Tools & Supplies Needed
- 10mm and 8mm sockets/wrenches (for skid plate and oil filter cover bolts)
- Torque wrench
- Drain pan
- Gloves (for cleanliness and safety)
- Shop rags or paper towels
- Funnel
- Genuine KTM Oil Filter (OEM 77338005100)
- KTM Oil Filter Cover O-Ring (OEM 07703305178) (replace if worn)
- Crush washer for drain plug (replace every change for a proper seal)
- Motorex 10w50 full synthetic oil (use 1.2L for a full change)
- Plastic or rubber mallet (optional, for loosening stuck covers)
- Safety glasses (suggested for splash protection)
Step-by-Step Instructions
-
Warm Up the Engine
- Start your bike and let it idle for 3–4 minutes. This helps the oil flow out smoothly when draining.
- Turn off the engine and ensure the bike is on a stable stand, upright.
-
Remove the Skid Plate (If Installed)
- Use your socket to remove bolts securing the skid plate. Set bolts and plate aside.
-
Drain the Oil
- Locate the main oil drain plug under the engine (referenced in KTM's owner manual).
- Position your drain pan beneath the plug.
- Remove the drain plug with the correct socket. Allow oil to fully drain.
- Remove the crush washer and replace with a new one.
-
Remove and Clean Oil Screens
- 2019 KTM 250SXF features two oil screens: left and right sides of the engine.
- Unscrew both screens using the correct size wrench. Let residual oil drain.
- Inspect screens for metal debris, thoroughly clean them with solvent, and reinstall.
- Tighten to KTM’s specified torque (see your owner’s manual; typically 10 Nm).
-
Remove and Replace Oil Filter
- Using an 8mm wrench, remove the oil filter cover.
- Take note of the o-ring on the filter cover; inspect for wear and replace if needed.
- Remove the old oil filter and discard it.
- Pre-fill the new oil filter with a small amount of fresh oil (helps protect your top end on first start).
- Install the new filter. Pay close attention to orientation: The deeper, open end goes inside the engine. Improper installation can severely damage your engine.
- Replace the filter cover, aligning it properly, and torque bolts to spec (usually 10 Nm).
-
Reinstall Drain Plug
- With new crush washer, hand-thread the plug to avoid cross-threading.
- Tighten drain plug to correct torque (typically 15 Nm).
-
Add New Oil
- Using a funnel, fill your engine with 1.2 liters of 10w50 Motorex full synthetic oil.
- Replace the oil fill cap when done.
-
Check Oil Level
- Start the bike and run for 1–2 minutes. Shut off and let oil settle for several minutes.
- With the bike upright, check oil level via the inspection window or dipstick. Add oil if the level is below the top line of the red circle. Do not overfill.
-
Reinstall Skid Plate
- Secure it back in place using the removed bolts.
2019 KTM 250SXF FACTORY EDITION: Special Notes
- Oil capacity is 1.2L; do not exceed this amount.
- Always replace the crush washer to prevent leaks.
- Pay special attention to oil filter orientation; the wrong installation can destroy engine components immediately.
- Torque all bolts according to the owner’s manual. Over-tightening can strip cases.
- Use only high-quality, fully synthetic oil, such as Motorex 10w50, for best performance.
- Check both oil screens for metal debris — excessive particles may indicate internal wear.
- After your first oil change on a new engine, check oil again after your first ride, as sometimes oil settles or leaks develop from improper installation.
Troubleshooting After Oil Change
- If oil level drops significantly after first start, let the bike cool, then top off to proper level.
- If leaks occur, stop engine and check all bolts, especially the drain plug and filter cover.
- Engine sounding unusually noisy? Stop immediately and check oil level and filter orientation.
