Gas Gas EX

Clutch fluid capacity & service interval

Gas Gas EX uses clutch fluid with a capacity range of min to max. Service intervals require a change every 12 months. The data covers 6 configurations.

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

Additional Notes

  • All Gas Gas EX variants listed here use a hydraulic clutch system, meaning clutch engagement is controlled through fluid pressure rather than a mechanical cable.
  • Across all EX configurations in these specifications, the correct fluid level falls between the reservoir's minimum and maximum marks rather than at a fixed volume, which is typical for hydraulic clutch reservoirs where level is verified visually.
  • Every EX variant listed carries a 12-month change interval under normal use conditions, meaning annual replacement applies regardless of mileage or hours of operation.
  • The EX 450F appears under two separate entries: a 2020-only configuration and a second configuration starting in 2021, both sharing the same fluid level specification and 12-month change interval despite being listed as distinct variants.
  • The EX 250 carries a start year of 2021, making it the only variant in these specifications that does not share a 2020 introduction year with the rest of the EX lineup.
  • The EX lineup spans two-stroke displacement classes (EX 250, EX 300) alongside four-stroke classes (EX 250F, EX 350F, EX 450F), yet the hydraulic clutch fluid level specification and service interval are consistent across both engine types.
