Shop parts for your ride now.

Changing the oil in your 2023 Sherco 450 SEF FACTORY is a critical maintenance task that helps preserve engine longevity and performance. This step-by-step guide, proprietary to MotoSport.com, walks you through the process with specific callouts to ensure you perform the job correctly for this make, model, and year.

Tools and Supplies Needed:–

  • 8mm socket
  • 17mm socket
  • 4mm Allen key
  • Torque wrench (capable up to 20 Nm)
  • Oil drain pan
  • Rags or shop towels
  • 1.1 Liters of SAE 10W60 full synthetic motorcycle oil
  • New oil filter
  • Replacement crush washers (for drain bolts)
  • Gloves (optional for cleanliness)

Preparation:–

  • Warm up the engine for 2-3 minutes. Warm oil drains more easily and removes more contaminants.
  • Turn the motor off and ensure the bike is upright and secure—using a stand is recommended.
  • Work in a clean, well-ventilated area to prevent contamination of the engine internals

    .

Step-by-Step Oil Change Procedure:–

  1. Locate Drain Bolts:
    • The Sherco 450 SEF FACTORY uses two oil drain bolts on the engine underside. Identify both drain bolts to ensure complete oil removal. Each bolt has a crush washer that should be replaced every oil change

      .
  2. Remove the Oil Fill Cap:
    • Unscrew the oil fill cap located on the right side of the engine. This allows the oil to drain smoothly by preventing a vacuum

      .
  3. Drain the Oil:
    • Place your drain pan beneath both drain bolts.
    • Using the 17mm socket, remove the first drain bolt and let the oil flow out completely.
    • Remove the second drain bolt; some oil will drain from this side as well.
    • Inspect both drain bolts—one is magnetic. Clean any metal shavings from the magnetic tip, which helps you monitor engine wear

      .
  4. Remove and Replace the Oil Filter:
    • Find the oil filter cover on the right side of the engine block.
    • Use the 8mm socket to remove the cover’s bolts (usually three). Carefully pull off the cover.
    • Remove the used oil filter; some oil may drip, so keep your pan underneath.
    • Install a new oil filter as specified for your 2023 Sherco 450 SEF FACTORY. Always replace the filter at every oil change

      .
    • Reinstall the filter cover and torque the bolts to 8-10 Nm unless otherwise stated in your manual.
  5. Fit New Crush Washers and Reinstall Drain Bolts:
    • Install new crush washers on both drain bolts to prevent leaks.
    • Hand-tighten both bolts and then torque them to 15 Nm using a torque wrench as per the 2023 factory specification

      .
  6. Add New Oil:
    • Pour in 1.1 liters of SAE 10W60 engine oil. Check your manual for oil brand recommendations.
    • Screw the oil fill cap back on by hand.
  7. Check the Oil Level:
    • Start the engine and let it idle for 30 seconds, then turn it off.
    • Allow a minute for oil to settle, then use the sight glass to check the level; top off if necessary but do not overfill

      .
  8. Final Cleanup and Inspection:
    • Look for any leaks around the drain bolts and oil filter cover.
    • Wipe up all spills and dispose of used oil and oil filter responsibly at an oil recycling facility. Never dump oil in drains or on land

      .

Model-Specific Call-Outs for the 2023 Sherco 450 SEF FACTORY:–

  • Two drain bolts: Failure to remove both can result in incomplete oil removal.
  • Magnetic drain bolt: Clean it thoroughly; the presence of metal particles can help diagnose potential engine issues early

    .
  • Torque specs: Strictly adhere to factory torque values (15 Nm for drain bolts, check your manual for oil filter cover).
  • Oil type and quantity: Only use SAE 10W60 full synthetic oil–quantity is 1.1L for a complete change.
  • Environmental responsibility: Sherco emphasizes that all waste oil and filters must be recycled correctly

    .
