Keeping your 2024 Honda CRF250R performing at its best means regularly changing the engine oil. This guide, proprietary to MotoSport.com, provides step-by-step instructions, the specific tools you’ll need, helpful tips, and call-outs unique to this model. Changing the oil on the CRF250R is straightforward and can be done in under 30 minutes with basic tools.

Tools & Materials Needed

  • 8mm socket (for oil filter cover bolts)
  • 6mm Allen/hex key (for drain plug)
  • Drain pan
  • Shop rags
  • Torque wrench
  • Funnel
  • New oil filter (Recommended: Honda OEM or Hiflo HF116)
  • Engine oil (Recommended: Honda GN4 10W-30; Capacity: 1.35 quarts or 1.3 liters for oil and filter change)
  • Gloves (optional, for cleanliness)

Important Model-specific Call-outs

  • No dipstick:– The 2024 CRF250R does not use a traditional oil dipstick. Instead, it has a sight glass on the side case to check oil levels. Refer to this to ensure proper oil fill after changing the oil.
  • Frequent changes recommended:– Honda recommends changing oil every 10 hours of engine time, especially under racing conditions.
  • Oil filter removal tip:– Remove both oil filter cover bolts incrementally and evenly to avoid warping or wedging the cover.
  • Draining tip:– Warm up your engine briefly beforehand. Warm oil drains faster and removes more contaminants.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Let the bike idle for 3-5 minutes to get the oil warm. This helps oil drain quickly and completely.
    • Turn off the bike and place it securely on a stand.
  2. Locate and Remove the Drain Plug
    • Using a 6mm Allen/hex key, locate the oil drain plug under the engine (at the bottom center).
    • Place the drain pan under the plug. Loosen and remove the plug.
    • Let the oil drain completely into the pan. Tilt the bike gently from side to side after initial flow slows to help remove all old oil.
  3. Remove the Oil Filter
    • Move to the right side of the engine.
    • Using an 8mm socket or wrench, remove the two bolts securing the round oil filter cover.
    • Pull the cover straight off. The old filter may stay on the bike or come out with the cover—be careful as oil may drip.
    • Remove the old filter and inspect the O-ring on the cover. Replace if damaged.
    • Wipe the area clean with a rag.
  4. Install the New Oil Filter
    • Lightly oil the rubber sealing ring of the new filter with fresh engine oil.
    • Place the new filter in the engine, then reinstall the cover, tightening both 8mm bolts evenly to avoid cover distortion.
  5. Reinstall the Drain Plug
    • Inspect the drain plug and crush washer (replace if damaged).
    • Reinstall the drain plug. Torque to manufacturer spec (Honda typically recommends 18 lb-ft, but check your manual).
  6. Add New Oil
    • Open the oil fill cap on the right side case.
    • Place a funnel in the fill hole. Pour in 1.35 quarts (1.3 liters) of 10W-30 engine oil for both oil and filter change. For oil only, use 1.25 quarts.
    • Replace and tighten the fill cap.
  7. Check the Oil Level
    • Let the bike sit upright (not on the stand) and observe the oil level through the sight glass.
    • Start the bike and let it idle for 1-2 minutes, shut it off, and allow oil to settle for one minute. Recheck the oil level. It should sit at or just below the upper line in the sight glass–add more oil if needed, but do not overfill.
      Note: Do not use a dipstick; only the sight glass for the 2024 model.
  8. Clean Up & Dispose Properly
    • Wipe away any spilled oil, ensure everything is tightened to spec, and properly dispose of the used oil/filter at a recycling center.

Extra Tips for the 2024 CRF250R Owner

  • Track oil change intervals using a log or clipboard for best engine care.
  • If your bike is raced or ridden in muddy/wet conditions often, change the oil more frequently.
  • Always use a high-quality oil filter—OEM is best for performance and fitment.
  • Check for leaks after running the engine post-change.

Regular oil and filter changes are possibly the best maintenance you can do for the long life of your 2024 Honda CRF250R. With these detailed steps, you can confidently handle the job yourself, ensuring peak performance on every ride.
