This guide covers the tools required, a detailed procedure, and crucial tips specific to the 350XCF platform.

Tools & Supplies Needed

  • 10mm socket (for oil filter cover bolts)
  • 13mm socket (for oil drain bolt and oil strainer bolt)
  • Socket wrench
  • Needle-nose pliers (for removing the oil strainer)
  • Drain pan
  • Funnel
  • Oil measuring cup
  • Torque wrench (to avoid over-tightening bolts)
  • Contact cleaner or brake cleaner
  • Shop towels or rags
  • Gloves (recommended)
  • Replacement engine oil – 1.0 liter Motorex Cross Power 4T 10W/50 full synthetic or equivalent
  • Replacement oil filter (OEM recommended)
  • New drain bolt crush washer

Preparation Steps

  • Warm up the bike for a couple of minutes. This helps the oil flow and suspends contaminants for removal. Shut off the engine and let it cool enough to avoid burns.
  • Set your bike upright using a stand in a clean, well-ventilated area.

Oil Change Procedure

  1. Remove Skid Plate (if equipped)
    • This step makes accessing the drain plug and oil strainer easier and minimizes mess. Use the appropriate tools if a skid plate is installed.
  2. Remove the Main Oil Drain Bolt
    • Place your drain pan beneath the engine. Using a 13mm socket, loosen and remove the main oil drain bolt located on the bottom of the case. Make sure to retrieve the crush washer with the bolt.
    • Allow the oil to drain completely.
  3. Remove and Clean the Oil Strainer
    • Using the 13mm socket, remove the oil strainer bolt.
    • Use needle-nose pliers to gently pull out the oil strainer.
    • Clean the strainer thoroughly with contact cleaner and inspect for debris or metal fragments, which might indicate internal engine wear.
  4. Remove the Oil Filter
    • Locate the oil filter cover (typically secured with 10mm bolts) and remove the bolts.
    • Carefully pull off the cover and remove the old oil filter.
    • Inspect the oil for excessive metal particles and clean the filter cavity with a rag.
  5. Install the New Oil Filter
    • Lubricate the new filter's O-ring with fresh oil, then seat the new filter in place.
    • Reinstall the oil filter cover, tightening the bolts to the manufacturer's specifications.
  6. Reinstall Oil Strainer & Drain Bolt
    • Reinsert the cleaned oil strainer and torque the bolt to spec.
    • Install a new crush washer on the main drain bolt, then reinstall and torque to specification (usually between 10-15 Nm; always confirm in your service manual).
  7. Add Fresh Oil
    • Through the oil fill port, pour in 1.0 liter of Motorex Cross Power 4T 10W/50 or your chosen fully synthetic oil, using a funnel and measuring cup for accuracy.
  8. Prime and Check Oil Flow
    • Some prefer to fill the new filter with a bit of oil before installation. Alternatively, after refilling, hold the kill switch and briefly crank the engine to circulate oil before starting.
    • Start the engine and let it idle for a minute. Check for leaks at the drain bolt, strainer, and oil filter cover.
    • Shut off the engine, let it sit for a moment, and check the oil level via the sight glass or dipstick. Add oil if necessary.
  9. Clean Up
    • Clean up any oil residue with contact cleaner and shop towels.
    • Dispose of old oil and filter responsibly per local regulations.

2025 KTM 350XCF FACTORY EDITION: Special Notes & Call-Outs

  • Oil Capacity: 1.0 liter for a full change with filter (confirm in your owner’s manual).
  • Torque Specs: Always follow KTM’s updated specifications; overtightening can crack cases or damage threads. If in doubt, use a torque wrench set to 10–15 Nm for the drain and strainer bolts.
  • Crush Washer: Replace the drain plug crush washer at every oil change to prevent leaks.
  • Oil Change Frequency: KTM recommends changing oil every 10–15 hours of riding (more frequently for race conditions).
  • Filter Orientation: Pay attention to the orientation of the oil filter when installing; it only fits one way and reversing it can cause oil starvation.
  • Debris and Metal Fragments: Carefully inspect both oil and strainer for any alarming debris—it may signal internal wear.
  • Service Intervals: For new bikes, complete the first oil change after initial break-in (about 1–3 hours) to remove early wear particles.

Routine oil changes are a straightforward but vital aspect of maintaining your 2025 KTM 350XCF FACTORY EDITION.
