Tools & Supplies Needed

  • 8mm and 10mm socket or wrench
  • 32mm Allen head/socket
  • Torque wrench
  • Oil change kit: includes oil filter, oil filter seal, drain plug seal
  • 2 quarts of oil: Pro Honda GN4, HP4 (with molybdenum or equivalent), or equivalent quality oil

  • Clean funnel
  • Gloves and safety glasses
  • Service manual (always recommended for specs and checks)

Step-by-Step Oil Change Guide for the 2017 Honda CRF450X

  1. Warm Up the Engine
    Start the engine and let it idle for 3-5 minutes. This will thin the oil, allowing for more complete drainage.
  2. Secure the Bike
    Place your bike on a suitable stand to ensure it sits upright. This step prevents spills and improves access to drain points.
  3. Remove the Skid Plate (If Equipped)
    Use the 8mm or 10mm socket/wrench to remove the three bolts securing the skid plate. Once removed, set it aside. Clean any built-up dirt or debris from the area before proceeding.
    Specific callout: The 2017 CRF450X and CRF450RX have a similar skid plate attachment system with three bolts–one on each side and one in the middle. Always ensure the area around the drain plug is free of debris before removal to prevent contamination.

  4. Locate and Remove the Drain Plug
    The oil drain plug is accessed using a 32mm Allen head/socket. Before loosening, clean around the plug with contact cleaner and a shop towel.
    Tip: Place your oil drain pan under the plug to catch waste oil. Carefully unscrew the drain plug and allow all oil to drain completely.
  5. Remove and Replace the Oil Filter
    Locate and remove the oil filter cover using the correct socket or wrench (typically 8mm or 10mm). Pull out the old filter using a shop towel to avoid burns. Insert the new filter from your oil change kit, making sure the orientation matches the removed filter.
    Replace the filter seal/gasket if your kit includes one.

  6. Inspect and Replace the Drain Plug Seal
    Review the drain plug seal for signs of wear or compression. Replace it with a new one if provided—most oil change kits include this part. Wipe the plug clean and reinstall, tightening it to manufacturer torque specifications (see your manual for exact values).

  7. Refill with Oil
    Use a clean funnel to pour in your engine oil. For the 2017 model, use 0.74 US qt (0.70 L) when changing the filter; 0.71 US qt (0.67 L) without filter change.
    Owner call-out: While the CRF450R and RX for 2017 have a combined engine/transmission fluid design, the CRF450X retains separate compartments:
    • Engine oil: 0.74 US qt (0.70 L) with filter
    • Transmission oil: 0.69 US qt (0.65 L) recommended, but some suggest running a full quart for higher-speed use to avoid potential failures. Always check your manual and local expert recommendations for your specific riding conditions.

  8. Reinstall the Skid Plate
    Place the skid plate back in position and secure with all three bolts. Confirm all torque specs using a torque wrench and your service manual.
  9. Start and Check for Leaks
    Fire up the engine and let it idle for a minute. Shut it off and inspect for leaks near the drain plug, filter cover, and around the skid plate. Address any issues before riding.
  10. Check Oil Level and Top Off
    Allow the bike to sit level for a minute, re-check the oil level using the sight glass or dipstick, and add oil if necessary. Do not overfill.
  11. Record Your Maintenance
    Log the date, hours, and oil type used. Regular oil change intervals are critical—Honda recommends every 10-15 hours of operation, but many owners prefer 8-10 hours for extra peace of mind. Monitor your riding style and conditions to tailor your schedule.

Model-Specific Notes & Call-Outs for the 2017 CRF450X

  • The 2017 Honda CRF450X uses separate engine and transmission oils, unlike the 2017 CRF450R and CRF450RX, which use a single oil system. Double-check which engine you have if uncertain.
  • Always reference your service manual for oil specifications, torque values, and maintenance record-keeping.
  • Popular alternative oils for the engine: Amsoil 10W-40, Maxima Extra Synthetic, Shell Rotella T 5W-40.
  • For the transmission, many owners bump up to a full quart for extra reliability if riding at higher sustained speeds.

Regular oil changes remain one of the most effective and affordable ways to maintain peak performance from your Honda CRF450X. Keep up with the schedule, always use quality oil and OEM or high-quality filters, and never skip key steps. Ride safe and enjoy your time on the track or trail.
