TM Racing SMX

Clutch fluid capacity & service interval

TM Racing SMX uses clutch fluid with a capacity range between min and max. Service intervals include 3 races or 12 months. The data covers 5 configurations.

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

Additional Notes

  • All five configurations across the TM Racing SMX lineup use a hydraulic clutch system, meaning the clutch is actuated by fluid pressure rather than a mechanical cable.
  • The fluid level specification for every configuration is expressed as a range rather than a fixed volume, with the reservoir kept between the minimum and maximum marks on the sight glass or reservoir body.
  • The 125 SMX, 250 SMX, and 300 SMX share an identical change interval of every 3 races under normal use conditions.
  • The 85 SMX carries two separate interval entries depending on use condition. Under normal use, fluid is changed every 12 months, while under competition use the interval shortens to every 3 races.
  • A 12-month calendar-based interval, as seen on the 85 SMX under normal use, is typically applied when a machine accumulates low or irregular operating hours, making mileage or event-count intervals impractical.
  • The race-count interval of 3 races, applied to the 85 SMX under competition use, aligns with the higher thermal and mechanical stress that hydraulic fluid experiences during competitive riding, which accelerates fluid degradation.
  • The displacement range across the SMX lineup spans from 85cc to 300cc, yet the fluid level specification method remains consistent across all variants, with no configuration specifying a fixed fill volume in milliliters or fluid ounces.
