard practice regardless of mileage.
- The FXx / FXR 125 carries no check or change interval in the specifications, whereas the FXx / FXR 110 carries both a 15-hour check and a 12-month change interval, representing a direct difference in the service data available between the two engine variants.
