The 2020 Sherco 250 SEF FACTORY is a high-performance enduro motorcycle, and regular oil changes are crucial for maintaining optimal engine function and reliability. This guide from MotoSport.com will walk you step-by-step through the oil change process, highlight required tools and materials, and provide specific tips for this make, model, and year.

Tools and Materials Needed

  • Socket set (for drain plugs and oil filter cap)
  • Oil drain pan
  • Torque wrench (for precise torque specs)
  • New oil filter (replace every change)
  • New O-ring for oil filter cap (recommended for each change)
  • New crush washers for drain plugs
  • Engine oil: SAE 10W60, 0.9L capacity
  • Funnel
  • Clean rags
  • Gloves

Step-by-Step Oil Change Procedure

  • Start the Engine: Run your bike for 2-3 minutes. This helps warm the oil, allowing it to flow out more freely when draining.
  • Secure the Bike: Place the bike on a stable stand or level surface to prevent tipping.
  • Remove Skid Plate (if installed): If your Sherco is equipped with an engine guard, remove it for easy access to the drain plugs and filter.
  • Position Oil Pan: Place your oil drain pan under the engine's bottom to catch old oil.
  • Remove Drain Plugs: There are two drain plugs on the 250 SEF FACTORY:
    • Primary drain plug (M19)
    • Magnetic drain plug (M12)
    Use the socket set to carefully loosen and remove each plug. Allow all oil to drain. Inspect for metal debris, especially on the magnetic plug.
  • Remove Pre-Filter Screen: Unscrew and pull out the pre-filter (metal mesh screen). Clean with solvent and allow to dry before reinstalling.
  • Remove Oil Filter Cap: Locate the oil filter on the engine's right side. Remove the oil filter cap (M45), preferably using a new O-ring. Pull out the old filter and dispose of it as per local regulations.
    • Always install a new oil filter for every oil change.
  • Install New Filter and Reassemble: Insert a new oil filter, ensuring correct orientation. Replace the cap using a new O-ring and tighten to the specified torque (–15 Nm–).
  • Reinstall Pre-Filter and Drain Plugs:
    • Install pre-filter and both drain plugs with fresh crush washers.
    • Torque Specs:
    • Primary drain plug (M19): 22 Nm
    • Magnetic drain plug (M12): 15 Nm
  • Refill Engine Oil:
    • Remove the engine oil filler cap (top of the engine, visible on the right side).
    • Add 0.9 liters SAE 10W60 4-stroke oil. A funnel helps prevent spills.
  • Check Oil Level:
    • Check the oil level using the sight glass on the engine case with the bike level and upright.
    • Add oil in small amounts if necessary. Do not overfill.
  • Reinstall Skid Plate: If previously removed, reinstall your engine guard or skid plate.
  • Start and Inspect: After everything is secure, start the motorcycle. Allow it to idle for a few minutes, then shut it off and check for leaks at the drain plugs and filter. Re-check the oil level and top off if necessary.
  • Dispose of Used Oil and Filters Properly: Take all waste oil, filters, and used rags to an appropriate recycling center. Never dispose of oil in household trash, drains, or on the ground.

Model-Specific Tips and Call-Outs

  • Duo Drain Plugs: The 2020 Sherco 250 SEF FACTORY has two drain plugs. Both must be removed for a complete oil change.
  • Oil Filter Orientation: Be sure the new oil filter is installed in the correct direction—refer to a service manual diagram if unsure. An incorrect install can lead to poor lubrication.
  • Pre-Filter Maintenance: Cleaning the mesh pre-filter is crucial; it traps large debris before oil reaches the main filter.
  • O-Rings and Crush Washers: Always use new O-rings and crush washers to prevent leaks and ensure proper sealing.
  • Sight Glass Caution: The sight glass offers a clear way to check oil level, but make sure the bike is truly upright and level for an accurate reading.
  • Oil Choice: Use a high-quality synthetic SAE 10W60 oil as recommended for strong engine protection, especially under hard riding conditions.
  • Recommended Change Interval: While the manual may suggest up to 100 hours, aggressive or race use should cut that interval in half (every 40–50 hours), and always after mud, water crossings, or hard competition use.

Final Thoughts

  • Changing the oil on your 2020 Sherco 250 SEF FACTORY is a straightforward task with the proper tools, and is one of the best ways to extend engine life.
  • Following the precise torque specs and part replacements will help avoid leaks, stripped bolts, or damage to your engine.
  • If ever in doubt, always consult your official Sherco workshop manual or reach out to MotoSport.com experts for model-specific support.
