Tools and Supplies Needed
- 8mm socket
- 10mm Allen wrench
- Torque wrench
- Drain pan
- Measuring cup (for precise oil volume)
- Rags and rubber gloves

- Contact cleaner (optional, for cleaning up spills)
- Replacement engine oil (Honda HP4 synthetic recommended)
- New oil filter and O-rings
- Owner's manual (for reference to specs and diagrams)
Important Call-Outs for the 2023 Honda CRF450X
- 2023 CRF450X uses separate engine and transmission oils. Be sure to use the correct plugs and chambers for each.
- The engine oil fill port is on the left side. Use a narrow funnel since the port is smaller than older models.
- The recommended capacity for the engine side is typically about 1.00 quart (950ml), but always confirm in your manual for your specific year and riding conditions.
- Synthetic oil without moly (like Honda HP4, gold bottle) is favored, especially for less aggressive clutch use.
- Always replace the oil filter with every oil change for optimal engine protection.
Step-by-Step Oil Change Instructions
-
Start the bike and warm it up for 1-2 minutes.
This reduces oil viscosity, allowing it to drain more completely and carrying away suspended particles as it flows out. Don’t skip this step.
-
Shut off the engine and secure the bike upright.
A bike stand makes this much easier, but anything that ensures a stable, upright position will work.
-
Remove the skid plate (if equipped), then locate and clean the drain bolts.
Using a rag, clean around the engine oil drain bolt (the larger bolt on the frame’s left down below) and the transmission drain bolt (on the lower right). Removing dirt ensures nothing falls into your oil.
-
Place the drain pan under the engine. Remove the engine oil drain bolt with a 10mm Allen wrench.
Allow oil to drain fully—this may take a few minutes. Inspect the oil for metal shavings as a check for abnormal wear.
-
Optional: Remove the transmission drain bolt and drain trans oil.
If you are changing both engine and trans oil, repeat the process for the transmission side. CRF450X often benefits from slightly overfilling the transmission to 950ml for additional protection, but consult your manual for specs.
-
Remove and replace the oil filter.
The filter is located on the engine's right side within a bolted cover (held by two distinct bolts).
- Take out the bolts (use your 8mm socket).
- Remove the old filter and O-rings. Clean the inside of the filter area.
- Install a new oil filter and replace O-rings as needed.
- Reinstall the cover and torque bolts as specified in your manual.
-
Replace the drain bolts and torque to spec.
Use your torque wrench and follow Honda’s recommended specs (usually in the range of 18–22 ft-lb for most bolts, but confirm in your owner’s manual).
-
Refill engine oil through the small fill port (left side).
Use a funnel to add the precise amount specified in your service manual. Pour slowly and avoid overfilling.
- Tip: Lean the bike slightly to help access the fill port. Avoid spilling oil on the engine.
-
Replace the fill cap, start the bike, and let it idle for about 30 seconds.
This helps circulate the fresh oil and allows you to check for leaks.
-
Check oil level and top off if necessary.
Shut off the engine and wait a minute, then use the dipstick or inspection window on the engine side to ensure proper oil level. Add more oil if below the recommended mark.
Additional Tips and Reminders
- Change engine oil every 10–15 hours of riding (or more frequently if you ride hard or in dusty conditions).
- Dispose of old oil responsibly at a recycling center or automotive store.
- Check the owner’s manual for updates or changes to recommended oil types, capacities, and maintenance intervals specific to the 2023 CRF450X.
- Inspect your drain plug for a crush washer—replace it if worn for best sealing.
- Always monitor for any leaks after your first post-change ride.
