Frequency & Prep Recommendations
- Change interval: It's recommended to change the engine oil every 2.5 to 15 hours of ride time, depending on track/race intensity. Always refer to your owner's manual for specific recommendations as usage varies.

Detailed Steps to Change Oil on a 2023 Honda CRF450R
-
Warm up the Engine
- Start and idle the bike for about 1-2 minutes. Warm oil drains more thoroughly and suspends debris for better removal.
-
Remove the Skid Plate (if equipped)
- Using your 10 mm hex head socket, remove the three bolts securing the skid plate (left, right, and bottom) and set the plate aside.
-
Position Drain Pan & Remove Drain Plug
- Place the oil pan beneath the engine. Use your 10 mm Allen wrench to loosen and remove the drain plug, taking care as hot oil can flow quickly. Be sure to inspect the drain plug washer/O-ring; replace if worn or damaged to prevent leaks.
-
Remove the Oil Filler Cap
- Unscrew the oil filler cap (top of engine) to improve oil flow as it drains.
-
Allow Oil to Fully Drain
- Let oil drain completely for several minutes. Tipping the bike gently side to side (while stable) can help flush out remaining oil.
-
Remove Oil Filter Cover & Oil Filter
- Use your 8 mm socket/T-handle to remove the oil filter cover bolts. Noteworthy for the 2023 CRF450R: The lower bolt is longer than the upper bolt; remember this for reinstall.
- Hold the cover as you remove bolts, as a spring beneath may push it outward.
- Carefully pull out the spring and old filter.
- Inspect and clean: Check the filter O-ring/gasket and replace if nicked or swollen. Wipe out the filter housing with a clean lint-free rag, removing any debris or flakes.
-
Lubricate New Filter and Reinstall
- Apply a thin coat of fresh oil to the new filter's O-ring and the cover's O-ring. This helps with sealing and prevents sticking next service.
- Insert the spring, followed by the new oil filter (correct orientation – open end facing out as per your manual), then place the cover back and install both bolts (long bolt at the bottom).
- Torque bolts to spec; check your owner's manual for exact values, but typically 7-9 Nm for cover and 18-24 Nm for drain plug (confirm for your model).
-
Install Drain Plug
- Replace the washer or O-ring on the drain plug if needed. Thread drain plug in by hand first to avoid cross-threading, then tighten to specified torque.
-
Add Fresh Oil
- Using a funnel, pour in the recommended quantity and type of engine oil. The common fill for a 2023 CRF450R is around 0.85L (0.9 qt), but always check your manual for the precise volume.
- Install filler cap.
-
Check Oil Level
- Start the engine and let it idle for 1 minute. Shut it off and wait a minute, then check the oil level as per the sight glass or dipstick instructions in your owner's manual. Add oil if needed to reach the correct level.
-
Clean Up & Inspect
- Clean any oil residue on engine or frame. Double-check for leaks around the drain plug and filter cover.
- Dispose of old oil and filter properly.
- Reinstall skid plate if equipped.
2023 Honda CRF450R-Specific Callouts
- Bolt Length for Oil Filter Cover: Lower bolt is longer than the upper; incorrect installation may cause cover or gasket to warp.
- Crush Washer/O-ring Inspection: Always check the drain plug washer; reusing a damaged one is a common source of leaks.
- First Oil Change on New Engines: Honda recommends changing at 2.5 hours for brand new engines (after break-in period).
- Torque Specs: Always follow the torque values for your bike—over-tightening can damage threads or crush components; under-tightening can lead to leaks or plug loosening.
Final Tips
- Consult your 2023 Honda CRF450R owner's manual for oil type recommendations and precise quantities.
- Keep records of all oil changes for warranty and resale value.
- Use only quality, motorcycle-specific oil and OEM or high-quality aftermarket filters for best results.
- Routine, meticulous oil changes are the best insurance against premature engine wear and trackside letdowns.
