Tools and Supplies You’ll Need
- 12mm wrench or socket (for drain bolt removal)
- Drain pan (to catch old oil)
- Funnel
- Measuring container (optional, to measure oil volume)
- Rag or shop towels (for cleanup)
- Fresh oil – Recommended: 10W-40 motorcycle oil (Yamalube or Motul brands are preferred)
- Oil disposal container
- Gloves (optional, for cleanliness)
Best Practices and Specific Call-Outs for the 2008 Yamaha TTR110
- The TTR110 lacks an external oil filter—you’re just replacing the oil itself, making the process easier than most full-size bikes.
- This oil change method is consistent for TTR110 models produced from 2008 to present—Yamaha made no major changes to the oiling system or design in these years.
- Always use a high-quality 10W-40 motorcycle-rated oil for best engine protection and clutch compatibility.
- Oil capacity: The TTR110 requires 800cc (about 27 fl. oz) of oil. It’s recommended to start with 750cc, run the engine, and top off as needed to avoid overfilling.
- Check the oil level properly: After filling and running the engine, let the bike settle upright (not on the side stand) for accurate dipstick readings.
- Do not overfill: Too much oil can cause blowby, leaks, and engine performance issues. If you overfill, drain small amounts until the correct level is reached.
- Environmental responsibility: Always dispose of used oil at an authorized recycling facility or your local dealer.
Step-by-Step Instructions
-
Warm Up the Bike
- Start the bike and let it idle for 5–10 minutes. Warm oil drains faster and more completely.
-
Position the Bike and Gather Tools
- Shut off the engine.
- Place the bike on a stable, level surface using the center stand or an upright stand. Do not use the side stand, as it can cause inaccurate oil readings.
- Put your drain pan under the engine's drain bolt (located at the bottom of the crankcase).
-
Remove the Drain Bolt
- Using a 12mm wrench or socket, loosen (counterclockwise) and remove the drain bolt. Allow the oil to drain fully into the pan. Be careful; the oil might be hot.
-
Clean and Reinstall the Drain Bolt
- Inspect the drain plug and washer for damage. If the washer is worn out, replace it to prevent leaks.
- Wipe any debris from the area.
- Reinstall and hand-tighten the drain bolt, then snug it with your wrench. Do not overtighten to avoid stripping the threads.
-
Add Fresh Oil
- Remove the oil fill cap on the right side of the engine.
- Using a funnel, pour in about 750cc (just under 27 oz) of 10W-40 oil.
- Clean and reinstall the fill cap.
-
Check the Oil Level
- Start the engine and let it run for 1–2 minutes. Then shut it off and let the bike rest for 2–3 minutes to let the oil settle.
- Hold the bike upright and remove the oil dipstick (or check the sight glass, depending on the model). Wipe it off.
- Insert the dipstick without screwing it in, then remove to check the level. Add small amounts of oil as needed to reach the correct mark. Avoid overfilling.
-
Dispose of Used Oil Responsibly
- Pour the old oil into a sealed container and take it to your local auto parts store, authorized service center, or community hazardous waste recycling center.
-
Clean Up
- Wipe any spilled oil from the engine or frame. Clean your tools and your work area.
- Record your oil change date and hours/mileage in your maintenance log for reference.
Pro Tips for TTR110 Oil Changes
- Always use the correct oil type and grade for optimal clutch and engine performance.
- Do not “guess” at oil levels–measure and check with the dipstick or sight glass.
- Keep a spare drain plug washer on hand in case the original is damaged.
- If the oil looks milky, change it again soon and inspect for coolant leaks (milky oil can signal water in the crankcase).
- Take care not to cross-thread the oil drain bolt when reinstalling.
Final TTR110-Specific Reminders
- No need to replace an external oil filter—just drain and fill.
- Oil capacity is 800cc, but best practice is to start with 750cc, check, then top up to avoid accidental overfill.
- Do not ride with low or overfilled oil, as both can cause engine damage.
Regular oil changes are the simplest way to keep your Yamaha TTR110 running smooth for years to come. Follow this MotoSport.com guide every time, and your mini-moto is ready for the next adventure.
