Tools and Supplies Needed
- Metric wrench set (at least up to 13mm; the drain bolt requires a wrench as sockets won't fit easily on the 2020 model)
- Oil drain pan
- Needle-nose pliers (for removing the oil screen)
- Cleaning rags or shop towels
- Fresh engine oil (KTM recommends full synthetic 10W-50; check your owner's manual for capacity and specifications)
- New oil filter (OEM part number 77338005100, compatible aftermarket options include K&N and HiFlo)
- Oil filter cover O-ring (KTM #07703305178)
- Replacement drain plug crush washer (recommended for every change)
- Funnel (for clean, spill-free pouring)
- Torque wrench
- Gloves
Changing the Oil: Step-by-Step
-
Warm Up the Engine
- Start the engine and let it idle until it reaches operating temperature (check the radiator cap for warmth, but never open it while hot).
- Warming up helps the oil drain thoroughly by thinning it out.
-
Put the Bike on a Stand
- Stabilize the bike upright on a motorcycle stand for safe, clean draining.
-
Remove the Skid Plate (if equipped)
- If your KTM 250SXF has an aftermarket skid plate, remove it for full access to the drain bolt.
-
Locate and Remove the Drain Plug
- The drain bolt is behind a frame tube on the bottom left side of the engine. On the 2020 model, a wrench is needed since a socket won't fit well due to clearance limits.
- Place your oil drain pan directly below and carefully loosen the drain bolt.
- Let the oil drain completely.
-
Model-Specific Tip:
- The drain bolt on the KTM 250SXF has a magnet tip to capture metallic debris. Inspect and fully clean debris off the magnet before reinstalling.
- Replace the crush washer before reinstalling the drain bolt to prevent leaks.
-
Remove and Clean the Oil Screen
- The oil screen is located close to the drain plug. Use needle-nose pliers to gently wiggle it free.
- Inspect for debris and thoroughly clean it.
- Reinstall the oil screen, ensuring it is seated snugly.
-
Remove and Replace the Oil Filter
- Remove the oil filter cover with the correct wrench; note the O-ring—replace it if worn or damaged.
- Take out the old filter and install the new one (OEM 77338005100 or comparable option).
- Lubricate the O-ring with fresh oil before reinstalling the cover.
- Torque the cover bolts to manufacturer specs (see owner's manual).
-
Reinstall the Drain Plug
- Wipe down all surfaces, then reinstall the drain plug with a new crush washer.
- Torque to spec: Don't overtighten. Exact torque is in your owner's manual. Over-torquing can crack the engine case.
-
Add Fresh Oil
- Remove the oil fill cap located on top of the engine.
- Using a funnel, pour in the correct amount of full synthetic 10W-50 oil (check manual, typically just under 1 liter for the 250SXF).
-
Run the Engine and Top Off
- With everything reinstalled, start the bike and let it run for a minute—this circulates the new oil and fills the filter chamber.
- Turn off the engine and let oil settle for a couple minutes.
- With the bike standing vertical, check oil level through the sight glass.
- Top off oil as needed so the level is at the top of the red circle in the sight glass—don't overfill.
-
Final Checks
- Inspect for leaks at the drain bolt and filter cover.
- Wipe off any spilled oil and reinstall the skid plate if removed.
- Dispose of used oil and materials responsibly at a local recycling center.
Special Call-Outs for the 2020 KTM 250SXF
-
Oil Change Intervals: KTM recommends an oil change:
- After initial break-in (first hour of engine time),
- Then after every 10 riding hours or race interval.
- Wrench Clearance: Due to the frame design, a socket does not fit directly onto the drain bolt—use an open-end wrench for easier access on the 2020 250SXF.
- Drain Plug Magnet: Clean metal debris from the magnet at every oil change—this helps monitor engine wear and protects internals.
- Torque Values: Overtightening the drain bolt or oil filter cover can cause serious damage. Consult the owner's manual for current torque specs and use a calibrated torque wrench.
- Oil Capacity: The 2020 KTM 250SXF oil capacity is slightly less than 1 liter. Always confirm via the sight glass after running the engine—it's better to top off slowly than overfill.

- Always use good quality, KTM-approved oils and filters for best performance and longevity.
- Keep a log of your maintenance intervals and used parts; this is valuable for resale and for tracking engine health.
