Tools and Supplies Needed

- Quantity: Approx. 1.2 liters when changing the filter
Step-by-Step Oil Change Instructions
-
Warm Up the Engine
- Start your KTM 250XCF and allow it to idle for a few minutes. Warm oil drains more thoroughly.
-
Stabilize the Bike
- Place the motorcycle on a stable, level surface using a bike stand.
-
Drain the Old Oil
- With gloves on, use the correct socket to remove the oil drain plug while positioning your oil pan underneath.
- Allow the oil to fully drain. Take care: hot oil can cause burns.
- Inspect and clean the magnetic drain plug and replace the brass crush washer to ensure a proper seal.
-
Clean Oil Screens
- The 250XCF contains a short and long oil screen. Remove the hex-socket plug (bottom of engine), then pull out and clean both screens with contact cleaner and a rag.
- After cleaning, reinsert the screens, ensuring they click back into place. Reinstall and torque the plug to 15 Nm (11 ft.lbs) for screen cap, and 20 Nm (14.8 ft.lbs) for drain plug.
-
Replace the Oil Filter
- Locate the oil filter cover, remove the two 8mm bolts, and gently pry off the cover.
- Remove the old oil filter (use pliers if stuck). Clean the cavity with a rag and contact cleaner.
- Pre-oil the new filter by soaking it in engine oil, then insert it into the engine.
- Check and replace the O-rings if necessary. Reinstall the filter cap and bolts.
-
Refill with Oil
- Insert a funnel into the oil fill opening. Pour in 1.2 liters of new oil. Adjust volume as needed by sight glass – it should rest just above halfway when settled.
- Reinstall and tighten the fill cap. Torque cap using pliers to prevent loosening due to vibration or impact.
-
Run and Check
- Start the motorcycle and let it idle for several minutes, allowing the new oil to circulate completely.
- Switch off, let the oil settle, and with the bike vertical, check the level in the sight glass. Add oil if necessary.
-
Final Inspection
- Wipe down any spilled oil with a clean rag and contact cleaner.
- Inspect for leaks around drain plug, oil screen covers, and the oil filter cap.
- Dispose of old oil and filter at a certified recycling location.
2011 KTM 250XCF-Specific Call-Outs
- This model uses just one oil filter (not two, like some four-stroke KTMs) – be sure not to overbuy replacements.
- Always clean both the short and long oil screens at every oil change for this engine's health.
- Always check and replace O-rings and crush washers to prevent leaks, as the 250XCF engine is sensitive to pressure drops caused by minor seal failures.
- KTM recommends Motorex Power Synt 4T, but confirm the correct viscosity for your region and season using your owner's manual.
- Be careful not to overtighten bolts, especially on the aluminum cases. Use a torque wrench and always follow torque specs.
Important Safety Tips
- Do not change the oil immediately after aggressive riding; allow the engine to cool slightly to avoid burns, but keep oil warm for best flow.
- Use gloves and proper eye protection when handling used engine oil and chemicals.
- Never dispose of oil or filters in household trash – use appropriate recycling services.
