Shop parts for a 2014 Husqvarna TE125 Dirt Bike.

Regularly changing the oil in your 2014 Husqvarna TE125 is crucial for maintaining optimal engine and gearbox performance. This guide is proprietary to MotoSport.com and crafted specifically for the 2014 model, highlighting any unique aspects an owner should know about this dirt bike.

Tools and Materials Needed

  • Socket wrench (with correct size for oil drain bolt–usually 13mm or 14mm for Husqvarna 125s)
  • Drain pan (to catch old oil)
  • Rag or shop towels (for cleanup)
  • Disposable gloves (to keep hands clean)
  • Measuring cup (capable of measuring 650ml accurately)
  • Funnel (for clean pouring)
  • Replacement crush washer (recommended to replace each oil change)
  • Gearbox/Transmission oil (650ml, as specified by Husqvarna; refer to user manual for oil weight recommendation: typically Motorex Top Speed 4T 15W-50, but confirm for your temperature and riding style)
  • Screwdriver (if necessary for removing skid plate or side covers)

Before You Begin: Model-Specific Call-Outs

  • The 2014 Husqvarna TE125 uses a separate gearbox oil; engine lubrication is provided by the fuel-oil premix as it is a 2-stroke dirt bike.
  • The correct gearbox oil capacity is 650ml for the TE125. Overfilling or underfilling can cause clutch problems or transmission wear.
  • Oil should be changed after break-in, and then at regular intervals specified in your owner—s manual (typically every 5–10 hours of use or after muddy/wet rides).

Step-by-Step Oil Change Instructions

  • 1. Warm Up the Engine
    • Start the bike and let it idle for about 3–5 minutes. This helps the oil flow more easily and carries contaminants away from the gearbox surfaces.
    • Shut off the engine and allow the bike to cool for a minute until it's comfortable to touch—never drain oil when engine parts are dangerously hot.
  • 2. Set Up Your Work Area
    • Place your dirt bike on a stand so it's vertical and stable.
    • Position the drain pan directly beneath the oil drain bolt located at the lowest point of the gearbox case (check your manual or owner—s manual diagram if you're unsure).
  • 3. Remove the Oil Fill Cap
    • Locate the fill cap (usually on the right side, towards the top of the clutch cover) and remove it. This allows air to enter, helping oil drain smoothly.
  • 4. Remove the Drain Bolt
    • With a socket wrench, loosen and remove the oil drain bolt at the bottom of the gearbox case. Be careful—the oil may drain quickly and can be hot.
    • Allow the oil to fully drain out. Tilt the bike gently side to side to get the last drops out.
    • Inspect and replace the crush washer on the drain bolt to prevent leaks.
  • 5. Reinstall the Drain Bolt
    • Once the oil has fully drained, reinstall the drain bolt and tighten securely (do not overtighten; typically around 10–15 Nm—check your manual for the exact spec).
  • 6. Add Fresh Gearbox Oil
    • Use a funnel and pour in exactly 650ml of the specified oil for your bike.
    • Pace the pour and check for any spills. The oil must be added while the engine is cold for accurate measurement and to prevent burns.
    • Double-check the oil level, if your bike has a sight glass or check screw (some models do). Otherwise, trust your measured addition.
  • 7. Replace the Fill Cap
    • Screw the oil fill cap back on securely. Wipe away any oil drips.
  • 8. Dispose of Old Oil Properly
    • Pour the old oil into a sealed container and take it to an approved oil recycling location. Never dispose of oil in drains or on the ground.

Key Additional Tips for the 2014 TE125

  • Using the correct oil type can greatly affect clutch feel and gearbox durability. Double-check weights and recommendations in your owner—s manual or with MotoSport's product specialists.
  • Always replace the crush washer during each oil change to avoid leaks.
  • Inspect the removed oil for metal shavings or milky coloration, which could indicate internal wear or water contamination.
  • Write down the date and engine hours after each change to stay on schedule for the next interval.
  • If the drain bolt is stripped or the threads are damaged, replace the bolt immediately.
  • Run the engine briefly after the oil change and inspect for leaks around the drain and fill bolt areas.

Common Mistakes to Avoid

  • Not warming up the engine before draining (can leave debris in gearbox).
  • Forgetting to reinstall or improperly tightening the drain bolt—always hand tighten first, then torque to spec.
  • Overfilling or underfilling the oil—650ml is the precise amount for the 2014 TE125; never estimate by eye.
  • Using incorrect oil type or viscosity—always follow Husqvarna's recommendations.
