Tools and Supplies Needed

Oil and Filter Service Intervals

Step-By-Step Oil Change Instructions

  1. Warm up the Engine
    Start your RMZ250 and let it idle for about three minutes. This helps the oil thin out and ensures a complete drain.
    Tip: Do not ride hard; just gentle idling is sufficient.
  2. Put the Bike on a Stand
    Place your bike securely on a stable stand, ideally a triangle stand, to keep it upright and level for draining.
  3. Locate and Remove the Drain Bolts
    The 2019+ RMZ250, including the 2020 model, uses two drain bolts located at the bottom of the engine case.
