Shop parts for a 2007 Yamaha TTR50 Dirt Bike.

Regular oil changes are essential to keep your 2007 Yamaha TTR50 running reliably and smoothly. This dirt bike is known for its simplicity and durability, but like all motorcycles, it requires basic attention to ensure a long life. Our guide walks you through every step of the process, highlighting key model-specific tips for your Yamaha TTR50. All steps and recommendations are based on best practices and Yamaha's maintenance guidelines.

Tools & Supplies Needed

  • 10W-40 motorcycle oil (preferably Yamalube or high-quality 4-stroke oil)
  • Measuring cup or graduated container to ensure you use the correct amount (800ml total)
  • 17mm socket and ratchet for the drain bolt
  • Oil drain pan
  • Funnel (to prevent spills)
  • Shop rags or paper towels for cleaning up spilled oil
  • Gloves (recommended for cleanliness)

Special Notes for the 2007 Yamaha TTR50

  • Fill capacity is 800ml. The engine takes about 800 milliliters of oil. Some riders prefer adding about 750ml first, then topping off as needed after checking the dipstick for accuracy. Overfilling can cause oil to leak into the air filter, so being precise is important

    .
  • Always check oil level with the bike on a level surface for an accurate reading

    .
  • No oil filter to change or clean on this bike model — just the oil itself.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your TTR50 and let it idle for 2–3 minutes. This warms up the oil, making it thinner and easier to drain

      .
    • Turn off the engine and let it sit for a few moments to avoid burns.
  2. Position the Bike
    • Place the bike on a level surface with the kickstand up to ensure accurate oil drainage and filling

      .
  3. Drain the Old Oil
    • Locate the drain bolt underneath the engine (17mm bolt).
    • Place the oil drain pan under the bolt.
    • Carefully loosen and remove the drain bolt, allowing the oil to drain completely.
    • Be careful not to lose the drain bolt or its washer.
    • Allow several minutes for all oil to flow out

      .
  4. Replace the Drain Bolt
    • Once the oil has fully drained, reinstall the drain bolt and gently tighten with the 17mm socket. Do not overtighten. Over-torquing can strip the threads in the crankcase

      .
  5. Fill with New Oil
    • Clean around the dipstick and remove it from the fill port.
    • Use a funnel and pour in about 750ml of 10W-40 oil to start

      .
    • Wipe off and reinsert the dipstick (without screwing it in yet) to check the level. Add more oil in small increments until you reach the correct mark. Do not exceed 800ml total

      .
    • If you overfill, carefully drain a little oil out by loosening (not removing) the drain bolt

      .
  6. Check the Oil Level
    • To check, hold the bike upright and insert the dipstick but do not screw it in. Remove and read the level.
    • Aim for oil to register between the minimum and maximum marks. If needed, add or subtract oil as above

      .
    • Once satisfied, securely reinstall the dipstick.
  7. Start and Inspect
    • Start the engine and let it idle for about a minute. Shut it off and let the oil settle for 2–3 minutes.
    • Recheck the oil level and adjust if necessary. Inspect under the bike to ensure no leaks at the drain bolt.

Maintenance Tips & Model-Specific Reminders

  • Always use motorcycle-specific oil; automotive oil does not contain adequate clutch protection additives.
  • Inspect the drain bolt O-ring for any cracks or deformations and replace if worn to prevent leaks

    .
  • Overfilling can force oil into the air filter, causing a mess and poor running. Always check and add oil carefully

    .
  • Change oil every 10–15 hours of riding, or every few months if not ridden regularly

    .
  • Changing your oil is a great time to familiarize yourself with other maintenance points like spark plugs or chain tension.

By following these steps, your 2007 Yamaha TTR50 will stay in peak condition, delivering many more hours of fun and reliable performance. Regular oil changes are quick, easy, and essential — and with these MotoSport.com tips, you’re always in control of your ride.
