KTM 690 Duke
Brake fluid capacity & service interval
KTM 690 Duke brake fluid capacity ranges between min and max. Service intervals include 1000 km checks, 24 month changes, 20000 km or 24 month changes, and 10000 km or 12 month checks. The data covers 6 configurations.

Additional Notes
- Brake fluid level across all listed 690 Duke and 690 Duke R configurations is specified as sitting between a minimum and maximum marker, which is the standard reservoir-based measurement method for hydraulic brake systems rather than a fixed volume fill quantity.
- The 2008-2012 690 Duke carries a check interval of every 1000 km alongside a 24-month change interval. The 1000 km check figure is notably short compared to later generations and aligns with the kind of early-ownership monitoring typical of initial service schedules on hydraulic systems.
- For the 2013-2015 690 Duke and 690 Duke R, the specification combines a distance threshold of 20000 km with a 24-month time limit for the change interval, meaning whichever condition is reached first would trigger a fluid change under normal use.
- The 2008-2012 generation does not carry a combined distance-and-time change trigger in the same format as the 2013-2015 rows. The change interval for that earlier generation is expressed solely as a 24-month period with no accompanying kilometre figure.
- Starting with the 2016-2018 690 Duke and 690 Duke R, a periodic check interval of 10000 km or 12 months is reintroduced alongside the 24-month change interval. This separates the inspection cadence from the replacement cadence, which the 2013-2015 specification does not do.
- The 2019 690 Duke shares the same brake fluid specification structure as the 2016-2018 model, with a 10000 km or 12-month check interval and a 24-month change interval, indicating continuity in the hydraulic brake service schedule across those years.
- Brake fluid in hydraulic systems absorbs moisture over time, which lowers its boiling point. The time-based 24-month change interval present across all generations reflects this degradation mechanism, which occurs regardless of distance travelled.
