Shop parts for a 2023 KTM 450SMR Dirt Bike.

Changing the oil in your 2023 KTM 450SMR is essential for maintaining the engine's performance and ensuring the longevity of your investment. Regular oil changes remove contaminants, reduce engine wear, and keep your motorcycle running smoothly, especially under the intense conditions the 450SMR is built for. This proprietary guide, brought to you by MotoSport.com, outlines all the tools you'll need, step-by-step instructions, and specific tips unique to the 2023 KTM 450SMR.

Tools & Supplies Needed

  • Socket wrench with 8mm and 13mm sockets
  • Pliers (for stubborn bolts or oil screen)
  • Drain pan
  • Rags (to catch spills and clean up)
  • New oil filter
  • OEM-spec engine oil (1.2 liters Cross Power 10W50 or 10W60 recommended)
  • Replacement crush washer (recommended but optional if existing one is in good condition)
  • Torque wrench
  • Funnel
  • Rubber gloves (for cleaner hands)

Prepare for the Oil Change

  • Make sure the engine is warm, not hot – run it for a few minutes. Warm oil drains more efficiently and takes more contaminants out.
  • Park the bike on a stand or upright, stable surface.
  • Remove any skid plate or lower guards to access the drain plugs.

Step-by-Step Instructions

  1. Drain the Old Oil
    • Place the drain pan under the engine, aligned with both drain bolts.
    • Using a 13mm socket, remove both engine oil drain bolts. Some oil may spill onto the frame – this is normal for this model and is difficult to avoid.
    • Allow all oil to fully drain – tilting the bike slightly may help get the last bit out.
  2. Remove & Clean the Oil Screen
    • Use pliers, if needed, to carefully remove the oil screen.
    • Inspect the screen for debris and give it a thorough cleaning before reinstalling.
  3. Remove & Replace the Oil Filter
    • Locate the oil filter cover and use the correct socket (usually 8mm) to remove it.
    • Pull out the old filter and discard it.
    • Lubricate the O-ring on the new filter with fresh oil and insert it, ensuring correct orientation.
    • Reinstall the filter cover and torque it to factory specifications (usually 8-10 Nm, but check your manual for exact value).
  4. Reinstall and Torque the Drain Plugs
    • Clean threads and inspect or replace the crush washers if necessary to avoid leaks.
    • Reinstall the drain bolts by hand first, then torque to specification: 20 Nm for drain bolts (confirm in your owner's manual).
    • Reinstall the cleaned oil screen and torque its bolt.
  5. Add Fresh Oil
    • Using a funnel, pour in 1.2 liters of KTM-recommended 10W50 or 10W60 oil (Motorex Cross Power is the most common KTM recommendation).
    • Wipe any oil spills and reinstall the oil fill cap securely.
  6. Start & Check
    • With the bike vertical, start the engine and let it idle for 2 minutes. Shut it off and wait 1-2 minutes for oil to settle.
    • Check the oil level sight glass on the right side of the engine. The level should be between the marks – top up if needed in small increments.
  7. Reinstall Skid Plate & Final Check
    • Reattach the skid plate or any covers you previously removed.
    • Wipe down the engine, inspect for leaks, and dispose of oil responsibly at your local collection center.

2023 KTM 450SMR-Specific Callouts

  • Oil Change Interval: KTM recommends changing oil every 6,000 km (or about 4,000 miles), but more frequent changes (every 10-15 hours or after hard track riding) are common and wise for racing or heavy off-road usage.
  • Oil Capacity: 1.2 liters with filter; double-check with the manual if adding or draining large amounts.
  • Drain Plugs: Two drain bolts (13mm) and a reusable oil screen; both must be removed for complete drainage.
  • OEM Oil Spec: Use only high-quality, fully-synthetic oil, such as Motorex Cross Power 10W50 or 10W60, to maintain warranty and maximum protection.
  • Tools: 13mm and 8mm sockets, torque wrench, and pliers are essential for the 2023 model.
  • Engine Placement: Oil can drip onto the frame during draining; be prepared with rags for easier cleanup.
  • Filter Installation: Always lube the oil filter O-ring with clean oil for proper sealing. Never over-tighten drain bolts or filter cover; follow torque specs closely to avoid engine case damage.

Final Tips for Success

  • If you ride in dusty or muddy environments, inspect and change oil more often to keep your engine protected.
  • Inspect the removed oil for metal shavings or debris – this can be a sign of early engine wear or damage.
  • Always use the recommended oil filter and gasket for your bike's year and model – using non-OEM parts can cause leaks or pressure issues.
  • Dispose of oil and filters responsibly – never pour down the drain or on the ground.
