Model-Specific Call-Outs for 2026 Honda CRF50F

  • Oil change procedure has not significantly changed over recent CRF50F models, so prior generation instructions are applicable.
  • The oil capacity is approximately 0.6 US quarts (0.6 liters/600 mL), but always check via the dipstick as actual capacity can vary depending on residual oil during draining.
  • The engine oil drain bolt is located on the right side of the engine.
  • Do not remove the cam chain tensioner push rod bolt by mistake, as this may require dealer service to correct.
  • Honda recommends a drain plug with a magnet for added engine protection against metal shavings.

Step-by-Step Instructions

  1. Warm Up the Engine
    Start your bike and let the engine idle for 3–5 minutes. This allows the oil to thin and drain more completely.
    Safety tip: Turn the engine off before proceeding to drain oil.
  2. Prepare the Bike
    Park the motorcycle on a firm, level surface and ensure it is upright (use a stand if possible). Remove the oil fill cap/dipstick to help oil drain smoothly.
  3. Drain the Old Oil
    Place your oil drain pan under the engine. Using your socket wrench (usually 17mm), remove the oil drain bolt found on the right side of the engine crankcase.
    Important: Do not remove the cam chain tensioner push rod bolt—check your manual if unsure. Only remove the designated oil drain bolt.
  4. Enhance Drainage
    Once the oil drains, gently tilt the bike from side to side to ensure all oil is removed from the crankcase.
  5. Replace the Sealing Washer
    Remove the old sealing washer from the drain bolt. Install a new sealing washer to ensure a proper seal and prevent leaks.
  6. Reinstall the Drain Bolt
    Reinstall the drain bolt with the new washer. Torque the bolt to 18 lbf·ft (24 N·m) as specified in the owner's manual.
  7. Add New Oil
    Pour the new 10W-40 oil into the crankcase. Start with about 600 mL (0.6 qt), but do not overfill. Use a measuring cup for accuracy.
  8. Check Oil Level
    Reinstall the oil fill cap/dipstick, but do not screw it in. With the bike level, remove the dipstick and check the oil level. Add more oil if needed until the level reaches the upper mark.
  9. Start and Re-Check
    Start the motorcycle and idle for 3–5 minutes to circulate the oil. Shut off and wait 2–3 minutes for oil to settle. Check the oil level again with the dipstick and top up if needed.
  10. Inspect for Leaks & Clean Up
    Check around the drain plug and crankcase for oil leaks. Wipe off any oil spills, properly dispose of used oil and the old washer.

Tips & Reminders for the 2026 Honda CRF50F

  • Oil capacity can vary slightly; always fill until the dipstick reads full when the bike is upright, not just according to a set volume.
  • Consider a magnetic drain plug to help capture engine shavings for extra engine protection.
  • Never overfill; too much oil can cause engine problems.
  • Dispose of all used oil and materials properly to protect the environment.

Conclusion

Routine oil changes are straightforward and essential for your 2026 Honda CRF50F’s longevity. Follow these steps every 10–20 hours of riding or as specified in your owner’s manual, always using the correct oil type and quantities.
