KTM 400
Clutch fluid capacity & service interval
KTM 400 uses clutch fluid with a capacity range between min and max. The service interval is 12 months. The data covers 6 configurations.

Additional Notes
- The KTM 400 lineup across the EXC, MXC, and SX variants from 2000-2007 all use a hydraulic clutch system, meaning clutch engagement is controlled through fluid pressure rather than a mechanical cable.
- A hydraulic clutch reservoir has a minimum and maximum level marked on the reservoir body or sight glass, and the fluid level is to be maintained between those two markers rather than filled to a fixed volume.
- All six configurations share a 12-month change interval under normal use conditions, meaning the fluid is replaced on a calendar-year basis regardless of mileage or hours of operation.
- The 12-month interval reflects the hygroscopic nature of brake and clutch fluid, which absorbs moisture from the atmosphere over time, lowering its boiling point and degrading performance even when the system has seen limited use.
- The 400 EXC spans two distinct specification entries covering 2000-2004 and 2005-2007, while the 400 MXC and 400 SX each split across 2000-2004 and a shorter subsequent range, indicating model year groupings within the same fluid specification.
- Despite the EXC, MXC, and SX representing different riding disciplines — enduro, cross-country, and motocross respectively — the clutch fluid level and change interval specifications are identical across all three variants for the covered years.
