Tools & Supplies Needed

  • 8mm socket and 17mm socket
  • 4mm Allen wrench
  • Oil drain pan
  • Funnel
  • Shop towels or rags
  • New oil filter (replace every change)
  • New crush washers for drain bolts
  • Engine oil (SAE 10w50, 1.1L recommended volume)
  • Torque wrench
  • Parts cleaner (optional, for cleaning magnetic drain plug and area around oil fill)

Important Model-Specific Call–Outs

  • This bike uses two drain bolts on the bottom—both must be removed to drain oil completely.
  • Always use a new oil filter and replace both drain plug crush washers with each change.
  • Tighten the oil filter cover and drain bolts to the right specifications to avoid damaging the threads or causing leaks.
  • There is a magnetic drain plug—clean thoroughly to remove any metal particles.
  • Check the oil level using the inspection window after refilling.

Step-by-Step Oil Change Process

  1. Warm Up the Engine
    • Start the bike and let it idle for 2-3 minutes. This helps the oil flow out fully when drained.
    • Shut off the engine and secure the bike on a stable stand or level surface.
  2. Remove Skid Plate (If Installed)
    • If your bike is equipped with a skid plate, remove it to access the drain bolts with an 8mm or 10mm socket.
  3. Drain the Oil
    • Position the oil drain pan under the engine.
    • Locate both oil drain bolts on the underside and use a 17mm socket to remove them. Be careful as the oil may be hot.
    • Remove the oil fill cap on the right side cover to help oil drain faster.
    • Inspect and clean the magnetic drain plug, removing all debris.
    • Replace both crush washers with new ones for optimal sealing.
  4. Replace the Oil Filter
    • Use a 4mm Allen wrench to remove the oil filter cover.
    • Remove the old oil filter and O-ring.
    • Wipe off any old oil and debris from the filter cavity.
    • Install the new oil filter, ensuring correct orientation as shown in the workshop or owner‘s manual.
    • Fit a new O-ring if required, then reinstall the oil filter cover. Tighten to 8-10 Nm–or hand-tight, then snug.
  5. Refit the Drain Plugs
    • Install both drain bolts with new crush washers.
    • Tighten each to 15 Nm using your torque wrench.
  6. Add New Oil
    • Insert a funnel into the oil fill hole.
    • Pour in 1.1 liters of SAE 10w50 4T motorcycle oil as recommended for this model.
    • Reinstall the oil fill cap with a new O-ring if present, torque to 20 Nm.
  7. Check the Oil Level
    • Start the bike and let it idle for about a minute to circulate the new oil. Shut it off, wait about two minutes for oil to settle.
    • Check the oil level via the inspection window on the engine case. The oil should be between the level lines. Top off if necessary.
  8. Inspect for Leaks and Finalize
    • Double-check all bolts and the oil filter cover for leaks.
    • Dispose of oil and old filter at a certified recycling center—never pour them into drains or on the ground.
    • Reinstall the skid plate if removed.

Additional Tips for 2022 Sherco 450 SEF FACTORY Owners

  • Use only properly rated motorcycle oil as specified by Sherco for optimal clutch performance and engine lifespan.
  • The magnetic drain plug is a critical maintenance item—always inspect for metal debris that could signal internal engine wear.
  • Change the oil and filter together every 10-15 hours of riding, or sooner if you ride in extremely dusty or muddy conditions.
  • Over-tightening any fastener on the engine can damage soft aluminum parts. Use a calibrated torque wrench.

Conclusion

Changing the oil on your 2022 Sherco 450 SEF FACTORY is a straightforward, essential maintenance step that protects your engine and maximizes performance. Following the above steps and using the correct tools and parts ensures a smooth process every time.
