Changing the oil in your 2024 Honda CRF450RL is a critical part of maintaining peak performance and long engine life. Follow this MotoSport.com proprietary guide for a safe, simple, and effective oil change tailored to your bike's specifications.

Tools & Supplies Needed

  • 10mm Allen key (for the drain plug)
  • 10mm and 8mm sockets with ratchet (for the skid plate, seat, and side cover)
  • Torque wrench
  • Oil drain pan
  • New Honda oil filter (refer to your parts manual for the correct part number)
  • High-quality motorcycle engine oil (Honda recommends 10W-30 API SJ or higher)
  • Replacement O-rings (as needed for the drain plug and oil filter cover)
  • Shop rags
  • Funnel
  • Gloves (recommended for protection)

Preparation

  • Warm up the engine for a few minutes. This allows contaminants to suspend in the oil, improving drainage.
  • Turn off the engine and let the bike cool for a minute. Place the bike on a stable stand for easy access.

Step-by-Step Oil Change Instructions for the 2024 CRF450RL

  1. Remove Skid Plate
    Use your 10mm socket or wrench to remove the three bolts holding the skid plate–one on each side and one underneath. Set the plate and hardware aside.
    Tip: Removing the skid plate provides access to the drain plug and prevents oil splash-back.
  2. Locate and Remove the Drain Plug
    The oil drain plug is located on the underside of the engine and requires a 10mm Allen key. Position the oil drain pan underneath before carefully loosening and removing the plug.
    Watch for hot oil; let the oil drain completely.
  3. Replace the Drain Plug O-ring (As Needed)
    Inspect the drain plug O-ring for wear or damage. Replace if necessary. Tip: While Honda recommends changing O-rings at every oil change, frequent changers may do this every 2–3 services if the O-rings remain in good condition.
  4. Remove and Replace the Oil Filter
    Locate the oil filter cover on the side casing. Use your 8mm or 10mm socket to remove the bolts securing the cover.
    Gently remove the old oil filter; a small spring sits behind the filter, so be careful not to lose it.
    Clean the filter cover and surrounding area for a good seal.
    Install the new oil filter, making sure the rubber ring on the filter sits facing the cap, and position the spring correctly in its recess.
    Replace the cover and tighten evenly.
  5. Reinstall the Drain Plug
    Clean the drain plug and threads. Reinstall using your 10mm Allen key, and torque to the manufacturer's specification (consult your owner's manual for exact torque values).
  6. Refill with New Oil
    Remove the oil fill cap and insert a funnel.
    Add 1.2 liters of 10W-30 API SJ (or higher) oil. Avoid overfilling.
    Reinstall the fill cap securely.
  7. Check Oil Level
    Start the engine, idle for a few minutes, then shut it off and let settle. With the bike upright, check the oil level via the dipstick or oil level window. Add more oil if necessary.
    Do not overfill, as this can harm the engine.
  8. Reinstall Skid Plate and Clean Up
    Reattach the skid plate and bolts. Dispose of used oil and filter according to local regulations.

Model-Specific Callouts and Tips for 2024 Honda CRF450RL Owners

  • Oil Change Interval: Honda recommends changing the oil every 600 miles (or sooner for aggressive riding conditions).
  • Filter Orientation: Always ensure the rubber ring side of the filter faces the cap, and the spring is seated correctly behind the filter. This is critical for proper oil circulation.
  • O-Rings: Inspect O-rings every change. Replace if cracked, flattened, or deteriorated. Skipping this can cause leaks.
  • Careful Torquing: The CRF450RL—s aluminum threads can strip if bolts are over-tightened. Always use a torque wrench per manual values.
  • Oil Choice: Stick with Honda's recommended viscosity and specification for long engine life. Avoid automotive oil as it may lack the necessary additives for wet clutch performance.
  • Skid Plate Removal: Do not skip this step; oil will splash on the plate and create a mess if left on.

Additional Maintenance During Oil Change

  • Clean the air filter (removing the seat as needed; see owner's manual for air filter care).
  • Check for coolant and brake fluid condition.
  • Inspect for leaks around gaskets and case covers.

Proper, regular oil changes are essential to keep your 2024 CRF450RL running at its best. MotoSport.com has all the necessary parts and fluids to complete this job with confidence—ensure every ride starts smooth and finishes strong.
