Shop parts for a 2026 Yamaha TTR110 Dirt Bike.

Changing the oil in your 2026 Yamaha TTR110 is an essential part of routine maintenance that ensures a long and smooth life for your dirt bike. This guide, proprietary to MotoSport.com, will walk you through every step, from the tools you’ll need to specific tips for this model. Even though changes on the TTR110 have remained consistent for years, it’s important to check for any updates relevant to your specific year, including the 2026 model.

Tools and Supplies Needed

  • 10mm or 12mm socket and ratchet (most models use 12mm, but always confirm with your 2026 owner's manual)
  • Oil catch pan or drain bucket
  • Funnel
  • Clean rag
  • Measuring jug or a quart bottle with markings
  • 28 fluid ounces (0.88 quart) of 10w40 Yamalube (or API SG or higher motorcycle oil)
  • Gloves (optional, but recommended)
  • Replacement drain bolt washer (optional, but can prevent future leaks)

Preparation

  • Start the bike and let it idle for 5–10 minutes. This helps the oil warm up and flow more freely, ensuring you drain as much old oil as possible. Always do this in a well-ventilated area and with the bike secure upright (TTR110 oil change guides).
  • Place your oil catch pan beneath the engine’s drain plug. The drain plug is located on the lower side of the engine case—refer to your Yamaha manual or frame markings for exact placement on the latest TTR110’s engine.

Draining the Old Oil

  • Remove the drain bolt using your socket and let the old oil fully drain into the pan. Be careful—the oil will be hot.
  • Remove the oil fill cap/dipstick on top of the engine—this allows oil to drain faster by preventing vacuum lock.
  • Inspect the drain bolt and washer. If the washer looks damaged or flattened, replace it with a new one to prevent leaks in the future.

Refilling with New Oil

  • Reinstall and gently tighten the drain bolt. Do not overtighten; aluminum threads can strip easily.
  • Place a clean funnel in the oil fill opening.
  • Carefully measure out 28 fluid ounces (0.88 qt) of 10w40 motorcycle oil. Yamahas are not particularly sensitive, but it is best practice to use Yamalube for consistent performance .
  • Pour the oil slowly to avoid overfilling. Tip: If your oil bottle has quart measurements, pour until only 4 fluid ounces remain in the bottle.

Checking Oil Level

  • With the bike level and upright (not on its side stand), insert the dipstick but do not thread it—just set it in and withdraw to check the oil level. If you see oil between the minimum and maximum marks, you’re good. If low, add small amounts and recheck.
  • Do not overfill—excess oil can cause blowby, leaks, or performance ruination. If you go over, carefully loosen the drain bolt to let small amounts out .
  • After starting the bike for 1–2 minutes, shut it off and let oil settle. Recheck the level, as oil will fill passages and the level may drop slightly.

Disposal and Cleanup

  • Wipe down any spilled oil with your clean rag.
  • Clean and store your tools.
  • Dispose of old oil safely—take it to a recycling center or an auto parts store with an oil collection service .

2026 Yamaha TTR110 Specific Call-Outs

  • For 2026, Yamaha continues with the proven no external oil filter design—there is no disposable oil filter; only the engine oil needs replacing. This makes the process especially quick and straightforward .
  • Torque spec for drain bolt: Always refer to your official Yamaha service manual for the exact drain plug torque. Generally, the TTR110's drain bolt requires about 14 ft-lbs (19 Nm), but always check your model-year specifics.
  • While the bodywork and plastics may have had minor stylistic updates, the oil fill and drain locations remain unchanged from prior years, making guides for TTR110 models from 2012–2025 directly applicable .
  • Be certain your engine is fully cooled before beginning if you're inexperienced—hot oil is a burn hazard.
