If you own a 2020 Yamaha TTR110, regular oil changes are critical for peak engine performance and longevity. This guide, proprietary to MotoSport.com, walks you through the tools needed, specific steps, and important call-outs for this make and model. Even if you're new to dirt bike maintenance, following these directions will ensure a professional-quality oil change every time.

Tools & Supplies Needed

  • 12mm wrench or ratchet (for drain bolt)
  • Oil catch pan or drip pan
  • Funnel (clean, to avoid oil spills)
  • Rag or shop towel
  • Measuring cup (for accurate oil fill)
  • Recommended oil: 10W-40 Yamalube or equivalent motorcycle-specific engine oil
  • New crush washer for drain bolt (recommended, not always required)
  • Dipstick (already on the bike, but you'll be using it to check your oil level)
  • Gloves (optional but helps keep your hands clean)

Preparation

  • Run the engine for 5-10 minutes before changing the oil. This ensures the oil is warm, thin, and will drain out smoothly.
    Tip: Warm oil carries away more contaminants.
  • Turn off the bike and secure it upright and level on a stand or the kickstand.
  • As a best practice, protect your workspace with cardboard or a drip tray under the engine.

Step-by-Step Oil Change Instructions

  1. Locate the oil drain bolt.
    On the 2020 Yamaha TTR110, the drain bolt (12mm) is on the bottom of the engine case.
  2. Position your oil catch pan.
    Place the catch pan directly beneath the drain bolt to catch draining oil.
  3. Remove the drain bolt.
    Using the 12mm wrench, carefully remove the bolt. Allow all oil to drain out. This can take several minutes.
    Caution: The oil may be hot.
  4. Inspect the old oil and the drain bolt.
    Check for metal shavings or debris. Inspect the bolt and washer; replace the crush washer if damaged or worn.
  5. Reinstall the drain bolt.
    Once the oil is fully drained, reinstall and hand-tighten the drain bolt. Then, snug it (do not overtighten) with the 12mm wrench.
  6. Add new oil.
    - Remove the oil fill cap/dipstick.
    - Using the funnel, pour in 28 fluid ounces (approximately 0.85 quarts or 828ml) of 10W-40 motorcycle oil.
    - Pour slowly to avoid overfilling.
    Call-out for TTR110: There is no oil filter to replace on this model, making the process straightforward.
    Note: A measuring cup or clear oil jug helps you pour the precise amount, since overfilling can cause problems like leaks or engine blow-by.
  7. Check oil level.
    - Stand the bike upright and insert the dipstick, but do not screw it in.
    - Remove and inspect the oil level on the stick. It should be between the low and high marks.
    - Top off as needed, being careful not to exceed the maximum mark.
    Tip: After filling, start the bike and let it idle for 1-2 minutes. Shut it off and wait a few minutes, then recheck the oil level. This accounts for oil circulation and settling.
    Caution: Overfilling may lead to engine damage or leaks; draining some oil is possible by loosening (not fully removing) the drain bolt and letting excess out if needed.
  8. Clean up.
    Wipe any spilled oil with a rag. Dispose of the used oil properly – take it to a recycling center or a local auto parts supplier that accepts used oil.
    Environmental tip: Never dump oil into drains or the environment.
  9. Final checks.
    With the bike running, inspect the drain bolt area for leaks. Turn the bike off and recheck the oil level after a few minutes.
