Special Notes for the 2024 GAS GAS EC 450F

  • Oil capacity: 1.2 liters (use manufacturer-recommended oil grade).
  • Applies to 2021-2024 MC 450F and EC/EX 450F engines—the process and items are nearly identical for these models.
  • Always warm the engine briefly before draining for thorough oil evacuation.
  • Inspect all drain plugs and the oil screen for debris or metal fragments, a key sign of internal wear.

Step-by-Step Oil Change Instructions

  1. Warm Up and Prep
    • Start the bike and let it idle for about 2-3 minutes. This helps the oil flow better and drain fully.
    • Turn off the engine and let it cool just enough to avoid burns.
    • Place the bike on a level stand to ensure accurate draining and refilling.
    • Have your drain pan ready beneath the engine.
  2. Remove Skid Plate (if equipped)
    • Use appropriate tools to remove the skid plate, exposing the drain plugs and oil filter cover.
  3. Clean Around Drain Plug & Filter
    • Clean the area around the oil drain plug and oil filter cover using a rag and contact cleaner to prevent dirt from contaminating the engine.
  4. Drain Engine Oil
    • Locate all oil drain points. Generally, there will be a main drain plug beneath the engine and one or two oil screen covers/plugs.
    • Using the correct wrench or Allen key, remove all drain plugs and allow oil to flow into the pan. Be patient and let it drain thoroughly.
    • Remove the oil fill cap to allow air flow for quicker drainage.
  5. Remove, Inspect, and Clean the Oil Screen(s)
    • Using snap ring pliers or the appropriate tool, extract the oil screen(s). Inspect and clean them by rinsing with fresh oil or contact cleaner, and allow to dry completely.
    • Check for metal shavings or contaminants; excessive debris may suggest internal wear and should be monitored.
  6. Replace the Oil Filter
    • Remove the oil filter cover using the specified bolts (refer to the owner's manual for exact location, typically right side).
    • Remove the old oil filter. Note the orientation for reinstalling the new one.
    • Lubricate the new filter's rubber seal with a bit of fresh oil and install it in the correct orientation.
    • Reinstall the oil filter cover and tighten bolts to manufacturer's torque specification.
  7. Install New Crush Washer and Refit Drain Plugs/Screens
    • Always use a new crush washer on the main drain bolt for proper sealing.
    • Thread in all drain bolts and screens carefully, then tighten to the specified torque to prevent stripping or overtightening.
  8. Add Fresh Oil
    • With a funnel, slowly pour in 1.2 liters of Motorex Cross Power 4T 10W/50 (or equivalent engine oil). Check your oil level with the sight glass or dipstick as directed in the manual.
    • Replace the oil fill cap securely.
  9. Start & Inspect
    • Start the engine and let it idle for a minute. Check for leaks around the drain plugs and filter cover.
    • Shut off the engine, wait for a couple of minutes, then re-check the oil level and top off if needed.
  10. Reinstall Skid Plate and Clean Up
    • Once satisfied, reinstall the skid plate and wipe down any spilled oil.

Model-Specific Callouts for the 2024 GAS GAS EC 450F

  • The EC 450F shares engine and chassis basics with KTM and Husqvarna 450/501 models, so procedures are similar. Always use components rated for the 2024 model year for best results and longevity.
  • Verify all gaskets and O-rings are in good condition each service cycle, and replace worn parts as needed to prevent leaks.
  • Tighten all bolts to the correct specification–overtightening the drain plug can damage the aluminum cases.
  • If you notice metallic debris in the oil screens, consult your dealer or mechanic to inspect for possible internal engine wear.

Final Tips

  • Dispose of used oil and the old filter responsibly at a suitable collection facility.
  • Keep a maintenance log to track service intervals and note any abnormalities.
  • Refer to your owner's manual for official torque specs and additional guidance surrounding the lubrication system.
