Tools and Supplies Needed

  • 8mm allen key (for drain plug and skid plate bolts)

  • New oil filter (Honda Part Number: 15412-MEN-671)
  • Motorcycle-specific engine oil (e.g., Honda GN4 10W-30)
  • New sealing washer (recommended)
  • Funnel
  • Shop rags
  • Gloves

Important Model-Specific Notes

  • The oil drain plug uses an 8mm allen key and is located on the bottom of the engine beneath the skid plate.
  • The oil filter cover is secured by two 8mm bolts.
  • The recommended oil type is 10W-30 JASO MA-rated motorcycle oil. The OEM choice is Honda GN4.
  • Warming up the engine before draining ensures a more complete and faster oil flow.
  • Replace the sealing washer on the drain plug every oil change to prevent leaks.
  • Tip the bike gently side-to-side once drained to expel any trapped oil from engine cavities.
  • Check the owner's manual for volume specifications, typically around 1.0 liter when changing the oil and filter.

Step-by-Step Instructions

  1. Warm Up the Engine
    Start the bike and let it idle for a few minutes. Warm oil drains more quickly and completely.
  2. Remove the Skid Plate (if fitted)
    Use an 8mm allen key to remove the two bolts securing the skid plate. Set the plate and bolts aside.
  3. Position Oil Catch Pan
    Slide the oil catch pan beneath the drain plug at the bottom of the engine.
  4. Remove Drain Plug
    Using the 8mm allen bit, remove the oil drain plug. Allow all oil to drain. Inspect and replace the sealing washer if needed.
  5. Remove Oil Filter
    Loosen the two 8mm bolts on the oil filter cover. Carefully remove the cover and gasket. Pull out the old filter. Make note of the orientation of the filter so you can install the new one the same way.
  6. Drain Remaining Oil
    With the drain plug and oil filter out, tip the motorcycle gently side to side to make sure the last drops of oil leave the engine. Clean any residual oil from the mounting surfaces.
  7. Install New Oil Filter
    Lightly oil the new filter's o-ring. Insert into place. Install the filter cover and tighten the two 8mm bolts evenly. Ensure the gasket seats properly.
  8. Replace Drain Plug
    If using a new sealing washer, slip it on the plug. Start the plug by hand to prevent cross-threading, then torque snugly (consult your owner's manual for the specified torque value).
  9. Refill with Oil
    Insert the funnel into the fill port on the right side case. Pour in the recommended amount and grade of oil. Common fill amount is around 1 liter with a filter change. Check the owner's manual for your exact capacity. Do not overfill.
  10. Check for Leaks and Oil Level
    Start the engine and let it run for 1-2 minutes while watching for leaks at the drain plug and oil filter area. Stop the engine and allow the oil to settle. Check the oil level using the engine's sight glass or dipstick and top up as necessary.
  11. Reinstall Skid Plate
    Replace the skid plate (if applicable) and securely fasten with the mounting bolts.
  12. Dispose Old Oil Properly
    Pour the used oil into a suitable container and take it to a recycling center or auto parts store with oil recycling services.

Specific Tips for 2022 Honda CRF250RX Owners

  • The engine–s oil-changing design uses a single drain bolt and an external filter cover for ease of access—avoid overtightening bolts to prevent damaging aluminum threads.
  • Side-standing and gently rocking the bike helps ensure all dirty oil is expelled from internal passages.
  • Always use a genuine or high-quality aftermarket filter to ensure correct pressure and flow.
  • Consult your owner–s manual regarding oil quantity—adding too much oil can cause engine damage.
  • Honda recommends using a fresh sealing washer (crush washer) with every change for leak-proof sealing.

Final Reminders

  • Record your service in the maintenance log for warranty and resale purposes.
  • If you ride in extreme conditions (racing, dust, mud), shorten oil change intervals for best engine protection.
  • If you have any questions, consult your 2022 Honda CRF250RX owner's manual or reach out to MotoSport.com technical support.
