Included are specific tips for the 2026 CRF110F and critical points to ensure a smooth oil change every time.
Tools and Supplies Needed
- 10mm or 12mm ratchet and socket (check your drain bolt size; Honda standard is usually 12mm, but confirm with the 2026 model)
- 17mm socket (some models, especially 2019+, use a 17mm drain bolt)
- Torque wrench (to ensure proper tightening of the drain bolt)
- Oil drain pan
- OEM Honda oil 10W-30 (1.1 US qt, or 1.0 liter; must be rated for wet clutch use)
- New sealing washer for the oil drain bolt
- Funnel (optional, but recommended for easy pouring)
- Clean rags or paper towels
- Nitrile or latex gloves (optional, for clean hands)
Steps to Change the Oil
-
Warm up the engine: Run your CRF110F for 3-5 minutes to get the oil warm; this helps it drain faster and more completely. Turn the engine off and let it sit for 2-3 minutes so the oil can settle.
Tip for 2026 CRF110F: Modern fuel-injected engines, like in the 2026 model, warm up quickly, but don't overheat. Monitor for steady idle before shutting off. - Set up your workspace: Park the bike on a firm, level surface, such as your garage floor or an outdoor pad. Make sure the bike is secure and upright.
- Remove the oil fill cap/dipstick: This helps the oil drain quickly.
- Position the drain pan: Place an oil drain pan directly under the crankcase drain bolt, located on the lower right side of the engine.
-
Remove the oil drain bolt: Use a ratchet and 17mm socket (check your bolt size) to loosen and remove the drain bolt. Oil will begin to drain immediately.
- Important: Do not remove the cam chain tensioner push rod bolt, which is nearby. If removed by mistake, seek dealer assistance.
-
Drain the oil completely: Allow oil to flow out until it slows to a drip. Gently tilt the bike side to side to ensure all oil drains.
Call-out for the CRF110F: This model features an internal oil screen that should be checked periodically. For routine changes, a full removal isn’t required, but a more in-depth inspection is recommended every few oil changes or after riding in especially dirty conditions. - Replace the sealing washer: Remove the old sealing washer from the drain bolt and install a new one to prevent leaks.
- Reinstall and torque drain bolt: Screw in the oil drain bolt by hand and then use a torque wrench to tighten to 18 lbf–ft (24 N–m, 2.4 kgf–m). Don’t overtighten; aluminum engine cases can strip easily.
-
Pour in new oil: Using a funnel or the bottle’s pour spout, add approximately 1.1 US qt (1.0 L) of 10W-30 motorcycle oil (wet-clutch safe).
Don’t overfill. Go slowly and check the level frequently. Oil quantity remains consistent for the CRF110F across generations so the 2026 should match 1.0L capacity.
- If you installed a new oil screen or just performed an initial oil change, expect the oil to stay remarkably clean after just a few minutes of running.
- Reinstall the fill cap/dipstick.
- Start the engine: Let it idle for 3-5 minutes again. This circulates the oil and fills all passageways.
- Check oil level: Turn the engine off, let oil settle for 2-3 minutes. Remove dipstick, wipe, reinstall without screwing, remove, and check oil level. Level should be in the crosshatch area or upper mark. If needed, add oil in small amounts.
- Check for leaks: Inspect the drain bolt and crankcase area for leaks. If you see oil, stop and retighten the bolt slightly to proper spec.
- Dispose of old oil properly: Pour into a sealed container and bring to an approved recycling center. Don’t dump oil in the trash or down drains.
Special Call-Outs for the 2026 Honda CRF110F
- Internal oil screen: In addition to regular oil changes, there is an internal oil screen on the CRF110F which should be checked every few oil changes or if you notice persistent debris in drained oil. The 2026 model continues this design. Removal requires side cover removal, not routine for every oil change but important for long-term maintenance.
- Drain bolt location: Be careful not to confuse the drain bolt with the cam chain tensioner push rod bolt nearby. Doing so may require a professional fix.
- Oil type: Ensure all replacement oil is rated for wet clutch systems to prevent clutch slippage and ensure component longevity. Regular automotive oil is not appropriate.
- Torque specs: The drain bolt torque has not changed with the 2026 model; continue to use 18 lbf–ft (24 N–m).
- Capacity remains identical: 1.0 liter of oil is standard. Overfilling by even small amounts can hinder engine breathing.
Quick Recap
- Warm up, drain, replace washer, fill with exactly 1L of 10W-30 oil, check and correct your level, and look for leaks.
- Always use wet-clutch motorcycle oil and never substitute with auto engine oil.
- Check your internal oil screen every few changes for peace of mind.
