- Drain pan
- Honda CRF450X oil filter
- Honda 20W-50 motor oil (or oil recommended in your owner's manual)
- Crush washers (also called sealing or ceiling washers) for both drain bolts
- O-rings for the oil filter cap and the transmission filler cap

Before You Start: CRF450X Model Call-Outs
- The 2013 CRF450X has separate engine and transmission oil compartments. You must change both fluids independently.
- Each drain bolt has a dedicated washer–replace these every oil change to prevent leaks.
- Do not confuse the engine and transmission drain plugs; improper filling can damage the engine or gearbox.
- Do not overtighten filter cover bolts or drain bolts—aluminum threads are easy to strip.
- Many owners slightly overfill the transmission side (950ml vs. the factory 750ml) to help protect the transmission; check your manual before doing this.
Step-By-Step Oil Change Instructions
-
Warm Up the Engine
- Start your bike and let it idle for 3–5 minutes. This helps thin the oil for better drainage.
- Turn off the engine and place the bike on a level surface or stand.
-
Remove Skid Plate/Engine Guard (if equipped)
- Use the appropriate socket or Allen wrench to remove the skid plate for better access to the drain bolts.
-
Drain the Engine Oil
- Locate the engine oil drain bolt on the left side of the stator case (not the bolt under the shifter/gear lever; that is for transmission oil).
- Place a drain pan underneath, then use your 10mm socket and ratchet to remove the bolt and washer.
- Let the oil completely drain out. Inspect drainage for metal debris (small flecks mean it's time to check your engine internals).
-
Drain the Transmission Oil
- The transmission oil drain bolt is located behind the shift lever.
- Use a 10mm socket to remove this bolt and washer, draining the transmission oil into the pan.
-
Remove the Oil Filter
- Use the 8mm socket to remove the oil filter cover bolts on the left engine side. Note that there may be two different length bolts, so track their placement.
- Carefully remove the cover without prying. Remove the spring and the old oil filter. Inspect the filter for metal filings or debris.
- Replace the filter cover O-ring if hardened or worn.
-
Install New Oil Filter
- Place the spring and new filter into the housing in the correct orientation (see owner's manual).
- Reinstall the cover bolts (do not overtighten; torque to approximately 9–10 Nm).
-
Reinstall Drain Bolts
- Install new crush washers on both engine and transmission drain bolts.
- Thread each bolt in by hand, then torque each to 16 Nm (about 12 ft-lbs).
-
Refill Engine Oil
- Remove the engine oil filler cap. With a funnel, fill with Honda 20W-50 engine oil. The general fill is:
- Engine oil: 0.7 – 0.8 liters with filter change (consult your manual for exact specification)
- Check the sight glass on crankcase cover for correct oil level. Do not overfill.
- Replace the filler cap with a new O-ring if necessary.
-
Refill Transmission Oil
- Remove the transmission filler cap and check plug.
- Use an approved wet clutch compatible motorcycle transmission oil.
- Slowly fill the transmission as per your owner's manual, generally up to the check bolt until oil gently runs out.
-
General fill for the CRF450X:
- Factory: 0.75 liters (750ml)
- Some riders fill up to 0.95 liters (945ml/1qt) for extra protection.
- Reinstall the check bolt with a new crush washer and torque to 10 Nm.
- Replace filler cap with new O-ring if needed.
-
Double-Check, Start, and Re-Check Levels
- Before starting, re-check that all caps and bolts are tight and all tools are clear of your work area.
- Start the engine and let it idle for 3–5 minutes.
- Shut off the engine and let it sit for 2 minutes, then re-check levels in both compartments and top off as needed.
-
Dispose of Used Oil Responsibly
- Bring used oil and filters to a recycling center or automotive parts store accepting oil waste.
CRF450X-Specific Tips and Warnings
- Always use new crush washers and O-rings to avoid leaks.
- Be very careful not to cross-thread or over-torque aluminum bolts—strip easily.
- Document your mileage/hours—Honda recommends oil changes about every 15 hours or after every six races for best engine health.
- Observe the oil you drain. Metallic flecks can indicate top end wear or major issues that may require further inspection.
