Regular oil changes are essential for maintaining the performance and longevity of your 2017 Honda CRF110F. This guide—proprietary to MotoSport.com—walks you through every step of the process, with specific model call-outs, tool requirements, and key precautions. Changing the oil is a straightforward maintenance task that any owner can perform with basic hand tools and a little know-how.

Tools & Supplies Needed

  • 17mm socket or wrench (for oil drain bolt)
  • Socket wrench or ratchet handle
  • Clean rags or shop towels
  • Drain pan (capacity to hold at least 1 liter of oil)
  • Rubber gloves (recommended for cleanliness and heat protection)
  • Replacement engine oil: Honda GN4 10W-30 or 10W-40 (approximately 1.1 US qt / 1.0 L)
  • Replacement sealing washer for the oil drain bolt (OEM recommended)
  • Torque wrench (to accurately set the oil drain bolt torque)
  • Funnel (optional, for easy pouring of new oil)
  • Honda service manual or owner’s manual (for reference)
  • Parts cleaner (for cleaning any spilled oil or debris)

Step-by-Step Oil Change Procedure

  1. Warm Up the Engine
    • Start the CRF110F and let it idle for 3–5 minutes so the oil thins and drains more thoroughly.
    • Turn off the engine and allow the bike to sit for 2–3 minutes. This helps the oil settle in the crankcase for a complete drain.
      Tip: Be cautious—the engine and exhaust will be hot.
  2. Park the Bike Safely
    • Place your bike on a firm, level surface and ensure it is secure on its kickstand.
  3. Remove the Oil Fill Cap/Dipstick
    • Twist off the oil fill cap/dipstick on the right side of the engine. Set it aside on a clean surface.
  4. Drain the Engine Oil
    • Position a drain pan under the crankcase.
    • Use your 17mm socket or wrench to carefully remove the oil drain bolt (located beneath the engine).
    • Warning: Do not remove the cam chain tensioner push rod bolt—it is a separate bolt near the drain bolt and can cause engine damage if removed by mistake.
      If you are unsure, consult your manual for correct identification.
    • Allow oil to completely drain. Pro tip: gently tilt the bike side-to-side to ensure all oil is evacuated.
  5. Check & Clean the Drain Plug and Sealing Washer
    • Examine the removed drain plug and sealing washer for wear or damage.
    • It is highly recommended to replace the sealing washer with a new OEM washer during each oil change to prevent leaks.
  6. Reinstall the Oil Drain Bolt
    • Install the drain bolt, along with the new sealing washer, by hand and then tighten with your socket wrench.
    • Use a torque wrench to set the bolt to 18 lbf·ft (24 Nm, 2.4 kgf·m) as specified by Honda.
  7. Refill Engine Oil
    • Place a funnel in the fill opening.
    • Pour in the recommended engine oil (Honda GN4 10W-30 or 10W-40), approximately 1.1 US quarts (1.0 liters) for the CRF110F.
    • Add oil slowly to prevent overfilling and spillage. The MotoSport.com team recommends using oil with a built-in filler spout for convenience.
    • Replace the oil fill cap/dipstick securely.
  8. Run the Engine and Recheck Oil Level
    • Start the engine and let it idle for 3–5 minutes.
    • Turn off the engine, let it settle for a minute, and then check the oil level with the dipstick (do not screw it in, just dip and read). The level should be at the upper mark—add oil if necessary but do not overfill.
    • Inspect around the drain bolt and fill cap for leaks.
  9. Properly Dispose of Old Oil
    • Transfer the used oil from your drain pan to a sealed container and bring it to an approved recycling center or automotive shop for disposal. Never dispose of oil in drains or the environment.

Specific Call-Outs for the 2017 Honda CRF110F

  • Oil Capacity: 1.1 US quarts (1.0 liters).
  • Drain Bolt Torque: 18 lbf·ft (24 Nm).
  • Correct Identification: The oil drain bolt is distinct from the cam chain tensioner push rod bolt. Double-check before removal to avoid engine damage.
  • Oil Screen/Filter: The CRF110F uses an internal oil screen rather than a traditional filter. Periodic inspection is advised, particularly if the bike is used in very dusty conditions.
    Consult your service manual for steps to check and clean the oil screen if desired, though it's not required at every oil change.
  • Dusty Riding Environment: If you ride in dusty or harsh environments, increase your oil change frequency as recommended by Honda.

Common Owner Questions

  • Should I use synthetic oil? Honda recommends using only JASO MA-certified motorcycle oil; synthetic or conventional is acceptable if it meets this specification.
  • Do I need to change a filter? There is no replaceable oil filter on the CRF110F, but the internal oil screen should be checked occasionally for debris.
  • What if I remove the wrong bolt? If you accidentally remove the cam chain tensioner push rod bolt, consult a professional before reassembling to avoid engine damage.
