Regular oil changes are essential to keep your 2019 Sherco 250 SEF FACTORY running at peak performance. This comprehensive, model-specific guide from MotoSport.com covers every detail: required tools, step-by-step instructions, and manufacturer-specific tips to ensure a successful oil change.

Tools and Materials Needed

  • Socket set (including 8mm, 17mm, and 19mm sockets)
  • 4mm Allen wrench
  • Oil drain pan
  • Funnel
  • New oil filter (replace with every oil change)
  • New drain plug gaskets (crush washers)
  • New O-rings for filter/caps (optional but strongly recommended)
  • Torque wrench
  • Clean rags
  • High-quality 4-stroke motorcycle oil (SAE 10W60, 0.9L required)
  • Nitrile gloves (optional, for cleanliness)

Preparation

  • Warm up the engine. Run your bike for 2-3 minutes so the oil flows out smoothly and contaminants suspend in the oil.
  • Stabilize the bike. Place your bike upright on a stand; a level workspace is crucial for accurate oil level checks.

Step-By-Step Oil Change Instructions

  1. Remove the skid plate (if equipped):
    • This step allows access to the drain plugs and prevents mess.
  2. Place the oil drain pan below the engine.
    • Be sure it is large enough to catch at least 1 liter of oil.
  3. Remove both drain plugs.
    • Your 2019 Sherco 250 SEF FACTORY uses two oil drain plugs on the bottom of the crankcase: one is a standard drain and the other is a magnetic plug. Use the 17mm, 19mm sockets, and the 8mm socket as needed, per the plug size. Both have crush washers/gaskets that should be replaced with every oil change.
    • Let all of the old oil drain fully into the pan.
  4. Remove the pre-filter.
    • Located near one of the drain plugs, the pre-filter traps larger particles. Inspect and clean or replace as necessary.
  5. Remove the oil filter cap and oil filter.
    • Use the appropriate Allen or socket tool to remove the oil filter cap.
    • Pull out the old oil filter (note its orientation for reassembly). Replace the O-ring on the cap if it shows any wear or damage.
  6. Install a new oil filter.
    • Install the new filter in the correct direction shown in documentation. The filter should fit snugly.
    • Reinstall the oil filter cap with a new O-ring if needed, torquing to 15Nm.
  7. Reinstall the pre-filter and drain plugs.
    • Install the pre-filter and both drain plugs using new crush washers. Torque the magnetic plug (M12) and filter cap (M45) to 15Nm, and the main drain plug (M19) to 22Nm for a secure, leak-free seal.
  8. Add new engine oil.
    • Remove the engine oil filler cap.
    • Add 0.9L of SAE 10W60 high-quality 4-stroke motorcycle oil using a funnel for accuracy and cleanliness. Do not overfill.
  9. Check the oil level.
    • Allow the oil to settle for a minute. Check through the sight glass. Add oil if necessary to reach the proper level–never overfill.
  10. Reinstall the engine guard/skid plate.
  11. Start the engine and check for leaks.
    • Let the engine idle for a few minutes, then inspect around drain plugs and filter area for any sign of leaks. Shut off the engine and recheck the oil level, topping up as needed.
  12. Dispose of old oil and filter responsibly.
    • Take used oil and the filter to a local recycling facility. Never dispose of them in the trash or pour oil down drains or into the ground.

Sherco 250 SEF FACTORY Model-Specific Call-Outs

  • Two drain plugs: Both must be removed to ensure all used oil and particles are drained. Always use new crush washers to prevent leaks and torque to specified settings for your model.
  • Oil capacity: 0.9 liters is required for the 2019 model. DO NOT overfill–use the sight glass to confirm the level.
  • Oil type: Use only SAE 10W60 fully synthetic motorcycle oil for optimal engine life and performance.
  • Replace the oil filter at every oil change to maintain filtration efficiency.
  • When reinstalling, always observe proper torque values: magnetic plug and oil filter cap at 15Nm, main drain plug at 22Nm. Over-tightening may damage threads or the case. Under-tightening risks leaks.
  • Inspect the pre-filter and cleanness of oil for any abnormal debris—a sign of internal engine wear.
  • Some models use a magnetic drain plug; clean debris from the magnet before reinstalling.

Expert MotoSport.com Tips

  • Use gloves to protect your hands from hot oil and chemicals.
  • Clean up spills quickly to prevent slipping and environmental contamination.
  • Track oil change intervals in your maintenance log—Sherco recommends 25-30 hours for routine changes, but inspect your oil and adjust if you ride hard or in harsh environments.
  • If you notice metal shavings or large debris on the magnetic plug or in your oil, consult a MotoSport.com tech or Sherco dealer immediately.
