  • Torque wrench
  • Oil drain pan
  • Gloves & rags

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Start your FX450 and let it idle for 2–3 minutes. This helps the old oil drain completely and suspends contaminants for removal.
  2. Prepare Your Workspace
    • Turn off the bike and place it upright on a stand or secure it to prevent tipping.
    • Remove the skid plate if equipped, to access the drain plug easily .
  3. Drain the Old Oil
    • Place the drain pan under the engine’s drain plug (usually found underneath the crankcase).
    • Use the correct socket to carefully remove the drain bolt. Allow the oil to drain fully—wait several minutes for thorough drainage.
    • Inspect the drain plug and washer for excessive metal debris or damage. Replace the crush washer if needed.
  4. Remove and Replace the Oil Filter
    • Locate the oil filter cover (right side of engine; Part No. 75038041200) and remove it with a socket or Allen wrench .
    • Carefully extract the old oil filter (Part No. 77038005044). Watch for drips of old oil here.
    • Install a new O-ring (Part No. 0770039026) on the filter cap for proper sealing .
    • Lightly oil the new filter with fresh engine oil (to prime it), then push it securely into place .
    • Reinstall the oil filter cap and torque it to manufacturer’s specifications.
  5. Inspect and Clean Oil Screens (if equipped)
    • The FX450 may have mesh screens in the system—remove, inspect, and clean these if present (see manual for exact location, often near the drain plug or side cover) .
  6. Reinstall Drain Plug
    • Wipe around the drain hole with a clean rag.
    • Re-install the drain plug and washer; torque to spec.
  7. Fill With Fresh Oil
    • Remove the oil fill cap.
    • Using a funnel, pour in 1.06 quarts (1,000 ml) of 10W-50 fully synthetic motorcycle oil, or as specified for your climate and riding style .
    • Replace the oil fill cap.
  8. Check Oil Level
    • Start the engine and let it run for 2–3 minutes.
    • Shut the engine off and allow it to sit for 1–2 minutes so the oil can settle.
    • Inspect the oil sight glass (if present) or dipstick. Oil should be halfway up to three-quarters in the sight window . Adjust by adding oil in small amounts if low.
  9. Final Steps
    • Check for leaks around the drain bolt and filter cap with the engine running.
    • Reinstall the skid plate (if removed).
    • Dispose of old oil and filter responsibly at a recycling center.

Model-Specific Callouts for the 2010 Husaberg FX450

  • Use the correct oil filter and O-ring ONLY from Husaberg/KTM suppliers (Part Nos. 77038005044 and 0770039026, respectively) .
  • Double-check oil capacity – FX450 uses 1.06 quarts (1,000 ml) . Overfilling or underfilling can affect engine performance.
  • Inspect for mesh screens – clean them each oil change to protect the oil pump; their presence is confirmed in the FX series .
  • Service interval – For off-road or racing use, change oil and filter as frequently as every 10–15 hours of riding.
  • Oil sight glass makes level checking much easier; ensure it reads between half and three-quarters full after starting and settling .

Expert Tips

  • Always use a high-quality, full synthetic oil for the best protection, as high-performance KTM/Husaberg motors run hot and need robust lubrication .
  • If you notice shiny flakes in old oil or unusual noises after an oil change, investigate before riding further.
  • Torque all bolts to specification—over-tightening can strip cases, while under-tightening risks leaks.
  • The first oil change after engine break-in is critical—follow the shorter, factory-recommended interval initially.

Performing this oil change yourself gives you the confidence of knowing your FX450’s engine is protected during every ride. For OEM and performance oil change kits, shop MotoSport.com for everything you need to keep your 2010 Husaberg FX450 running strong.
